Abstract

The invention discloses a network fault automatic detecting system based on SDN; the system comprises an SDN controller and SDN switches; multiple SDN switches are arranged; and the SDN controller is in control connection with the SDN switches; and the detecting method comprises the following steps: step 1, connecting the network switches by the SDN controller; step 2, obtaining and storing a network initial topology by the controller; step 3, regularly sending detection messages packet-out by the controller; step 4, sending back packet-in by the switches and forwarding; step 5, regularly calculating the new network topologies by the controller; step 6, comparing the new initial topologies by the controller; step 7, judging according to a comparison result in the step 6; and step 8, marking a fault point and alarming. The system and the method disclosed by the invention have the following beneficial effects: 1, the network fault is automatically found in real time; 2, the fault point is found accurately; 3, the system and the method help a network administrator to position a problem quickly and accurately; and 4, the user experience is good and the user satisfaction is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of software-defined networks, in particular to a system and method for automatic detection of network faults based on SDN. Background technique

[0002] At present, in server virtualization, virtual machines are sometimes automatically migrated online according to business needs. But after migration, it needs to be reconfigured on the new virtual switch. The existing SDN solution has no automatic switch migration solution, and the disadvantages are as follows: 1. The new switch configuration needs to be manually configured and the old switch configuration is deleted; 2. It is easy to make mistakes.

[0003] Therefore, designing a new system and method for automatic detection of network faults is a technical problem that needs to be solved. SUMMARY OF THE INVENTION

[0004] The purpose of the present invention is to provide a system and method for automatic detection of network faults based on SDN, so as ...
