Abstract

The embodiment of the invention discloses a method, device and system for forwarding data by a real time streaming protocol (RTSP) proxy. The method comprises the following steps of: receiving an RTSP request of an RTSP client end by an RTSP proxy; generating a relevance relation list of a client end identification and a business identification according to the RTSP request; and forwarding the RTSP response message to the RTSP client end corresponding to the client end identification according to the relevance relation list. The invention solves the problem that the client end can not receive the response message because the RTSP proxy can not distinguish the RTSP client end to which the response message returned by a server belongs, perfects the function of the RTSP proxy and simplifies the processing flow of the RTSP proxy.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for forwarding data by a real-time streaming protocol agent. Background technique [0002] The Real Time Streaming Protocol (RTSP) is a protocol dedicated to media on-demand control, based on a server / client architecture. Both the client and the server can actively send messages to each other. A TCP connection must first be established between the client and the server, and all subsequent session control message exchanges will take place on this connection. Real-time streaming protocol 2.0 defines several main message methods to express the main functions required for control, and use these messages to control media stream transmission. For example, the message has description query DESCRIBE, get parameter GET_PARAMETER, option OPTIONS , Pause PAUSE, play PLAY, redirect REDIRECT, build session SETUP, set parameter SET_PARAMETER, end session TE...
