Problems solved by technology

[0009] It can be seen that in the existing PBB network, if a private line connection is required, it can only be realized by creating a PBB instance for each private line connection, and only one AC accesses the PBB instance on the BEB device; For some switch products, the number of PBB instances is often limited. Therefore, when a large number of private line connections are required in the PBB network, the existing method of creating PBB instances cannot meet this networking requirement.

Embodiment 1

[0038] Example 1: Create a local user-dedicated line connection

[0039]Take the BEB1 device to create a local private line connection as an example. BEB1 creates two local private line ACs in a PBB instance, and specifies the binding relationship between the two local private line ACs to establish the two local private line ACs. local subscriber line connections between them. Such as Figure 4 It is a schematic diagram of connection of a local subscriber line created in Embodiment 1 of the present invention.

[0040] For example, the following configuration can be done on BEB1:

[0041] i-sid 4532 create / / Create a PBB instance, and specify the I-SID of the PBB instance as 4532;

[0042] i-sid 4532 name "XXXXXX" / / Comment on this PBB instance

[0043] i-sid 4532 b-vlan 300 / / Specify the outer encapsulation BVLAN for this PBB instance as 300

[0044] i-sid 4532 vp-ac ac1 gigabitethernet 1 / 1 vlan 1

[0045] / / Create a local private line A...

Embodiment 2

[0060] Embodiment 2: Create a remote user dedicated line connection

[0061] Take BEB1 and BEB3 to create two remote private line connections as an example. BEB1 creates a local private line AC and a remote private line AC corresponding to BEB3 in a PBB instance, and establishes a binding between the local private line AC and the remote private line AC. establish a relationship between them, and create a remote dedicated line connection between them; correspondingly, BEB3 creates a local dedicated line AC and a remote dedicated line AC corresponding to BEB1 in the PBB instance, and establishes a connection between the local dedicated line AC and the remote dedicated line AC. The binding relationship between the two, create a remote subscriber line connection between the two. The remote subscriber line ACs created on BEB1 and BEB3 should correspond to each other.

[0062] Such as Figure 5 It is a schematic diagram of a remote subscriber line connection created for Embodiment...

Abstract

The present invention provides a method and a Backbone Edge Bridge (BEB) device for realizing private line connection in an operator's Backbone Bridge (PBB) network, wherein the method includes: the BEB device creates one or more pairs of private line access in a PBB instance Link (AC), the dedicated subscriber line AC is the AC used to implement subscriber dedicated line connections in the PBB instance; specify the binding relationship between each pair of subscriber dedicated line ACs, and create a link between each pair of subscriber dedicated line ACs Dedicated line connection: the BEB device uses the dedicated line connection to forward and process the messages between each pair of dedicated line ACs. The invention can realize the user dedicated line connection in the PBB network.

Description

technical field [0001] The present invention relates to the technical field of PBB, in particular to a method and BEB equipment for realizing private line connection in a PBB network. Background technique [0002] The provider backbone bridge (PBB, Provider backbone bridge) network adopts the two-layer media access control (MAC-IN-MAC) standard defined by 802.1ah, which was born in response to the requirements of the Metropolitan Ethernet Network (MEN, Metropolitan Ethernet Network). In the service layering model of the MEN, the PBB network is located at the bearer position, and MAC tunnels are established at the network core to differentiate and isolate user services. [0003] Such as figure 1 It is a schematic diagram of a PBB network structure in the prior art, and the PBB network includes two types of equipment: a backbone edge bridge (BEB, Backbone Edge Bridge) equipment and a backbone core bridge (BCB, Backbone Core Bridge) equipment; wherein, [0004] The BEB device...
