Abstract

The factors limiting widespread availability for Next Generation Services are mainly due to the different mix of network solutions that will coexist in the next future. They are also related to the work in progress and the consequent evolution in the design of network architectures and in the protocols area.

A great deal of applications based on H.323 is already in operation while SIP is emerging as the protocol for implementing next generation services. It is clear that interoperability is a great issue affecting not only call/session control signaling but also e2e QoS signaling and SLA Management.

These items are of great importance for a timely deployment of services which is now achievable thanks to the open service architectures and programmable platforms. There is also a strong need for integrated management techniques in order to realize a commodity pricing based on QoS. It will be required to establish media streams according to precise QoS requirements with the opportunity to change them during the call/session mapping them to QoS classes ensuring end-to-end negotiation.

The project focuses on the means which will be available to achieve end-to-end interoperability in NGN providing QoS control and security. These means are related to signaling protocols extensions for the setup and tear down of media streams.

The project aims to integrate results provided in related areas in a network solution in which multimedia NGN softswitches play the main role in network resource control and allocation on a per-call basis.

Focus areas

E2E interoperability in NGN with:

network architectures and signalling protocols for controlling media streams
Quality of Service control and security
integrate results on network solutions with multimedia soft-switches for network resource control and allocation

Expected outcome

Bandwitdth E2E QoS management
QoS signalling mechanism (basic and SLA/ statistic pre-provisioning
Session control signalling inter-working and adaptation
Inter-working mechanisms with “network resource control” level
