Embodiment Construction

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

[0025] see image 3 , image 3 It is a network topology diagram supporting Layer 2 interconnection of data center sites according to the embodiment of the present invention. Only the edge devices of each site are drawn, and 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, a neighbor server is also deployed in the core network to record the 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 mentioned in this application document is also a da...

Abstract

The invention provides a topology construction method and a topology construction device supporting the layer 2 interconnection of data centers. The method comprises that: when online, a current site is registered in a neighbor server, acquires the information of each registered site and generates virtual bridging ports corresponding to each registered site; after being registered in the neighbor server, the current site acquires the information of all the newly registered sites according to preset rules, and generates the virtual bridging ports corresponding to each newly registered site; and the current site establishes channels with each registered site by the virtual bridging ports corresponding to each registered site for data transmission. By the method and the device, the sites can be automatically discovered.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for constructing a topology supporting Layer 2 interconnection of data centers. Background technique [0002] The data center is the provider center of 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 different places to achieve load sharing and high reliability, and 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 implement Layer 2 network interconnection between data centers distributed in different places. [0003] The interconnection of data centers needs to meet the following basic requirements: each site is independent of each other, and the topology and faults in the site do ...
