Problems solved by technology

[0007] The above-mentioned message forwarding process based on the existing VPLS technology needs to rely on the MAC address table. If the user needs direct point-to-point access between multiple access sides (especially non-adjacent), it must additionally lease a virtual line and use VLL technology for Interconnection, that is, the existing VPLS network cannot support point-to-point subscriber line communication

Embodiment 1

[0026] This embodiment describes the implementation of user-dedicated line communication between ACs connected to the same PE device under any VSI.

[0027] In this embodiment, a local dedicated line group is first configured on the PE device, and its members are ACs corresponding to two local CEs (Custom Edge, user edge network equipment) that need to communicate in a user dedicated line mode. Forward packets to each other to form a dedicated user line.

[0028] Specifically, two ACs can be created in the VPLS instance of the control plane, and set as member ACs of the same local leased line group (called leased line ACs). The above configuration can be done through static configuration.

[0029] For example, for figure 1As shown in the VPLS network architecture, if CE10 and CE12 connected to PE1 need to use dedicated subscriber line to communicate, among them, CE10 is connected to PE1 through AC1, and CE12 is connected to PE1 through AC2, then configure AC access in VSI on...

Embodiment 2

[0057] This embodiment describes an implementation manner of realizing user-dedicated line communication between ACs connected to different PE devices under any VSI.

[0058] In this embodiment, firstly, the dedicated line groups are respectively configured on the PEs connected to each AC in the dedicated line group.

[0059] For example, for image 3 As shown in the VPLS network architecture, if CE10 connected to PE1 and CE40 connected to PE4 need to use dedicated subscriber line to communicate, among them, CE10 is connected to PE1 through PE1's local AC1, and CE40 is connected to PE2 through PE2's local AC2. When configuring AC access in the VSI, perform the following configurations:

[0060] vsi vsi1 static / / Create a VPLS instance named vsi1

[0061] pwsignal ldp / / Specify the signaling protocol of VPLS as LDP

[0062] vsi-id 500 / / Specify the ID of the VPLS instance as 500

[0063] peer 4.4.4.4 / / Specify VPLS peer PE4

[0064] peer 3.3.3.3 / / Specify the VPLS peer PE3

Abstract

The invention discloses a user private line communication method and equipment used in a VPLS (Virtual Private LAN (Local Area Network) Service) network, and the method equipment disclosed by the invention are applied to a service provider edge (PE). The method comprises: creating a virtual forwarding instance and setting access circuits (ACs) and opposite-end equipment which belong to the virtual forwarding instance by the service PE; configuring at least two ACs in the virtual forwarding instance into a private line group, and generating a private line group forwarding table associated with the virtual forwarding instance and the private line group, wherein the private line group forwarding table comprises an interface corresponding to each AC in the private line group; receiving an Ethernet message; analyzing the AC by use of the input interface for the Ethernet message and the associated virtual forwarding instance so as to determine the private line group to which the AC belongs; searching the associated private line group forwarding table according to the virtual forwarding instance and the private line group to which the AC belongs; and forwarding the Ethernet message through the interfaces corresponding to the other ACs in the searched private line group forwarding table. By adopting the user private line communication method and equipment disclosed by the invention, point-to-point user private line communication can be realized in the VPLS network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for user dedicated line communication in a VPLS network. Background technique [0002] MPLS L2VPN provides Layer 2 VPN (Virtual Private Network, virtual private network) services based on MPLS (Multi Protocol Label Switching, multi-protocol label switching) network, enabling operators to provide different data link layers based on a unified MPLS network Layer 2 VPN, including ATM (Asynchronous Transfer Mode, Asynchronous Transfer Mode), FR (Frame Relay, Frame Relay), VLAN (Virtual Local Area Network, Virtual Local Area Network), Ethernet (Ethernet), PPP (Point-to-Point Protocol, peer-to-peer protocol), etc. MPLS L2VPN includes two technologies: VPLS (Virtual Private LAN Service, virtual private LAN service) and VLL (Virtual Lease Line, virtual leased line). [0003] VPLS is a technology that provides virtual private Ethernet bridging domain...
