Embodiment Construction

[0040]Construct the DS-TE tunnel classification scheduling table, and configure the generation module to deliver the DS-TE tunnel classification scheduling table. This table is indexed by VPN_index+Tunnel_index+Interface_index. VPN_index is used to distinguish VPNs, and the index is obtained from the interface bound to the VPN; for Layer 3 VPNs, the DS-TE tunnels corresponding to different private network packets can be different, and the corresponding DS-TE tunnel depends on The topological structure of the network, different DS-TE tunnel entrances have different scheduling methods, so it is necessary to add tunnel_index to the search keyword in the DS-TE tunnel classification scheduling table; the reason for adding Interface_index in the DS-TE tunnel classification scheduling table The same VPN may have multiple incoming interfaces (multiple Customer Edge devices belonging to one VPN are connected to one Provider Edge). If you want to equally schedule the traffic between diff...

Abstract

The present invention discloses a method providing QoS ministrant to virtual special network user, capable of providing multi-user multiple service difference service to virtual special network VPN. Said method includes based on user scheduling ID, DSCP or 8021. P value and service scheduling ID to construct DS-TE tunnel classified schedule table, querying DS-TE tunnel classified schedule table, if configured multi-user scheduling and / or multiple service scheduling, obtaining user scheduling ID and / or service scheduling ID; according to said user scheduling ID and / or service scheduling ID, tunnel interface QoS scheduling process, providing QoS service.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for providing QoS service for virtual private network users based on a traffic engineering DS-TE tunnel of differentiated services. Background technique [0002] A virtual private network (Virtual Private Networking, referred to as "VPN") refers to the establishment of a private network in a public network, and data can be transmitted in the public network through a secure "encrypted channel". Enterprises only need to rent a local data dedicated line and connect to the local Internet (Internet), and institutions in various places can transfer information to each other. enterprise network. The use of VPN has the advantages of saving costs, providing remote access, strong scalability, easy management and full control. [0003] In the prior art, the scheme of DS-TE (DiffServ-Aware Traffic Engineering) providing QoS (Quality of Service) service for VPN is as ...
