QoS processing method, apparatus and system based on stream

Abstract

The embodiment of the invention provides a method for processing service quality, a device and a system based on a stream. The method for processing the service quality based on the stream comprises the following steps: according to a real-time transmission protocol RTP data stream feature sent by a control plane, replicating an RTP message according with the RTP data stream feature to send to the control plane; studying the RTP message sent on the control plane; carrying out QoS treatment to an RTP data stream according to the QoS control strategy of the RTP data stream monitored and sent bythe control plane after the RTP data stream is identified and monitored according to the RTP message. By applying the invention, the data stream of a specific client which is only discarded can be achieved under the condition of network congestion, and the data stream of other clients can not be influenced; and a complicated signaling protocol and various devices arranged in a network can not be required.

Description

technical field [0001] The present invention relates to the communication field, in particular to a flow-based QoS processing method, device and system. Background technique [0002] RTP (Real-Time Transport Protocol, Real-Time Transport Protocol) is a transmission protocol for multimedia data streams on the Internet, and is published as RFC 1889 by IETF (Internet Engineering Task Force, Internet Engineering Task Force). RTP is defined as working in the case of one-to-one or one-to-many transmission. Its purpose is to provide time information and realize stream synchronization. It mainly provides services such as load type identification, sequence number, time positioning and transmission monitoring. The typical application of RTP is based on UDP (User Datagram Protocol, User Datagram Protocol), but it can also work on other protocols such as TCP (Transmission Control Protocol, Transmission Control Protocol) or ATM (Asynchronous Transfer Mode, Asynchronous Transfer Mode) . ...

AI Technical Summary

Problems solved by technology

[0022] The method of implementing flow-based QoS processing through a router requires the router to support complex signaling protocols, which has a large workload and complicated processing procedures, which affects efficiency (the router is not a protocol gateway, and the main work of its CPU should be used for the maintenance of the routing protocol); Implementing flow-based QoS processing through gateway devices requires the deployment of various types of devices. Routers and gateway devices support linkage protocols for cooperative settings. The network is relatively complex and requires high equipment requirements.
