¿µ¹®³»¿ë¿ä¾à | The Session Initiation Protocol (SIP) and the Session Description Protocol (SDP) are test-based protocols that use the UTF-8 charset, and were designed for rich bandwidth links. However, when SIP/SDP is run over narrow bandwidth links, the session setup time increases substantially, compared to an operation over a rich bandwidth link. The session setup time is decreased dramatically if the SIP/SDP signaling is compressed. IETF RFC3320 specifies signaling compression mechanisms. This standard defines SIP/SDP library so as to reduce the session setup time as much as possible by boosting the compression rate. | ||
