Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0032] In order to achieve the purpose of the embodiment of the present invention, a virtual interface is established on the operator's edge device PE, and the virtual interface is used as the AC link interface in PWE3, and various service parameters are configured on the virtual interface as required, such as packet encapsulation Type, compression method of compressed packets, etc. The operator's edge device PE establishes a PW according to the PWE3 procedure, provides the PW as a tunnel to other services, such as a virtual private network, and binds the PW to a virtual interface to provide a new type of interface for other services to use. On the operator edge device PE, associate the destination address of the message to be forwarded with the corresponding PW, generate a forwarding table of t...

Abstract

This invention discloses a method and a device for setting up false-line tunnel to transmit message, in which, the method includes: setting up virtual interfaces on border devices of business runner of the outlet / inlet to take them as the AC link interfaces of the border devices to set up false bus PW and binding the virtual interfaces and the PW, the inlet business runner border device transfers the message to the customer border device via the virtual interface, the PW and outlet border device. This invention also provides a device for setting up false line tunnel to transmit messages including a virtual interface set-up module, a PW set-up module, a binding module and a message transfer module.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for establishing a pseudowire tunnel and using it to transmit messages. Background technique [0002] PWE3 (Pseudo Wire Emulation Edge to Edge-end-to-end pseudowire emulation) is a technical mechanism that can simulate important characteristics of telecommunication services on PSN (PacketSwitched Network-packet switching network). PWE3 Pseudowire PW (Pseudo Wire) encapsulates cells, packet data units, or inbound ports of specific service bit streams, and carries them through IP (Internet Protocol-Internet Protocol) or MPLS (Multi-Protocol Label Switching-multi-protocol Label switching) channel for transmission. PW provides the following main functions: 1. Encapsulate the specific service or circuit data arriving at the PE (Provider Edge-operator edge) device port; 2. Carry the encapsulated service data through the PSN channel; 4. Manage the signaling, timing, timin...
