Next-Gen open Service Solutions over IP (N-GOSSIP)

closed

SIP (Session Initiation Protocol of IETF) is becoming a key technology enabler for Next Generation Services. In fact, some Telecom Operators are already using SIP for initial service offering (e.g. MCI in the US and Telia in Europe). On one side, some SIP based solutions are emerging, and consequently it would be very detrimental for the European Industry and particularly for the Eurescom Community if PNOs are not aware of this and cannot exploit the advantages promised by this new technology. On the other side, SIP technology still has to solve a number of issues before it can be widely deployed in European networks: e.g., consolidation of the protocol primitives, quality of service mechanisms, scripting languages, interaction with Application Servers etc.
The main goal of the Project is to demonstrate the feasibility of constructing and deploying large numbers of new telecommunications services over IP networks using open SIP solutions. The envisaged service platform will be accessed by heterogeneous terminals such as multimedia PC, PDA and IP phones and will support personal and service mobility, multimedia, any to any and multiparty communication.

What are the main objectives of this Project?

• Assessment of SIP technology and its business case with respect to rapid service provisioning.
• Evaluation of SIP based products and demonstration of service development.
• Definition and promotion of an open software platform for value added services.
• Deployment of existing and new telecommunications services over the Internet using a distributed SIP based platform

What are the key results of this Project?

• Assessment of SIP for new telecommunications services over IP Networks, gaining a better understanding of the business context for SIP and migration strategies.
• Contribution to standardization bodies and consortia: feedback from experimental activities on open technical issues under investigation in standardisation context (SIP and security issues, QoS, Firewalls, etc.).
• Promotion of the idea of a SIP Service Platform
• Demonstration of service development according to the SIP approach and assessment of available products.
• Recommendation to PNOs about benefits/drawbacks of SIP for Next Generation Networks

What relationship exists to other organisations or bodies?

The most important standards body in relation to SIP is IETF. A functioning SIP platform implements several protocols that are developed in many IETF WGs, including SIP, IPTel, SPIRITS and PINT. In addition to IETF, other bodies contribute to areas like service creation, 3^rd party call control, and interoperation with legacy networks and services. These bodies include JAIN community, Parlay Group, 3GPP, OMG, ITU, and ETSI.
