Abstract

The invention discloses a method for building an MAC (Media Access Control) address table and a provider edge device. In the method, a PE (Provider Edge Device) receives a first service message by a PW (Pseudo Wire) connected with the PE; when the first received service message is confirmed to be a specific-type message, the building of the address table entry of the source MAC address of the first service message is cancelled, wherein the specific-type message is an unknown unicast message, a multicast message or the broadcasting message of a non-free ARP (Address Resolution Protocol) message. According to the scheme provided by the embodiment of the invention, the amount of the address table entries built by the PE is reduced so as to reduce the volume of the MAC address table.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a method for establishing a MAC (Media Access Control, Media Access Control) address table and an operator edge device. Background technique

[0002] With the development of data communication technology and the emergence of cloud computing / distributed computing, computing power has also become a commodity. For example, it can be sold externally based on virtual machines. At this time, the data center is the physical carrier of such commodities. A data center (DC for short) is a facility consisting of computing systems, storage systems, communication systems, network equipment, environmental control systems (such as cooling systems and fire protection systems), security systems and other components. And by providing a large number of redundancy solutions to improve the reliability of the data center, such as power supply redundancy, communication connection redunda...
