Transport service for session initiation protocol in SIP-T scenarios

Open publisher page 1 citations

Abstract

The traditional telephone service has undergone deep changes in the years concerning the techniques of commutation and signaling. Today, public switched telecom networks (PSTNs) and private integrated services networks (PINSs) are strongly directed to adopt IP-based backbone. If it is possible to transfer the voice on packet switching network, in such reliable way, using voice over IP (VoIP) techniques, there is not still a valid alternative to the signaling systems, reliable and unfailing, like signaling system n.7 (SST). Session initiation protocol (SIP) seems to be the best candidate. SIP is an application layer signaling protocol and the problem remains still opened for what it concerns the transport service to use. This paper discusses about pros and cons of the possible candidates. To evaluate performances we have achieved some simulations, using a new module for network simulator 2.
