Abstract

The embodiment of the present invention discloses a flooding processing method and device. The method includes: first, the controller receives the data packet reported by the switch connected to the source host; Retrieve whether there is the destination address of the data packet, if there is no destination address of the data packet, the controller obtains the destination port, the destination port is the port of the switch connected to the target host, and the target host is different from other hosts other than the source host; finally, the controller uses the destination port as the destination address, generates a routing table, and sends the routing table to the switch connected to the source host, so that the A switch connected to the source host forwards the data packet according to the routing table. The invention is applicable to the field of communication systems.

Description

technical field [0001] The invention relates to the field of communication systems, in particular to a topology classification method and device, and a flooding processing method and device. Background technique [0002] In a traditional computer network, each switch can only obtain information about adjacent switches, and there is no global network view for each switch. A network based on SDN (Software Defined Network, software-defined network) technology is one of the important trends in future network development. The core idea of ​​SDN is to separate the control plane of network equipment from the data forwarding plane. The switch is forwarded strictly based on the forwarding table; the switch provides an interface API (Application Programming Interface, application programming interface) for the controller to control; a certain protocol is followed between the switch and the controller. [0003] In the SDN network, the initial routing table of the switch is empty, and...
