Tutorial 1, November 6, 2008, 10:00 - 13:00
“IMS Basics, Standards Update and Future Challenges in face of Converged Internet/Telecoms”Presented by Prof. Dr. Thomas Magedanz & Niklas Blum - TU Berlin/Fraunhofer FOKUS, Germany
Telecommunications is at crossroads. The ongoing network convergence and the associated idea of providing seamless multimedia information and communication services demands for a structured and globally standardized all-IP service provisioning architecture. This is today represented by the IP Multimedia Subsystem (IMS), which is standardized by 3GPP, 3GPP2, ETSI TISPAN, and PaketCable. However, a common service platform is mainly driven by the enabled services on top of it. In this context a major challenge for IMS deployment and more importantly for the overall telecommunications industry in general is the increasing competition with "over the top" and internet multimedia service providers. Typical IMS applications, such as VoIP, conferencing, video streaming, messaging, presence, etc. are for free in the internet. Service bundeling concepts, such as FMC, triple and quad play are therefore demarkating an additional approach for delivering combinational services. One important question is however, how IMS and next generation telecommunication services compete or integrate with an increasing universe of Web 2.0 services, which represent the stateof the art in multiparty multimedia service delivery. Closely linked to this question is also the question about how IMS as a platform architecture links into Service Delivery Platforms (SDPs) and the corresponding notion of Service Oriented Architectures (SOA).
In this tutorial we want to introduce the IMS principles, architecture and services and discuss the above mentioned issues to provide the necessary base for the subsequent workshops and conference sessions. We will also introduce briefly the Open IMS Playground, as well as the related Open SOA Telco Playground and the Media Interoperability Lab. Thus newcomers to the subject will obtain a sound introduction and experts can gain an update about the key IMS deployment issues.

Tutorial 2, November 6, 2008, 10:00 - 13:00
“The Open IMS Core - A Reference Implementation for NGN Prototyping and Testing”Presented by Peter Weik & Dragos Vingarzan - Fraunhofer FOKUS, Germany
Since its release in November 2006 the Open IMS Core project (www.openimscore.org) has been used in numerous testbed installations all over the world that are dealing with NGN service delivery. While the first issues of this tutorial were devoted to introduce the project and to show how to get started, this time we want to outline on how to set up the software best for NGN service and component prototyping and testing.
The tutorial once more will cover the essential functions and implemented features of the four components that form the Open IMS Core, but we will mainly focus on the introduction on how to use them best for specific test cases and purposes. As some highlights, the tutorial will cover the motivation for using Open Source Software in IMS, in introduction to the Open IMS Core components, documentation & licensing as well as the configuration options of the Open IMS Core for interoperability, conformance and performance testing.

About Workshop 1: Understanding the convergence jungle: putting the buzzwords NGN, IMS, SDP, and SOA into the right context
Next Generation Networks (NGNs) are representing an important milestone in the evolution of fixed and mobile telecommunication networks towards an all-IP based multimedia services network environment. Positioned in the centre of the convergence of telecommunications and the internet, a major question arising is what kind of future multimedia killer applications will justify the huge investments to be undertaken for NGN introduction. Based on the success of the internet under the banner of Web 2.0 the hard lesson learned by the telecoms industry is, that there won´t be any single killer application in the future but rather a multitude of the niche services have to provided to a broadening spectrum of user groups also called communities. The IP Multimedia Subsystem (IMS) is supposed as international standard to provide as a structured over the top (OTT) service control architecture these kinds of presence-based community communication and information services.
However, the IMS is not standardizing how services have to be developed and provided in an efficient way. The notion of Service Delivery Platforms (SDPs) is addressing this spectrum of needed functionalities on top of various network types, including emerging NGN and IMS infrastructures. This means that SDPs and IMS are considered today as important platforms on top of NGNs for the efficient implementation of an open set of multimedia services. Efficiency in this context is enabled by the concept of reusable service components designed independently of underlying network technologies, which brings us to the notion of Service oriented Architectures (SOAs), which are considered today as holy grail for a future proof system design.
This half day workshop introduces the main buzzwords of converging networks and puts them into context. After a brief introduction of the FOKUS Open SOA Telco playground defining a SOA reference architecture on top of IMS and legacy network infrastructures, international experts will address in the first session SOA service creation principles and SOA key components and technologies on top of IMS and legacy networks. In the second session various operators will talk about their views and experiences of opening their networks to third party developers via open network application programming interfaces (APIs) in order to address the need to deliver appropriate services within an emerging open services market.
As this workshop is designed as an interactive workshop, enough time will be reserved to allow attendants a vivid discussion with the speakers, which could also be continued in a more relaxed atmosphere at the subsequent social event.
Composing Services... services as music
Prof. Noël Crespi, Institut National des Télécommunications, France
- What are the instruments? Service capabilities, OMA enablers, web services; the different interfaces.
- Who is the Composer? Who is the Conductor?
- Static vs dynamic service composition
Changing Paradigms: Services Push Towards Agile Development and Evolution
Prof. Bernhard Steffen, University of Dortmund
The combination of rigorous standards, simplicity by virtualization, agility through Service Orientation, and Quality of Service via Service Level Agreements (SLAs) changes the `physics´ of application development:
- architectures become internalized commodity,
- development and evolution become orchestration,
- quality of service becomes a matter of SLAs and monitoring.
Does this new recipe suffice to resolve the trade-off between high assurance and (user) process level agility?
Web 2.0 – IMS services for telecommunications
Naoki Takaya, NTT
In view of application service for NGN, some IMS based application services such as 3PCC, PoC and IMS presence can be provided using standardized technology specifications such as OMA enablers. However, it seems difficult to spread current IMS applications (e.g. IMS presence) widely as commercial services, because it is not attractive for general users including IT developers. In this presentation, we will show some ideas of Web 2.0-IMS application services (e.g. the presence with avatar using REST API interface), and we would like to discuss future Web 2.0 – IMS services for telecommunications.
Telco Meets Web 2.0: Why and How Embracing an Open Approach
Alberto Baravaglio, Telecom Italia
- Web 2.0 is strongly pushing a paradigm which moves part of the control of the value creation process to the end-users; this is happening in content generation, as well as in service creation. The new ecosystems are much more dynamic and challenging for Telco operators, requiring to be able to quickly adapt to the new demand
- Telco operators need to ride the Internet (r)evolution embracing a more open model, offering APIs and tools to easily integrate IMS and legacy capabilities in new ecosystems
- IT technologies and in particular Service Oriented Architectures provide tools and reference frameworks to enable the exposure of Telco capabilities to the Internet; both IMS and legacy resources must be adapted to the IT domain, identifying an appropriate level of exposure
- The implementation of a Service Oriented Architecture, is a huge project whose scope is not only the definition of IT oriented interfaces, but covers areas like security, accounting, service creation and, of course, protocol adaptation: a complete Service Delivery Platform is needed to put in place a SOA.
- The Telecom Italia Service Exposure is the implementation of a Service Delivery Platform that enriches the Service Layer with the functionalities required to expose IMS and non IMS capabilities to different domains, with the necessary flexibility to easily adapt to the ever changing needs of different types of consumers.
Critera for Successful APIs
Paul Crane, BT, UK
In response to the phenomenal success of web 2.0 services, telecommunication service provides must re-think their service propositions. Open API's are one key element. The presentation outlines this changing business landscape and the criteria for successful API's.

About Workshop 2: IMS and Converged Media Services – Challenges and Opportunities for Operator, Content Provider and Advertising Industry
The convergence of telephony, radio/TV broadcast and data networks towards All-IP infrastructures is under full activity. IPTV as a crucial column in the sphere of Triple Play is widely accepted and has established as 4th medium for TV content transmission in addition to terrestrial, satellite and cable bearers. Telecommunication operator have a big asset in their portfolio yet, as they have the experience of voice and data networks and seeking newly for experience in TV content transmission. Their competitors in the Internet domain are awake and push WebTV and Web 2.0 services as YouTube and Facebook as well as voice communication services as Skype. Operators have to consider the future as bit pipe. The lean back model of current IPTV deployments may be insufficient.
However, Next Generation Networks (NGN) (e.g. IMS) may be a last resort for them to face this challenge. NGNs allow rich communication (Presence and Instant Messaging) coupled with interactive TV scenarios over telecommunication networks within the Telco’s domain. Integrated identity management and QoS create a clear advantage toward the Internet world. The direct return link to the network allows personalization and offers complete new business models for content provider and advertisement industry.
This half day workshop introduces in the first session current perspectives of Lean back and rich communicative IPTV. Experts will discuss current trends and standardization activities. The second session then addresses chances and challenges for content provider and advertising industry in such future IPTV trends.
As this workshop is designed as an interactive workshop, enough time will be reserved to allow attendants a vivid discussion with the speakers, which could also be continued in a more relaxed atmosphere at the subsequent social event.
IPTV just a Telco walled garden?
An overview and introduction on current standardization activities and an insight into the Fraunhofer FOKUS Media Interoperability Lab
Oliver Friedrich, System Architect & Team Leader Media Interoperability Lab, Fraunhofer FOKUS
Up to now IPTV and work on corresponding ecosystems was driven mainly by different black-box approaches and ideas to built solutions based on NGN technology. Especially the integration of future all-IP telecommunication services and rich media entertainment into one platform were strong arguments for this approach. 2008 the Consumer Electronics industry, Advertisers and the different Content Providers entered the battle for IPTV demanding adapted or completely different business models for this emerging technology.
This talk will give an introduction and update on the last year’s presentation to the different bodies involved in IPTV standardization their view on IPTV issues and work being finished or currently carried out.
Furthermore the FOKUS Media Interoperability Lab - our platform for future Rich Media Entertainment integrating IMS based IPTV services - will be presented.

“Open NGN Testbeds – Infrastructure as a Service”Moderated by S. Wahle - Fraunhofer FOKUS, Germany & A. Gavras - EURESCOM, Germany
Abstracts of Workshop 3
About Workshop 3: Open NGN Testbeds – Infrastructure as a Service
With the progressing convergence of the internet and fixed and mobile telecommunication networks and emerging converged interactive multimedia applications leading to increased competition and more complex value chains, the early prototyping and experimentation of new service concepts and related enabling technologies will become a key means for driving innovation. In this context, the value generation has shifted from network technologies towards applications and content. Thus, the nature and scope of "testbeds" have changed substantially in recent years from solely network technologies towards complex service delivery infrastructures riding on various networks. In contrast to traditional vendor, operator and/or technology specific “closed” testbeds, the notion of “open testbeds" has emerged. “Open” in this context means both wide access as a shared resource and extensibility to include on-demand new end systems, network technologies, protocol stacks, and, most importantly, new middleware and service delivery platforms for specific test purposes. To meet this need, major research and development programs have started around the globe, including GENI in the U.S. and FIRE in Europe, to establish large scale experimental facilities.
There is no doubt these days that the IP Multimedia System (IMS) plays a central role as common service signaling middleware in face of converged networks and the Next Generation Network (NGN). IN this context we can witness an increasing number of testbeds promoting an open IMS infrastructure to implement new seamless multimedia applications.
This half day workshop introduces the main open testbed initiatives and discusses with global experts the benefis and challenges of such testbeds. After a brief introduction of the FOKUS Open IMS playground and the newest tools developed for it, international experts will share in the first session their experiences in setting up and running their own IMS testbeds based on the FOKUS open source IMS (OSIMS) core system. In the second session the major testbed initiatives in Germany and Europe will be presented and first experiences shared. A final panel will discuss with all speakers and the audience the business models for running open testbeds.
As this workshop is designed as an interactive workshop, enough time will be reserved to allow attendants a vivid discussion with the speakers, which could also be continued in a more relaxed atmosphere at the subsequent social event.

The European FIRE Facility - Status, Vision, Opportunities
Dr. Max Lemke, European Commission, Brussels, Belgium
In 2007 and 2008, several large European projects, which prototype a European experimental facility of interconnected testbeds have started. In the keynote presentation, a short overview of these FIRE projects and their priorities will be given.
The major focus of the presentation will be on the EU vision on how these prototypes are expected to evolve to build a European Experimental Facility for the "broader" internet researcher:
- expanded functionality to include testing on service architecture level
- system-level testing across interconnected testbed taking a holistic view and viewing the Internet as a complex system
- "right level" user involvement in testing
An overview of what is planned for the next Call for proposals related to FIRE (mid 2009) will be given. In particular the mechanism which are planned to be put in place to stimulate innovative evolution and use of the facility will be highlighted.
Experiences with a NGN Testbed - The Convergence Innovation Platform at Georgia Tech
Dr. Russell Clark, Georgia Tech, USA
The mobile application space presents numerous challenges for design, implementation and deployment. A particular problem is the limited availability of facilities that provide a complete end-to-end application development environment. The Convergence Innovation Platform (CIP) at the Georgia Tech Research Network Operations Center (GT-RNOC) provides extensive, supported, end-to-end resources for developing applications and conducting live trials. Features include handsets, SIP A/S and web services, both commercial and private access networks, and other enabling services such as presence and location.
The CIP provides a unique opportunity for carriers, equipment suppliers, developers and researchers to work with state-of-the-art technologies from both commercial and open source communities.
Bringing IMS Services Development to Everyone
Jose Antonio Rodríguez, Telefónica I+D, Spain
IMS seems to be a great idea and significant steps forward has been taken in platforms and networks. Now, it is time to drive IMS services development to demonstrate the feasibility of IMS. What do developers need to create new services based on IMS technologies and networks? They need a comfortable environment where they can learn IMS concepts, develop and test services, and check the services feasibility.
OSIMS, together with Application Servers, enablers -like Presence or Messaging Servers-, IMS clients, and a bunch of convenient tools, make up all the necessary elements for developers to create IMS services. Telefónica I+D proposes to pack up all together, including configuration tools, and by means of virtualization techniques, an open and redistributable IMS service creation environment will be available to companies, educational and technological centres, and end users in order to help them to make up new services.
In short: a personal and customizable IMS environment that makes easier the creation of new services.

OpenIMSCore Initiatives in Vietnam: Case Studies
Huu Thanh Nguyen, Hanoi University of Technology, Vietnam
The improvement of communications is not only about to create new and fantastic services, but also implies the migration and simplification of existing services. In today’s public networks, even NGN, there are neither products nor standardized solutions to provide corporate Private Branch Exchange (PBX) -like services. Currently, there are plenty of IP PBXs installed at corporate with rich set of IP Centrex features, e.g. call forwarding upon busy, call barring, etc. The example of such system is Asterisk, the most popular and open source IP PBX today, which is using SIP as session control protocol. While in the public side, IMS is approaching as the unique solution for the core of 3G and LTE networks. Therefore, there is a demand for integration and seamless interoperability between two domains, namely IMS at the core and IP PBX at the access/service layer. This short talk presents our initial experimental works for solving this problem. In our solution we propose to use Asterisk as the feature server on top of the Fokus’ OpenIMSCore to provide the IP Centrex services to IMS users. The proposed architecture will also use OpenSer as IMS Gateway to mediate between non-IMS Asterisk and the IMS core components. We also present the test-bed that was implemented in order to prove the concepts and presents key considerations for the implementation.
From iPhone to imsPhone: The BACCARDI Thin Client Approach for IMS Services
Marco Happenhofer, Telecommunications Research Center Vienna (ftw.), Austria
BACCARDI (Beyond Architectural Convergence: Charging, Security, Applications, Realization and Demonstration of IMS) is an application-oriented IMS-project conducted at the Telecommunications Research Center Vienna (ftw.) in close collaboration with mobilkom austria, Telekom Austria, Kapsch CarrierCom, Alcatel-Lucent and TU Vienna. In this talk we present some specifically interesting project results related to seamless provider-centric creation and deployment of IMS and beyond services. We focus on SHIP as combination of SIP and HTTP protocols, blending session control and content delivery, which we argue to provide a novel and sustainable approach for opening IMS towards the web community of both users and designers, and draw a couple of important conclusions both for network and service providers as well as application designers.
Large scale testing based on use cases
Anastasius Gavras, Eurescom
In the context of the project PII a significant effort is underway to implement the infrastructure necessary to support the deployment of the Pan-European Laboratory for next generation networks and services as defined in the Panlab framework. In order to illustrate how this facility can support future internet research and experimentation we use the concept of use cases. These use cases serve twofold:
- to extract concrete customer requirements and
- to stimulate the future usage of the facility.

G-Lab: A Future Generation Internet Research Lab
Rastin Pries, University of Wuerzburg, Germany
Todays Internet has a large economic influence but is based on legacy mechanisms and algorithms from the 70ies and 80ies. New applications have high demands for which the original Internet architecture was not designed for. The goal of the G-Lab project is to foster experimentally driven research to exploit future internet technologies.
The G-Lab project consists of a Germany-wide research and testbed platform used to investigate the interplay between new technologies and the requirements of emerging applications. The BMBF funded project consists of 10 partners from both industry and academia. It starts in autumn 2008. The G-Lab testing facilities consist of wired and wireless hardware with at least 25 nodes at each side which are fully controllable by the G-Lab partners.
Embedding P2P Technology in Next Generation Networks: A New Communication Paradigm & Experimentation Infrastructure
Spyros Denazis, University of Patras, Greece
Emerging types of applications, rich in user-created or provider- created content, enabled by P2P technology, with high demands for network resources are rapidly changing the landscape of network requirements and operations creating new challenges in network and service management, configuration, deployment, protocols etc. P2P is primarily a technology that fosters self-deployment and self-organisation, thus, reducing operational costs, while it achieves optimised resource utilisation for the deployed applications and services. In contrast, IMS as a control plane technology primarily addresses issues of heterogeneity of access technologies, addressing schemes, AAA, security and mobility management. This presentation presents the current status of VITAL++ an FP7 project, that major objective is to combine and experiment with the best of the two worlds, namely, IMS-like control plane functionality and P2P technology giving rise into a new communication paradigm that will bring a wide range of benefits.

About Workshop 4: IMS/NGN Interoperability
In the recent years, we have seen a strong adoption of IMS concepts into NGNs of telecommunication providers worldwide. Networks are moving from trial phases to staging systems. Yet, there is still substantial need for checking the interoperability of these NGN implementations before we will see any widespread deployments. This workshop will bring together representatives from all major IMS bodies who will share their views of the state of the industry efforts towards interoperability and will give vendors a possibility to present tools and approaches to optimize IMS interoperability and testing.
IMS Interoperability - BSS, Charging, Billing
Dr. Tomás Kovár - HP
One of the most significant aspects of IMS, although very often neglected, is the openess of its architecture and the clearly defined and standardised open interfaces. This opens the way for the communication service providers to establish the network, OSS and BSS optimised architectures from best of breed components, instead of monolitic proprietary silos that would create high dependency on network equipment vendors. Proving and manifesting this interoperability is one of the main targets of the IMS/NGN Forum, especialy its Plugfest events, where participating manufacturers demonstrate and certify their compliance to the 3GPP IMS standards and thus their interoperability.
MultiService Forum - IMS Interoperability Testing and Experiences
Dr. Albrecht Schwarz - Alcatel-Lucent
In order to arrive with the vision of operational and high performance IMS networks in the real world, intensive interoperability and conformance testing needs to take place. Industry forums such as the MultiService Forum (MSF) have invited for interoperability and certification events to systematically tackle these challenges. This presentation focuses on strategies, tools, challenges and lessons learned from IMS interoperability testing projects within the "Global MSF Interoperability" test program:

IMS Interoperability Testing Experience
David Boswarthick, ETSI TC TISPAN, France
IMS interoperability is a key issue for boosting IMS Interconnection between operators. IMS Interoperability performed by ETSI Plugtest play a central role not only to provide feedback to standardization but also to the industry and operators.
A new ETSI Technical Committee called TC INT (IMS Network Testing) has been created from the IMS-TEST-Board ad hoc group. This new Technical Committee will fill the existing gap for the IMS Core Network standards/specification testing activities, and will establish a stable bridge between standardization and industry through the execution of IMS Interoperability events in connection with ETSI Plugtests. This will also allow to promote IMS by coordinating relevant Plugtest events with other events/activities such as those organised by OMA, MSF, IMS Forum, etc.
Good results have been reached during 1st IMS Interoperability Event, in Turin, Italy, October 2007. A second IMS Interoperability Event will be held in Bled, Slovenia, 10-14 November 2008. The testing scope of this event includes testing of IMS roaming, border control, and integration of application services based on some selected supplementary services, with target IMS specifications 3GPP Rel 7.
During this events vendors will have the opportunity to show selected demonstrations of the latest IMS services and applications like rich communication services (RCS), also potentially involving mobile devices, as well as IMS testing tools.
Enabling and Testing IMS within the Open Mobile Alliance
Howard Greenwell - Director of Technical Programs, Open Mobile Alliance Ltd., UK
This presentation will address the issues surrounding the implementation of OMA Enablers in the IMS Environment -- from the definition of OMA's “IMS in OMA Reference Architecture” to the organization and establishment of an IMS test environment. Included will be standards issues, challenges and successes of bringing OMA Enablers into an IMS environment as well as the convergence of Mobile and Next Generation Networks.
How to increase efficiency in interoperability testing by using test automation frameworks
Theofanis Vassiliou-Gioles - Testing Technologies
Interoperability has a significant importance when introducing new applications and services in modern communication networks. As there is no way to guarantee interoperability between products of different vendors, interoperability testing is gaining more and more importance for the success of new services.
Due to the nature of interoperability testing, the majority of testing efforts is spent into manual testing. While manual testing suffers from well known problems it is mostly considered the only economical way to test interoperability.
One of the main bottlenecks when striving for test automation is associated to the costs for creating automated tests for interoperability testing.
This presentation will show a standards-based approach on how to decrease costs for test automation support in an interoperability test scenario. It will discuss the applicability of test frameworks in interoperability testing and will present a selected case study for this approach.

Messaging Evolution and the IMSFrank Hartwig, Swisscom AG, Switzerland
After successfully deploying the IMS Core and developing a Voice over Broadband service based on the IMS technology Swisscom is now entering a new phase of the IMS program. The aim of this phase is to extent the IMS Core so that next generation communication services as well as legacy voice and messaging services can be delivered on one network. The presentation will introduce a network architecture that places the IMS Core at the center of network control and is designed to enable the convergence of legacy and next generation communication. The presentation will further go into details on how Swisscom plans to deliver legacy messaging services like SMS and MMS over the IMS as well as integrating these legacy messaging services with new services like IM, Presence or file sharing with the aim to offer an integrated and consistent experience to the consumer.

Triple Play in a Carrier Network - Experiences and Outlook
Dr. Walter Haeffner, Arcor, Germany
We briefly review the economical and technological reasons why Vodafone Arcor decided to replace ISDN voice service offers by SIP based VoIP services as early as in 2006. We further discuss some essential network and service design aspects we were confronted with in introducing such a service. Meanwhile this consumer service offer not only covers VoIP and Broadband Internet but also IPTV whose introduction was a challenge in itself.
Competitiveness requires not only to provide his customers with the best service quality but also with a rich portfolio of advanced useful or at least interesting applications. This naturally leads to the question for an appropriate architecture and standard supporting the implementation of such profitable future applications in a simple way. From this perspective we review some potential benefits IMS may have as compared to our current more traditional SIP implementation.
Telco 2.0 and Web x.0 Integration
Thomas Mörsdorf, Deutsche Telekom AG, Germany
In this session we will look at new challenges in the competitive telco and web marketplace. Why will telcos have to open up key assets and services for external partners and developers? What opportunities and risks may arise? What will be the impact on the overall application and network architecture? What are resulting requirements towards standardisation?

IMS in North America - A survey of projects
Russell Clark - Georgia Tech, USA
In many ways, the North American marketplace has been slower to embrace IMS than other parts of the world. We'll talk about some of the reasons for this and take a look at several projects that are underway. We'll look at recent developments in the application and handset space and how they will affect the future of IMS.
IMS leads to introduce NTT's NGN in Japan
Tatsuro Murakami - NTT, Japan
NTT has launched NGN services since March 2008.
NTT's NGN has two remarkable characteristics; one is a network infrastructure for triple play services targeted for optical access, and the other is a platform to promote new services partnering with various service players. IMS is a key element to realize them.
This presentation explains how NTT has introduced NGN and what kind of roles IMS has played in this process.

Emerging Infrastructures for Research on the Future Internet and its Services – The European FIRE Initiative
Georgios Tselentis - European Commission, Brussels, Belgium
The first wave of projects under the European FIRE "Future Internet Research and Experimentation" Initiative has started in summer 2008. In the future, FIRE is expected to evolve along its two interrelated dimensions, with a new wave of projects envisaged to begin in 2010:
- The FIRE Facility shall evolve towards becoming fully operational. In parallel, it is planned to expand the concept, by addressing as well the service architecture layer, by supporting experimentation which cuts across layers, by enabling socio-economic impact assessment, as well as by broadening the involvement of large user communities.
- The FIRE experimentally-driven research shall further push the limits and define the challenges for the FIRE facility through visionary, multidisciplinary research, which considers the Internet as a complex system and therefore addresses all the associated aspects, in a holistic vision, at all relevant levels and layers.
It is planned to briefly give an overview of the FIRE activities, the strategy behind, and the future vision and plans, with special focus on the service dimension.
