Control server, control server application system and control server application method

Abstract

The present invention provides a control server, a control server application system and a control server application method. The control server is connected with a plurality of switches, the switches can be connected via paths, and each switch can be connected with one or a plurality of terminal devices, thereby forming a large two-layer network. The control server comprises a network construction module, a route calculating module, an address mapping module, a flow management module, a flow table updating module and an ARP processing module. By the uniform management and control of the control server to the whole network switching equipment, the route information of the large two-layer network is configured rapidly, and the network convergence time is reduced. By using the controller to processing an addressing request, the broadcast addressing requests in the network are reduced, and the transmission delay is also reduced. Meanwhile, the management and control of the system are mainly concentrated in the control server, so that the control server just needs to be configured for the updating and modification of the whole network route, and the execution of the management measures is simplified.

Description

technical field [0001] The invention relates to the field of computer network, in particular to a system and method for controlling a server and its application. Background technique [0002] In the traditional data center server area network design, the scope of the Layer 2 network is usually limited below the network access layer to avoid a large-scale Layer 2 broadcast domain. With the development of virtualization technology, virtualization brings not only the improvement of server utilization to the data center, but also the change of network architecture. Specifically, virtual machine live migration, a companion technology of virtualization technology, has been widely used in data centers. However, virtual machine migration requires that the IP and MAC addresses of the virtual machine remain unchanged before and after the migration, which requires that the network before and after the virtual machine migration be in the same Layer 2 domain. As customers require that ...
