The present invention provides a network system and a network operation method, wherein each switch is instructed to send the basic information message thereof to a controller, the controller is instructed to obtain the network topology of the network system on the basis of a shortest routing algorithm, and to generate a corresponding link state database; the controller generates a weighted directed map according to the link state database, and generates a corresponding minimum spanning tree according to the weighted directed map; when receiving a data message, a switch determines whether the data message matches a flow table: if so, forward the data message according to an execution action of the flow table; and if not, send the data message to the controller; the controller inquires for the corresponding minimum spanning tree to obtain a forward route thereof, and then forwards the data message correspondingly. Configurations for all the switches of the present invention are concentrated on the controller, and network operations are largely executed by the controller, which can streamline network configuration and management, and improve network operation efficiency.
Description
technical field [0001] The invention relates to the field of electronic communication, in particular to a network system and a network operation method. Background technique [0002] The traditional OSPF (Open Shortest Path First, Open Shortest Path First) is an interior gateway protocol used for routing decisions within a single autonomous system, and it is a link-state based routing protocol. The OSPF protocol is distributed and the configuration is relatively complicated. Due to the complexity of network area division and network attributes, network analysts must have a high level of network knowledge to configure and manage OSPF networks. OSPF needs to exchange many kinds of LSA (Link-State Advertisement, link state broadcast) messages, which is relatively complicated and takes up resources. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a network system and a network...
