Abstract

The invention provides a method and a device for transmitting a link detection message. The method comprises steps: a link detection message is received; the link detection message is detected; according to the detected result, topological information is added to the link detection message, flooding towards other Openflow devices except a local Openflow device is carried out, or, the information is sent to a software defined network (SDN) controller. Through the technical scheme of the invention, the detection message sending quantity is reduced, the burden of the SDN controller is lessened, and resources and the bandwidth of the SDN controller are saved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for transmitting link detection messages. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new network innovation architecture. Its core idea is to separate the control plane of network equipment from the forwarding plane, realize flexible control of network traffic, and provide a good platform for core network and application innovation. [0003] In order to obtain the network topology, the SDN controller sends an Openflow message that encapsulates an LLDP (LinkLayerDiscoveryProtocol, Link Layer Discovery Protocol) message to the source device (if there is no special description, the device described later in the present invention is an Openflow device), and the The LLDP packet carries the source device ID and the source port ID. The source device parses the LLDP message from the Openflow message, and sends t...
