Abstract

The present invention provides an SDN-based host discovery method and system. The method includes: 1) the controller obtains switch topology information of the entire network; broadcast tree, and according to the generated broadcast tree to configure and issue relevant flow tables for each switch; 3) The switch forwards the ARP host search message according to the issued flow table, so that the ARP host search message can follow the broadcast The tree is propagated throughout the network to efficiently discover destination hosts. The present invention frees the controller from the heavy host discovery task and turns it over to each switch, which only reduces the workload of the controller and makes it relatively more capable to be responsible for other management and control tasks in the SDN network. Moreover, the host search message can be quickly spread to the whole network in a radiation mode along the switch-level broadcast tree, thereby realizing efficient host discovery.

Description

technical field [0001] The invention belongs to the technical field of network broadcasting, and in particular relates to an SDN-based host discovery method and system. Background technique [0002] With the development of virtualization technology, big data and cloud computing, whether it is in IT, Industry 4.0, city management, or in the fields of economy, entertainment, education, etc., it is required that the large second-tier network of the data center can accommodate tens of millions or even Capability of hundreds of millions of hosts. Therefore, how to implement good management on a large number of hosts, especially how to quickly and effectively realize the discovery and search of the destination host will be very difficult. At this time, an efficient host discovery method and system will appear very important. [0003] However, many existing technologies (for example, G.Singh and A.J.Bernstein, "A Highly Asynchronous Minimum Spanning Tree Protocol," Distributed Co...
