Method and device for monitoring CE (Client Equipment)

Abstract

The invention relates to a method and a device for monitoring CE (Client Equipment). The method comprises the following steps that when an ED (Edge Device) receives a message from a Client CE side, the ED sends the message to a corresponding Monitor CE, and the Monitor CE forwards the message to a Monitor device; when the ED receives the message which is from a Normal CE side and of which the target MAC (Media Access Control) address is an MAC address of a host suspended by Client CE, the ED sends the message to the corresponding Monitor CE, and the Monitor CE forwards the message to the Monitor device; and when the ED receives the message from the Monitor CE side, the ED forwards the message according to the target MAC address of the message. In the method and the device, the traffic of the Client CE is monitored on the premise of not changing network topology and not influencing the conventional client traffic.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and equipment for implementing CE monitoring. Background technique [0002] EVI (Ethernet Virtual Interconnection, Ethernet Virtual Interconnection) is an Ethernet interconnection technology, which is mainly used for the interconnection of user data centers in multiple different regions. EVI implements VLAN (Virtual Local Area Network, virtual local area network) expansion functions between different sites. These expanded VLANs form independent EVI instances. EVI instances are identified by Network ID (identification), and are numbered globally and on a certain device. The intra-VLAN forwarding of different EVI instances is isolated from each other. [0003] The current EVI instance network only realizes the normal forwarding of user-side traffic, and has not yet realized centralized monitoring of user-side traffic. It cannot target the traffic of some CE (Customer Ed...

AI Technical Summary

Problems solved by technology

[0006] In the EVI networking, there is no effective method to track and monitor the traffic of some specific user CE devices. Although the Hub-Spoken networking can realize the centralized forwarding and monitoring of traffic, the existing network needs to be restructured. , which affects the original user traffic forwarding, and at the same time, it cannot flexibly monitor some CE devices, and can only process all traffic, resulting in a waste of resources
