Abstract

The invention discloses a hybrid SDN (Software Defined Networking) switch by utilizing a dynamic migration technology, relating to an SDN switch technology. The hybrid SDN switch mainly comprises switch hardware, an Linux operating system, a switch chip SDK (Software Development Kit), a traditional switch protocol module and an SDN module, wherein the switch hardware is traditional switch hardware; the traditional switch protocol module and the SDN module form a switch software level; furthermore, the SDN module comprises two parts including an OpenFlow module and an SDN controller; a virtual machine is started in the switch; the SDN controller is operated in the virtual machine; and the SDN controller can be dynamically migrated into a server along with the virtual machine according to requirements. According to the invention, the resources and the computing power of a processor in the switch are sufficiently utilized; therefore, the function flexibility of the switch can be greatly improved; and the high availability of the SDN switch can be ensured.

Description

technical field [0001] The invention relates to SDN switch technology, in particular to a hybrid SDN switch using dynamic migration technology. Background technique [0002] SDN switch technology has developed rapidly in recent years, but it is basically at the software level. In terms of the specific implementation of SDN switches based on protocols such as OpenFlow, there has been no unified model, especially in terms of integration with traditional switches. A practical method is needed to support future technologies while protecting users' existing investments and being compatible with applications under traditional switching architectures. [0003] At the same time, in terms of virtualization applications, the server device is basically used as the carrier of the virtualization application, and the server and the switch are still used independently as two completely different devices. How to realize the integration of switches and servers with the help of SDN and virtu...
