Abstract

The embodiment of the invention discloses a flooding processing method and apparatus. The flooding processing method comprises: a controller receives a data packet reported by a switch connected with a source host; the controller retrieves whether a destination address of the data packet exits in a local device physical address MAC address list; if not, the controller obtains a destination port that is a port of a switch connected with a target host, wherein the target host is another host different from the source host; and the controller uses the destination port as a destination address to generate a routing table and the routing table is sent to the switch connected with the source host, so that the switch connected with the source host forwards the data packet according to the routing table. According to the invention, the methods and apparatuses are suitable for the communication system field.

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 forwards strictly based on the forwarding table; the switch provides an interface API (Application Programming Interface, application programming interface) for the controller to control; the switch and the controller follow a certain protocol. [0003] In the SDN network, the initial routing table of the switch is empty, and when the receive...
