Problems solved by technology

[0011] Defect 1: Different services cannot be provided for different levels of traffic entering the DS-TE tunnel
[0012] Defect 2: Different services, bandwidth isolation, and statistical multiplexing of bandwidth cannot be provided for the traffic of different users entering the DS-TE tunnel
The two parameters of 200M and AF4 here are also for the carrier network, that is to say, the user's packets have a bandwidth guarantee of 200M when passing through the carrier network, and enjoy the service level of AF4 at the same time, but the traffic of VPN b and VPN c Mixed together, the bandwidth of 200M cannot be allocated reasonably
[0013] Defect 3: Combining Defect 1 and Defect 2, figure 1 Tunnel 2 in Tunnel 2 provides 200M AF4 service for VPN b and VPN c users. In addition to not being able to allocate bandwidth between different users, it is also impossible to provide differentiated services for different levels of traffic within a user

Embodiment Construction

[0031]Construct a DS-TE tunnel classification scheduling table, configure the generation module to issue a DS-TE tunnel classification scheduling table, this table is indexed by VPN_index+Tunnel_index+Interface_index. VPN_index is used to distinguish VPNs. 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, depending on which DS-TE tunnel corresponds to Network topology, different DS-TE tunnel entrances have different scheduling methods, so it is necessary to add tunnel_index in the search key of 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 inbound interfaces (a Provider Edge accesses multiple Customer Edge devices belonging to the same VPN). If you want to be able to schedule equal access to the traffic from different inbound interfaces of the sa...

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 present invention relates to the technical field of network communication, in particular to a method for providing QoS services for virtual private network users based on a traffic engineering DS-TE tunnel based on differentiated services. Background technique [0002] Virtual Private Networking ("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 line and connect to the local Internet (Internet). Organizations in various places can transfer information to each other. At the same time, enterprises can also use Internet dial-up access equipment to allow their users to dial into the Internet and enter Enterprise network. The use of VPN has the advantages of cost saving, remote access, strong scalability, easy management and comprehensive control. [0003] In the prior art, the differentiated service tr...
