Problems solved by technology

[0004] When a BEB device sends MAC-in-MAC encapsulated MAC-in-MAC packets to other BEB devices in multicast mode, the multicast traffic in the PBB network or SPBM network will be too much, causing a relatively large impact on the backbone network. Impact, and a large number of BEB devices receive MAC-in-MAC packets that do not need to be received

Embodiment approach

[0071] Based on this embodiment, BEB device 1 adds the B-MAC and I-ISD1 of BEB device 2 to the B-MAC entry, and adds the B-MAC and I-ISD1 of BEB device 3 to the B-MAC entry. By analogy, the B-MAC and I-ISD1 of BEB device 95 are added to the B-MAC entry; in addition, BEB device 1 adds the B-MAC and I-ISD2 of BEB device 96 to the BEB device library, and so on, adding The B-MAC and I-ISD2 of the BEB device 100 are added to the BEB device library.

[0072] By counting the correspondence between B-MAC and I-ISD1 recorded in the B-MAC entry, BEB device 1 knows that the number of B-MACs corresponding to I-ISD1 is 94, and then knows the number of BEB devices added to service instance 1 is 95 (including BEB device 1 itself); by counting the corresponding relationship between B-MAC and I-ISD2 recorded in the BEB device library, BEB device 1 knows that the number of B-MACs corresponding to I-ISD2 is 5, and then learns to join The number of BEB devices to service instance 2 is 5.

Abstract

The invention discloses a message transmission method and equipment in an MAC-in-MAC network. The method comprises the steps that BEB devices receive assigned characteristic messages from a user network and determine service instances corresponding to the assigned characteristic messages, and the number of the BEB devices added into the service instances is obtained; the BEB devices determine whether the assigned characteristic messages are sent through a multicast mode or a unicast mode according to the number of the BEB devices added into the service instances; when the assigned characteristic messages are sent through the multicast mode, the BEB devices carry out MAC-in-MAC packaging on the assigned characteristic messages on the basis of the multicast mode and send the assigned characteristic messages after the MAC-in-MAC packaging is carried out in the multicast mode; when the assigned characteristic messages are sent through the unicast mode, the BEB devices carry out MAC-in-MAC packaging on the assigned characteristic messages on the basis of the unicast mode and send the assigned characteristic messages after the MAC-in-MAC packaging is carried out in the unicast mode. According to the message transmission method and equipment, multicast flow in a backbone network can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message transmission method and device in a MAC-in-MAC (MAC (Media Access Control, Media Access Control) address nesting) network. Background technique [0002] MAC-in-MAC is a Layer 2 VPN (Virtual Private Network, virtual private network) technology, and its backbone network includes BEB (Backbone Edge Bridge, backbone network edge bridge) equipment and BCB (Backbone Core Bridge, backbone network core bridge) equipment. The BEB device is responsible for MAC-in-MAC encapsulation of packets from the user network and forwarding to the backbone network; decapsulation of MAC-in-MAC packets from the backbone network and forwarding to the user network. The BCB device is responsible for forwarding MAC-in-MAC packets according to B-MAC (Backbone MAC, backbone network MAC) and B-VLAN (Backbone Virtual Local Area Network, backbone virtual local area network). When the BE...
