Abstract

The invention provides a discovery and real-time display system and method for an SDN (Software Defined Network) network topology. The method comprises the following steps that: after openflow switches are added into an SDN network, a connection relation acquisition module acquires port connection information among the openflow switches based on a protocol mechanism between an SDN controller and the openflow switches; when one openflow switch leaves the SDN network, the connection relation acquisition module updates corresponding port connection information; when a browse requester needs to browse the SDN network topology, a providing module sends a browse request to the connection relation acquisition module based on a second interface provided by a second interface module and a first interface provided by a first interface module; the connection relation acquisition module feeds back corresponding port connection information based on the received browse request; and the providing module provides the received port connection information for the browse requester in order to realize real-time perception and real-time display of network equipment.

Description

technical field [0001] The present invention relates to the field of SDN networks, in particular to a system and method for discovering and real-time presentation of SDN network topology. Background technique [0002] Software Defined Network (SDN) is a new innovative network architecture. Its core technology, OpenFlow, realizes flexible control of network traffic by separating the control plane of network equipment from the data plane. The innovation provides a good platform. [0003] The main purpose of network topology discovery is to obtain and maintain the existence information of network nodes and the connection relationship information between network nodes, and draw the entire network topology map on this basis, so that network managers can analyze the network topology based on the topology map. Faulty nodes can be quickly located. [0004] Under the existing network architecture, LLDP (Link Layer Discovery Protocol, Link Layer Discovery Protocol) provides a standa...
