Method and device for processing quality of service of ipv6 data packets

Abstract

The invention relates to a method and equipment for processing the quality of service of an IPv6 data packet. The method includes: a network edge device receives an IPv6 data packet, and the source address and / or destination address of the IPv6 data packet includes an address category field; The address category field included in the source address and / or destination address inquires the local QoS policy database, and obtains the corresponding QoS policy; the network edge device checks the IPv6 data packet according to the QoS level information in the QoS policy obtained from the query. mark the communication service category field. The invention enables the core network equipment receiving the IPv6 data packet to adopt corresponding forwarding priority processing according to the communication service category field marked by the network edge equipment based on the address category data. Through the above solution, the differentiated service quality identification of the business is realized, which is conducive to the low-cost realization of the service quality guarantee of the whole network.

Description

technical field [0001] The present invention relates to telecommunication and IT application technologies, in particular to a method and equipment for processing IPv6 data packet Quality of Service (QoS for short). Background technique [0002] Quality of Service (QoS) is a basic capability requirement of a carrier-class IP network. Its fundamental purpose is to provide differentiated transport services for different services and improve the efficiency of network resource usage. Since data communication is data transmission between two service nodes located in different locations in the network, QoS differentiated services need to be selected based on the service level attributes of nodes at both ends of the communication. Since the IP network is connectionless and has no end-to-end global control and global view, it is difficult for local network devices to obtain attribute information of remote communication nodes. [0003] In this case, the network device usually generat...

Problems solved by technology

In response to this problem, a solution proposed by the industry is to realize the remote transmission of related information by a stateful signaling party. However, the complexity, cost and cost of this solution are very high, and it is difficult to implement in a large-scale carrier-class IP network.

In short, under the existing network framework, it is difficult for the network equipment itself to know the service level of the remote broadband user, so it is not possible to perform QoS marking service according to the service category of the remote broadband user, and send it to different types of users when other conditions are the same The data transmission experience is basically the same and does not reflect the differences between different users, which means that only one-way quality of service is guaranteed
