Internet Telephony: Architecture and Protocols - an IETF Perspective
نویسندگان
چکیده
Internet telephony offers the opportunity to design a global multimedia communications system that may eventually replace the existing telephony infrastructure. We describe the upper-layer protocol components that are specific to Internet Ž . telephony services: the Real-Time Transport Protocol RTP to carry voice and video data, and the Session Initiation Ž . Protocol SIP for signaling. We also mention some complementary protocols, including the Real Time Streaming Protocol Ž . Ž . RTSP for control of streaming media, and the Wide Area Service Discovery Protocol WASRV for location of telephony gateways. q 1999 Published by Elsevier Science B.V. All rights reserved.
