GSMA OneAPI - Enabling Cross-operator Applications Using Open Network APIs
Graham Trickey, GSM Association, UK

The GSMA OneAPI (Open Network Enablers API) is a framework and definition of an initial set of network APIs to allow developers access to operator assets and capabilities using a single API definition. This enables developers to write applications that are truly portable across many operators and simplifies access to operator assets and capabilities so that their applications can easily embrace mobile. The OneAPI project is now implementing regional pilots where OneAPI is available on a fully commercial basis from a single portal & service endpoint for all operators within a region.

Experiences from the Open Developer Garden
Thomas Mörsdorf, Deutsche Telekom AG, Germany

• Evolution of the 3rd party enabling market
• The challenge to create a competitive offer to 3rd parties
• Evolving 3rd party business models

A Telco's View on API Exposure - the BT Experience
Maria Cuevas, BT, UK

The telecommunications market landscape is changing and competition from new players is forcing operators to rethink their business models and explore how to make best use of their assets. This talk focuses on the opportunities for Telcos to open their capabilities to third parties and provides an overview of BT's primary exposure layer, the Ribbit platform.

RCS and Key Operator Benefits
Thibaud Mienville, France Telecom Orange, France

The purpose of this presentation is to provide an overview & latest updates (including recent achievements, overview of RCS set of features, RCS Release planning ...) about GSMA RCS Initiative on-going activities which address definition of an interoperable IMS Rich Communication Suite as well as an overview of the Orange and other operators go to market plans.

Triple Play from the Telco Perspective
Frank Lonczewski, Products & Innovation, Deutsche Telekom AG, Germany

In this talk, a general overview of Deutsche Telekom AG's IPTV product T-Home Entertain is given with focus on the convergent services available in the product. The presentation concludes by looking onto current digital TV product trends and some thoughts on the future of T-Home Entertain.

Preventing Congestion Collapse of SIP Servers
Prof. Henning Schulzrinne, Columbia University, USA

High call volumes can be triggered by popular radio call-in shows, ticket give aways, holidays or catastrophic events. As the request volume exceeds the call handling capacity, SIP servers suffer from congestion collapse, reducing the effective throughput to near zero.
We have developed and tested a set of algorithms for UDP transport that maintain near-100% throughput even under massive overload. For TCP, we discovered that the standard TCP flow control is insufficient to prevent congestion collapse, and that it needs to be augmented with appropriate call dropping controls.
Rather than dropping calls, we'd like to construct an infrastructure that can scale to any call load, without wasting capacity and energy during times of low and normal call volume. We are designing algorithms to build self-scaling architectures, based on our earlier work on self-scaling web server systems, implemented in our DotSlash system.

Intended Questions for Panel Discussion “How to get to NGN and how to get from NGN to Future Internet?”
Moderator: Prof. Dr. Thomas Magedanz, TU Berlin/Fraunhofer FOKUS

• How to get to NGN and how to get from NGN to Future Internet?
• How far is industry NGN deployment?
• What are today the NGN Killer applications above NGNs?
• What is the driving force for migration towards NGN, i.e. efficiency or IP traffic?
• How many NGN implementations are based on IMS today?
• FMC: How does NGN relate to Next Generation Mobile Networks? What are the impacts?
• Will the Evolved Packet Core (EPC) replace IMS in the long run as generic IP control platform above access networks?
• Could an EPC operate on a fixed access?
• Will LTE fit into the classic NGN landscape?
• What is today application #1 over NGN? Internet access?
• How about the newest US move towards network neutrality? Will there be impacts on business models and SDPs?
• Future Internet is emerging, i.e. post IP. How will this affect NGN architecture evolution?
• How will Future Internet research impact NGN/Next Generation Mobile Network standardization?

Standardization Paths towards the Integration of NGNs & Clouds
Assoc. Prof. Dr. Tatiana Kovacikova, University of Zilina, Slovakia

Leading innovation in the service and application domain can become critical for the future success and growth of telecom operators. Provision of IT services is becoming a common component in the strategy of telecom operators. For this, integration of two different “technologies” - NGN and grid & cloud computing is now being considered in standardization bodies. In this presentation, the relationship between grid and cloud computing and related standards will be discussed first. The approach taken by ETSI and ITU-T to support the integration of grid and cloud computing with the NGN architecture will be described.  Possible scenarios will be identified to show how grid and cloud technology could be exploited to improve the efficiency of NGN resources and to offer new IT services to consumers. Defining the best ways for integrating NGN with grids and cloud assumes the availability of interoperable grid and cloud solutions built by IT in conjunction with the telecom industry. Hence, the ETSI activities towards this objective will be discussed. 

FI Technologies in Practice
Marcin Pilarski, Polish Telecom/Warsaw University of Technology, Poland

The roadmap from research innovation to commercial service in large Telco will be presented. Also future trends of network services at PlanetLab/OneLab related testbeds will be described.
