Functional Composition

There are two main challenges for flexible and network-aware service provision. The first challenge is the end-to-end networking paradigm, which is based on a service and data-unaware transport, and the second challenge is a lack of high-level communication abstractions. In this demo we approach both challenges. To address the first point we propose a methodology to integrate the Network Provider with the process of service provisioning. The introduced cooperative service provisioning (CSP) enables an interaction between Service Provider, Network Provider and Client. CSP can be applied in classical Provider as well as novel Peer-to-Peer scenarios. To address the second point, we adopt a Service Overlay approach with strong relation to the Functional Composition principle. A new method based on the extension of Distributed Hash Tables (DHTs) is proposed to realise a distributed control plane for a decentralised and reactive creation of Function Chains.
