Abstract

The invention relates to a multimedia stream transmission method. The method comprises the following steps of: obtaining a port number of a calling terminal multimedia stream transmitting port, the port number of a called terminal multimedia stream transmitting port, a first port number corresponding to the calling terminal multimedia stream transmitting port and a second port number corresponding to the called terminal multimedia stream port transmitting by using signaling sent by a calling terminal, the response made by the called terminal after the called terminal receives a signaling forwarded by a server and a port matching list set in the server; and forwarding the received multimedia stream between the first and second ports. The invention also relates to a multimedia stream transmission system. The multimedia stream transmission method and the multimedia stream transmission system of the invention have the advantages of relatively few occupied kernel resources and relatively high forwarding speed.

Description

technical field [0001] The present invention relates to the field of data transmission, and more specifically, relates to a multimedia stream transmission method and system. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is an application layer signaling control protocol for creating, modifying and releasing sessions of one or more participants. These sessions can be Internet multimedia conferencing, IP telephony or multimedia distribution. SIP includes UAS, UAC, and a proxy server (Proxy server) that forwards the data flow between the above-mentioned UAC and UAS. The SIP proxy server is a network device that processes signaling associated with multiple calls; UAS and UAC allow point-to-point Calls are made through a client-server protocol. When a user wishes to call another user, the caller uses INVITE to request an initial call, and the request contains sufficient information for the called party to participate in the session...
