Embodiment Construction

[0021] A detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0022] As shown in FIG. 2 , FIG. 2 is a flowchart of a method for guaranteeing data stream QoS in Embodiment 1 of the present invention. Include the following steps:

[0023] In step 201, the border network device judges the type of the received message.

[0024] When a client network device in a certain L2VPN sends a message to another client network device, it needs to be forwarded through the border network device connected to the client network device. In practical applications, the packets sent by the client network device are very rich, including: voice, video, data and link protocol packets, and so on. These sent messages can be divided into: data messages and protocol messages, wherein the data messages and protocol messages include many types respectively. In order to provide different QoS guarantees for various packets, it is necessary to imp...

Abstract

The method includes following steps: borderline network device (BND) determines type of the received message; then, based on the type of the received message, BND picks up information of Quality of Service (QoS) ID of message; finally, based on QoS information corresponding to information of QoS ID, BND carries out transmission for message. The invention also discloses device for guaranteeing QoS of data stream so as to solve the guarantee issue of different QoS for different services of L2VPN. Thus, the inanition guarantees QoS.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for ensuring the quality of service of a data stream. Background technique [0002] Today, with the vigorous development of various services on the Internet, network users have put forward higher requirements for the service capability of network delivery packets, not only requiring the correct delivery of packets to the destination, but also generating delays, delay jitter, Packet loss rate and other indicators of transmission performance requirements. QoS (Quality of Service, service quality) evaluates the ability of the network to provide support for these service requirements. QoS is to provide different quality of service according to the different requirements of various applications, such as providing dedicated bandwidth, reducing message loss rate, reducing message transmission delay and delay jitter, etc. [0003] As shown in FIG. 1 , ...
