Problems solved by technology

At the same time, after the service is opened, the PW parameters at both ends may be modified and debugged repeatedly, which makes the service interruption time longer
[0004] Since the RSG on the core side may need to establish a PW service with each CSG on the access side, this requires a lot of manpower to maintain and configure the PW parameters of the CSG and RSG, and it is easy to configure errors, resulting in poor communication between the two ends

Embodiment 1

[0072] At present, a large number of L2VPN services in the IP bearer network need to establish an end-to-end PW service between the CSG on the access side and the RSG on the core side, and usually the PW service established between the RSG and CSG is in the form of a Hub-Spoke.

[0073] Specifically, such as Figure 6 As shown, client A and client B need to perform L2VPN services. After the CSG on the client A side establishes a PW service with the RSG on the core side, client A and client B complete the L2VPN service. Among them, in the actual network, there are usually multiple CSGs on the access side, and only a few RSGs are configured on the core side. In this way, multiple CSGs on the access side will establish PW services with the same RSG, forming a Hub-Spoke .

[0074] On the PW service path established by each CSG and RSG, a PW switching node may also be included. In the present invention, the CSG, RSG and PW switching nodes on the PW service may be collectively refe...

Embodiment 2

[0112] Based on the method for configuring pseudowire PW parameters provided by the above-mentioned embodiments, when the first PW node learns the first PW parameters of the second PW node, both the first PW node and the second PW node can first initiate a request, that is, to The peer sends a label request mapping message. As long as the interfaces of the first PW node and the second PW node are connected, both the first PW node and the second PW node can initiate a request at the first time.

[0113] In the following embodiments of the present invention, the method is specifically described by using an interactive process in which the first PW node learns the first PW parameters of the second PW node in various situations.

[0114] Specific as image 3 As shown, in the scenario where the second PW node configures the PW parameters of the first PW node, after the first PW node accesses the network, the second PW node actively negotiates the PW parameters with the first PW no...

Embodiment 3

[0138] Based on the method for configuring pseudowire PW parameters provided in the foregoing embodiments, this embodiment of the present invention provides a first PW node that implements the method for configuring pseudowire PW parameters described above. Specifically, as Figure 7 As shown, the first PW node includes: a receiving unit 71 , a processing unit 72 and a sending unit 73 .

[0139] The receiving unit 71 is configured to receive a first label request mapping message sent by a second PW node, where the first label request mapping message carries a first PW parameter of the second PW node.

[0140] The processing unit 72 is configured to configure the first PW parameter as the PW parameter of the first PW node.

[0141] The sending unit 73 is configured to send a first label request mapping response message to the second PW node, where the first label request mapping response message includes first information, and the first information is used to indicate that the ...

Abstract

The embodiment of the invention provides a method for pseudo-wire PW parameter configuration and PW nodes so that manpower cost of maintenance and configuration of PW parameters can be reduced and thus the communication quality can be improved. The method includes the following steps: a first PW node receives a first label request mapping message sent by a second PW node, wherein the first label request mapping message carries a first PW parameter of the second PW node; the first PW node configures the first PW parameter into a PW parameter of the first PW node; and the first PW node sends a first label request mapping response message to the second PW node, wherein the first label request mapping response message includes first information used for representing that the first PW node configures the first PW parameter into the PW parameter of the first PW node. The method for the pseudo-wire PW parameter configuration and the PW nodes are applied to the technical field of communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for configuring pseudowire PW parameters and a PW node. Background technique [0002] At present, a large number of IP bearer networks, such as Layer Two Virtual Private Network (Layer Two Virtual Private Network, L2VPN for short), Cell Site Gateway (Cell Site Gateway, CSG for short) on the access side and wireless service gateway (Radio Service Gateway, The pseudowire (Pseudo Wire, PW) connection between RSG for short) presents a radial (English: Hub-Spoke) model. [0003] In the prior art, before the two ends of the CSG and the RSG are connected, it is necessary to negotiate whether the PW parameters of the two ends are consistent. If the PW parameters of the two ends are consistent, the CSG and the RSG are connected. However, PW parameters at both ends are generally manually configured by deployment or maintenance personnel to ensure consistency of PW paramete...
