Embodiment Construction

[0024] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0025] See image 3 , image 3 It is a network topology diagram that supports Layer 2 interconnection of data center sites in the embodiment of the present invention. Only the edge devices of each site are drawn. The internal topology of the site is not the focus of the present invention, so it is not drawn in the figure. image 3 In, sites A, B, C, D, and E access the core network through their respective edge devices 1, 2, 3, 4, and 5; in addition, neighbor servers are deployed in the core network to record current online Information about each data center site. Here, the neighbor server can also be deployed on an edge device. It should be noted that the site described in this application document is also a data center site.

Abstract

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.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to a topology construction method and device supporting two-layer interconnection of data centers. Background technique [0002] The data center is the center of providing various services, and the center of data processing, data storage and data exchange. In order to provide better services, providers usually deploy multiple data centers in remote locations to achieve load sharing and high reliability, and to realize the free migration of virtual machines between data centers. Since the virtual machine migration process is transparent to users and the IP address cannot be changed, it is necessary to realize Layer 2 network interconnection between data centers distributed in different places. [0003] Data center interconnection needs to meet the following basic requirements: each site is independent of each other, and the topology and faults within the site do not a...
