CONFIANCE (CONFerencing IMS-enabled Architecture for Next-generation Communication Experience)
is an actual implementation of a conferencing framework compliant with the IP Multimedia Core Network Subsystem (IMS) specification. The architecture has been conceived at the outset by taking into account ongoing standardization efforts inside the various active international bodies (IETF, 3GPP, OMA, etc). At its current state, it is capable to provide audio conferencing facilities with session management capabilities and floor control. The system presented is intended to serve as a running experimental test bed useful for protocol testing, as well as field trials and experimentations.
Such platform has been realized in the framework of a collaboration activity involving the University of Naples and Ericsson's Nomadic Lab in Helsinki.
With this work we want to obtain experimental results showing SCTP’s real benefits.
We will compare SCTP with already existing transport protocol and will analyze which real gains SCTP brings.
At present there aren’t SIP implementation that use SCTP as transport.
So we are modifying a SIP UA ( KPhone) and developing Proxy in order to support all transport protocol: UDP, TCP, SCTP.
We have implemented a SIP module under NS simulator.
This module at present use only UDP as transport protocol.
