Toshiba Confidential 4 Integration with IETF Other IETF protocol standards can be used to build a SIP based application. SIP can works with existing IETF protocols, for example: –RTP Real Time Protocol -to transport real time data and provide QOS feedback. –RTSP Real Time Streaming Protocol - for controlling delivery of streaming media. –SAP Session Advertisement Protocol - for advertising multimedia session via multicast. –SDP Session Description Protocol – for describing multimedia sessions. –MIME – Multipurpose Internet Mail Extension –standard for describing content on the Internet. –HTTP – Hypertext Transfer Protocol - HTTP is the standard protocol used for serving web pages over the Internet.
