Problems solved by technology

[0003] In the prior art, both the SPB network and the PBB network realize the normal forwarding of the user-side traffic, but the backup of the user-side traffic has not yet been realized, that is, the SPB network and the PBB network do not provide related technologies for backing up the user-side traffic. As a result, it is impossible to effectively monitor the user-side traffic

Embodiment 1

[0048] An embodiment of the present invention provides a traffic backup method, and describes the connection between a monitoring CE device and a monitored CE device connected to the same BEB device. In this embodiment, the monitoring CE device is connected to the monitoring server and the BEB device respectively, and the monitored CE device is connected to the monitored host and the BEB device respectively. by figure 1 It is a schematic diagram of an application scenario of the embodiment of the present invention, Host11 is a monitoring server, Host10 is a monitored host, CE11 is configured as a monitoring CE device, and CE10 is configured as a monitored CE device.

[0049] Further, the AC (Attachment Circuit, access link) between the monitored CE device and the BEB device is divided into two types: the monitored AC and other ACs. The monitored AC is used to transmit the packets corresponding to the monitored host, and the other AC is used to transmit messages corresponding ...

Embodiment 2

[0093] An embodiment of the present invention provides a traffic backup method, and describes the connection between a monitoring CE device and a monitored CE device connected to different BEB devices. In this embodiment, the monitoring CE device is connected to the monitoring server and the first BEB device respectively, and the monitored CE device is connected to the monitored host and the second BEB device respectively. by image 3 It is a schematic diagram of the application scenario of the embodiment of the present invention, Host11 is a monitoring server, Host20 is a monitored host, CE11 is configured as a monitoring CE device, and CE20 is configured as a monitored CE device; in addition, BEB1 is the first BEB device, and BEB2 is the second BEB equipment.

[0094] Further, the AC between the monitored CE device and the second BEB device is divided into two types: the monitored AC and other ACs. The monitored AC is used to transmit messages corresponding to the monitored...

Embodiment 3

[0158] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a backbone network edge bridge BEB device, which is applied to a network including a monitoring user network edge CE device, a monitored CE device, and the BEB device. The monitoring CE equipment, the monitored CE equipment is connected to the BEB equipment, such as Figure 5 As shown, the BEB equipment specifically includes:

[0159] The maintenance module 11 is used to configure the Agent strategy, and maintain the monitoring media access control MAC table and the common MAC table; the Agent strategy is used to make the BEB device receive the message sent by the monitored CE device through the monitored access link AC, The packet is forwarded to the monitoring CE device through the monitoring AC; the monitoring MAC table is used to record the correspondence between the MAC address of the monitored host and the monitored AC; the ordinary MAC table is used to re...

Abstract

The invention discloses a traffic backup method and equipment, comprising: when a BEB device receives a first service message, it matches an Agent policy, and forwards the first service message to a monitoring CE device through a monitoring AC; When receiving the first service message returned by the monitoring CE device, it sends the first service message to the destination device; when the BEB device receives the second service message, it uses the MAC address of the monitored host to query the ordinary MAC table, Determine the outgoing port as the monitoring AC, and forward the second service message to the monitoring CE device through the monitoring AC; when the BEB device receives the second service message returned by the monitoring CE device, it uses the MAC address of the monitored host to query the monitoring MAC address. The output port is determined as the monitored AC, and the monitored AC forwards the second service message to the monitored CE device, and the monitored CE device forwards the second service message to the monitored host. In the embodiment of the present invention, the real-time backup of user-side traffic is realized, and the user-side traffic can be effectively monitored.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a traffic backup method and equipment. Background technique [0002] PBB (Provider backbone bridge, operator backbone bridge) network and SPB (Shortest PathBridging, shortest path bridge) network both define the frame structure of double-layer MAC (Media Access Control, media access control) addresses, and adopt traditional MAC switching. The PBB network forwards user-side traffic based on the operator's MAC address instead of forwarding user-side traffic based on the user's MAC address. The SPB network is a further extension of the Spanning Tree Protocol, aiming to build a large, flat, non-blocking Layer 2 network. [0003] In the prior art, both the SPB network and the PBB network realize the normal forwarding of the user-side traffic, but the backup of the user-side traffic has not yet been realized, that is, the SPB network and the PBB network do not provide r...
