Embodiment 1

[0065] In this embodiment, it is assumed that an existing pseudowire is called the active pseudowire. Now for MBB, a new multi-segment pseudowire needs to be established in the way of explicit routing. When the active MS-PW fails, the traffic will be transferred to this A newly established MS-PW is called a standby pseudowire. Figure 4 In order to show the structural diagram of two multi-segment pseudo-wires sharing the same LSP in the routing scenario, as shown in Figure 4 As shown, the active / standby MS-PW can share the same LSP on the PW segment between TPE1 and SPE1, where MS-PW1 is the active MS-PW, and MS-PW1 is the standby MS-PW; similarly, the active / standby MS-PW The PW segment of MS-PW between SPE3 and TPE2 can also share the same LSP. An Access Group Identifier (AGI, Attachment Group Identifier), a Source Attachment Individual Identifier (SAII, Source Attachment Individual Identifier) ​​and a Target Access Individual Identifier (TAII, Target Attachment Individual...

Embodiment 2

[0101] In this embodiment, it is assumed that an existing pseudowire is called the active pseudowire. Now for MBB, a new multi-segment pseudowire needs to be established in a dynamic routing mode. When the active MS-PW fails, the traffic is transferred to this A newly established MS-PW is called a standby pseudowire. Image 6 It is a schematic diagram of the structure of two multi-segment pseudo-wires sharing the same LSP in the dynamic routing scenario, as shown in Image 6 As shown, the PW segment between TPE1 and SPE1 can share the same LSP, and the PW segment between SPE3 and TPE2 can also share the same LSP. Image 6 shown in the application scenario, with Figure 4 The shown application scenarios are basically the same, and the only difference lies in the routing manners on which the two are based. Can refer to Figure 4 understand the relevant descriptions.

Abstract

The invention discloses a multi-segment pseudo wire shared bandwidth method, and sets a same bandwidth sharing identifier for pseudo wires sharing a same tunnel. The method comprises the following steps: a PE (provider edge) node sends a label mapping message for the pseudo wires capable of sharing the same tunnel, and the label mapping message carries the bandwidth shared identifier. The invention simultaneously discloses the PE node which is applied to an edge-to-edge pseudo wire simulation system which sets the same bandwidth shared identifier for the pseudo wires sharing the same tunnel. The PE node comprises a sending unit used for sending the label mapping message for the pseudo wires sharing the same tunnel and other PE nodes, wherein the label mapping message carries the bandwidth sharing identifier. The invention discloses a multi-segment pseudo wire shared bandwidth system which comprises PE nodes which are connected through the pseudo wires, and the PE nodes are the above mentioned PE nodes. A technical scheme in the invention has the characteristics of easy realization, low cost and strong versatility.

Description

technical field [0001] The present invention relates to a multi-segment pseudo-wire (MS-PW, Multi-Segment Pseudo Wire) technology, in particular to a method and system for multi-segment pseudo-wire sharing bandwidth, and a Provider Edge (PE, Provider Edge) node. Background technique [0002] With the development of IP data network, the scalability, upgradeability and compatibility and intercommunication capabilities of IP network itself are very strong, while the flexibility of upgrading, expansion and intercommunication of traditional communication networks is relatively poor, limited by transmission methods and The type of business, and the commonality of the newly built network is also poor, which is not suitable for intercommunication management. Therefore, in the process of upgrading and expanding the application of the traditional communication network, whether to build duplicate networks or make full use of existing or public resources to achieve the purpose of upgrad...
