Problems solved by technology

[0004] In the current mapping and binding methods based on ordinary physical ports (ports) and VLANs, when the port and the VLAN to which the port belongs are mapped and bound and the mapping policies are inconsistent, conflicts will occur, resulting in packets that cannot be mapped or mapped incorrectly. , which may eventually cause the transfer to fail

Embodiment Construction

[0031] Since the existing mapping binding methods are only based on ordinary physical ports and based on VLANs, if you want to bind based on a certain trunk port or a certain vfi, you may need to bind one by one vlan or one by one port , more cumbersome, less flexible, not convenient enough. When there are many vlans or physical ports bound to a certain vfi or the binding relationship between the physical port and the vlan where it is located is inconsistent, using the existing binding strategy will appear cumbersome and even cause conflicts in the binding relationship. Therefore the present invention proposes two new mapping binding modes: the mapping binding mode based on trunk and the mapping binding mode based on vfi:

[0032]Configure the mapping strategy based on the Trunk group; when a packet entering from any member port of the Trunk group is forwarded through the VPLS tunnel, execute the mapping strategy configured on the trunk group for the packet, and the mapping st...

Abstract

Disclosed are a method and a system for configuring quality of service mapping in a VPLS network. The method comprises: judging, after receiving a packet, the priority of mapping binding modes associated with a physical port that receives the packet; selecting a mapping binding mode according to a preset rule, and using a mapping policy corresponding to the mapping binding mode as a mapping policy for the packet; and implementing the mapping policy on the packet when forwarding the packet through a VPLS tunnel. The present invention prevents transmission failure caused by packet mapping errors, and makes the mapping binding configuration more flexible.

Description

technical field [0001] The present invention relates to L2MPLSVPNDiffServ (two-layer MPLS virtual private network differentiated service) technology in the field of communication, in particular, relates to a configuration method of QoS (Quality of Service, quality of service) mapping on a VPLS (VirtualprivateLANservice, virtual private LAN service) network and system. Background technique [0002] In VPLS (Virtual private LAN service, virtual private LAN service) network applications, it is often necessary at the entrance of the tunnel to set the value of the 3-bit TOS (Type of Service, service type) in the IP header or the 3 bits in the packet VLANtag (label) header. The value of the PRI (Priority, priority) of the bit is mapped to the EXP (Experimental, experimental bit) of the MPLS (Multi-ProtocolLabelSwitching, multi-protocol label switching) label to determine each hop in the LSP (LabelSwitchedPath, label switching path) The queuing policy and discarding policy at the ...
