Embodiment 1

[0033] Embodiment 1 of the data forwarding processing method of the present invention, such as figure 1 As shown, the method includes:

[0034] Step 101: The operator-side operator edge equipment (SPE) configures and manages the data forwarding information, the data forwarding information includes the forwarding information of the multi-segment pseudowire (MSPW) information and the MSPW protection link group or the forwarding information of the common MSPW Correspondence;

[0035] The forwarding information of the MSPW protection link group includes forwarding information of at least one active protection link and forwarding information of at least one standby protection link.

[0036] The present invention does not limit the form of the corresponding relationship between multi-segment pseudowire (MSPW) information and MSPW protection link group forwarding information or ordinary MSPW forwarding information, as long as the corresponding forwarding information can be found bas...

Embodiment 2

[0046] Embodiment 2 of the data forwarding processing method of the present invention, as figure 2 shown, including the following steps:

[0047]Step 201: The carrier edge device (SPE) on the carrier side configures and manages the MSPW member forwarding table and the MSPW protection group table;

[0048] The MSPW member forwarding table and the MSPW protection group table in this embodiment 2 are a specific form of expression, and the MSPW member forwarding table and the MSPW protection group table can be used to reflect the relationship between the multi-segment pseudowire (MSPW) information and the MSPW protection link group. Forwarding information or a corresponding relationship with common MSPW forwarding information.

[0049] Of course, the above MSPW member forwarding table and MSPW protection group table can also be integrated into one table, or divided into three tables reasonably.

Abstract

Disclosed are a method for processing data forwarding and a service-provider peripheral equipment (SPE) of a service-provider side. The method comprises the following steps: the SPE configuring data forwarding information, the data forwarding information comprising a corresponding relationship between multi segment pseudo wire (MSPW) information and forwarding information about an MSPW protection link group or other forwarding information about the MSPW other than the forwarding information about the MSPW protection link group (101); the SPE receiving a service message, the service message carrying the MSPW information (102); the SPE searching the forwarding information about the MSPW protection link group or other forwarding information about the MSPW other than the forwarding information about the MSPW protection link group (103); and the SPE performing label encapsulation and forwarding according to the searched forwarding information about the MSPW protection link group or other forwarding information about the MSPW other than the forwarding information about the MSPW protection link group (104).

Description

technical field [0001] The present invention relates to network data communication technology, more specifically, a data forwarding processing method and an operator-side operator edge equipment (SPE). Background technique [0002] PWE3 (Pseudo Wire Emulation Edge-to-Edge, edge-to-edge pseudowire emulation) provides tunnels on the packet switching network (IP / MPLS) to simulate some services (such as FR (Frame Relay, frame relay), ATM Layer 2 VPN (Virtual Private Network (virtual private network) protocol, through which the traditional network and the packet switching network can be interconnected, so as to realize the sharing of resources and the expansion of the network. [0003] PWE3 is an extension of the L2VPN Martini protocol, which adds the MSPW (Multi Segment Pseudo Wires) function and expands the networking mode. MSPW means that there are multiple PWs between U-PE (provider edge device on the user side, also called user access device) and U-PE. The U-PE in multi-h...
