Data processing method and apparatus for SDN Mobile Ad-Hoc Network

Abstract

The embodiment of the invention provides a data processing method and apparatus for SDN (Software Defined Networking) Mobile Ad-Hoc Network, being able to acquire the latest connection state between a controller and a switch. The data processing method for SDN Mobile Ad-Hoc Network includes the steps: performing self-learning on a data message to be processed and constructing a first flow entry; judging whether a flow entry being identical to a matching domain of the first flow entry exists in a disaster backup flow table; if so, deleting the flow entry being identical to the matching domain of the first flow entry and adding the first flow entry in the disaster backup flow table; and if not, adding the first flow entry in the disaster backup flow table; judging whether the data message to be processed matches the first flow entry added in the disaster backup flow table; if so, according to the first flow entry in the disaster backup flow table, processing the data message; and if not, according to the default flow entry, processing the data message. Therefore, the data processing method and apparatus for SDN Mobile Ad-Hoc Network can reduce the fault recovery time when a controller malfunctions, and can improve the reliability and stability of the network.

Description

technical field [0001] The present invention relates to the technical field of wireless communication network design, in particular to a data processing method and device for an SDN mobile ad hoc network. Background technique [0002] Ad Hoc network is a kind of centerless wireless network, which has the advantages of self-organization and rapid deployment, so it is widely used in many fields such as military, vehicle network, disaster rescue and smart city. However, the Ad Hoc network is a distributed network structure, its nodes are composed of mobile hosts, and all nodes are in the same position, so it lacks the whole network view and centralized control, and has insufficient flexibility for resource scheduling. Software Defined Networking (SDN) technology logically divides the network into a control plane and a data plane. The control and forwarding strategy of the network is deployed centrally by the controller at the control plane, and the forwarding device focuses on ...

Problems solved by technology

But OVS is in "fail safe mode", when the controller is disconnected, it takes 10s to obtain the connection status, so the fault recovery time also takes about 10s, so the fault recovery time is long

[0007] It can be seen that no matter what kind of working mode OVS is, in the case of controller failure, the recovery time of communication failure is still long, which seriously affects the reliability and stability of the network.
