Embodiment Construction

[0042] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose of the invention, the specific implementation and working principle of the routing control method of the OpenFlow controller proposed according to the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. illustrate.

[0043] Depend on figure 1 It can be seen that the routing control method of the OpenFlow controller provided by the present invention includes:

[0044] First, the OpenFlow controller checks whether the encoding policy of the session information on the OpenFlow switch already exists; specifically, the OpenFlow controller first collects the information data of the OpenFlow switch, and obtains the link to which the OpenFlow switch belongs and the change of the link to which the OpenFlow switch belongs situation and the session information on the OpenFlow switch; a...

Abstract

The invention relates to the technical field of routing control, and discloses a routing control method for an OpenFlow controller. The routing control method includes that the controller detects whether a session information coding strategy is available on an OpenFlow switch or not; a session information operating instruction is transmitted to the OpenFlow switch if the session information coding strategy is available; a session information coding strategy is designed if the session information coding strategy is unavailable; and finally, the coding strategy and corresponding forwarding behavior are distributed to the corresponding OpenFlow switch. The routing control method has the advantages that coding operation and decoding operation are designed for the OpenFlow switch via the OpenFlow controller, network coding is carried out for a network flow, and accordingly the network capacity is improved.

Description

technical field [0001] The invention relates to the technical field of route control, and is mainly applicable to a route control method of an OpenFlow controller. Background technique [0002] In the open OpenFlow network structure, the OpenFlow controller can centrally manage the network, and the OpenFlow switch can expand the data processing capability of the switch by customizing the processing method of the data flow. The two together form a set of network management operating system. [0003] Different from the traditional IP network, the OpenFlow network centralizes the flow processing strategy (control plane) of all switches to be designed on the controller, so that the routing control can be centrally designed. According to the interface provided by the open project nox, the centralized routing algorithm can be designed, and the common distributed routing engine can be directly transplanted to the controller side. [0004] There are many attempts in existing OpenFl...
