Embodiment Construction

[0024] An SDN-based cross-data center communication method and network of the present invention will be further described in more detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 As shown, a kind of SDN-based cross-data center communication method of the present invention comprises the following steps:

[0026] Deploy and start the cross-domain gateway system, the cross-domain gateway system includes the first to Nth cross-domain gateways, each cross-domain gateway is connected to the data center and other cross-domain gateways;

[0027] Create a VxLAN tunnel from the data center to the cross-domain gateway; initialize the cross-domain gateway system and create a VxLAN tunnel from the cross-domain gateway to the data center; this VxLAN tunnel is centrally configured through the cross-domain network platform, making the management of the tunnel flexible. controllable.

[0028] According to different services, use the SDN controller to dist...

Abstract

The invention discloses a cross-data center communication method and a network system based on an SDN (Software Defined Network). According to the communication method, a network technique of the SDN is adopted, and automatic network arrangement management can be achieved. The gateway of an OF (Open Flow) protocol is supported, an SDN controller ODL is introduced, a VxLAN network of Overlay is achieved through the gateway, and inter-communication of L2 can be achieved. Flow table planning of the OF gateway is implemented through the ODL controller, the forwarding behavior of the gateway is controlled, and a lessee network is managed. According to the cross-data center communication method and the network system based on the SDN, cross-data central networks are isolated through lessees or business, communication of cross-data centers is optimized, dynamic, controllable and efficient management on communication of the cross-data centers can be achieved, and the communication speed can be increased greatly.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to an SDN-based cross-data center communication method and network system. Background technique [0002] With the development of the network and the explosive growth of the data volume, the status and role of the data center in the communication industry has shown unprecedented importance. With the rapid expansion of data center business logic and data scale, a single-node data center can no longer meet current needs. The deployment of multi-node data centers across regions has become mainstream. For data centers with multiple nodes across regions, system resources are dispersed and networks are isolated. In order to coordinate among nodes in the data center, integrate resources and optimize allocation, cross-data center traffic is the basis for meeting the above requirements. However, the traditional cross-data center communication method cannot flexibly build cros...
