Constructing a network enabling layer-2 interconnection of data centers

摘要

A method for constructing a network enabling layer-2 interconnection of data centers includes: a current data center registers at a neighbor server when the current data center gets online, obtains information of all registered data centers, generates a virtual bridge port for each registered data center; after the current data center comes online, the current data center obtains information of all newly registered data centers according to a pre-set rule, generates a virtual bridge port for each newly registered data center; establishes a tunnel to each registered data center by using the virtual bridge port corresponding to the registered data center, and transmit data via the tunnel.

1. A method for constructing a network enabling layer-2 interconnection of data centers, comprising:
registering, by an edge device of a first data center, information of the first data center, which includes an IP address of the first data center, at a neighbor server; obtaining, by the edge device, information of a second data center from the neighbor server; generating a virtual bridge port for the second data center based on the information of the second data center; configuring a tunnel encapsulation entry corresponding to the virtual bridge port in a tunnel encapsulation mapping table, wherein the tunnel encapsulation entry includes the virtual bridge port, an IP address of the second data center, the IP address of the first data center; and establishing, by the edge device, a tunnel with the second data center according to the tunnel encapsulation entry corresponding to the second data center, and transmitting data via the tunnel.
