Abstract

The invention discloses (an) SDN based fault handling method, device and equipment, relates to the technical field of network, solves the problem in handling conflict of flow table items without influence on APP functions, and avoids SDN faults caused by conflict of the flow table items. The method comprises that when it is detected that a new network application is online in the SDN, the new network application is registered, and association between the new network application and an existing network application in the SDN is determined; when the network application issues a new flow table, whether a flow table item of the new flow table conflicts with a flow table item of a present flow table of a corresponding to-issue device is detected; if YES, the flow table item of the new flow table is reassembled according to the association to eliminate the conflict; and the new flow table after reassembling of the flow table item is issued to the device to issue. The method, device and equipment can be used to handle the SDN fault caused by conflict of the flow table items.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a fault handling method, device and equipment based on an SDN network. Background technique [0002] Software Defined Network (SDN) is a new network innovation architecture of Emulex network and a way to realize network virtualization. Different from the traditional network architecture, its core technology is to separate the control plane and data plane of network equipment through the southbound interface protocol of the controller. [0003] Traditional networks need to use hardware devices to implement forwarding control, while SDN networks generate forwarding policies through network applications (Application, APP) and send them to forwarders through southbound interface protocols, instead of controlling forwarding policies through hardware. Due to the diversity of network application APPs, the dependencies between APPs are very complex. When an APP generates a ne...
