VXLAN tunnel topology monitoring method and device, equipment and storage medium

Abstract

The invention discloses a VXLAN tunnel topology monitoring method, device and equipment and a storage medium, and the method comprises the steps: collecting OF equipment information, tunnel port configuration and VXLAN network tunnel information through an SDN controller, and building a VXLAN logic topology according to the OF equipment information, the tunnel port configuration and the VXLAN network tunnel information; controlling each OF device to send a unidirectional monitoring message regularly according to the VXLAN logical topology, and starting a timer to wait for a return packet of the monitoring message; analyzing a return packet of the monitoring message, detecting the time delay between the SDN controller and the OF equipment, and updating the time delay monitoring data of each side of the VXLAN logical topology; therefore, the tunnel topology monitoring can be realized by using a common protocol layer tunnel detection technology; the adaptation and butt joint of the SDN controller to hardware network equipment of various non-OF protocols in the SDN network are avoided, and the smooth detection and monitoring of the tunnel topology in the SDN network are ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a VXLAN tunnel topology monitoring method, device, equipment and storage medium. Background technique [0002] Now there are two ways of VXLAN tunnels, static virtual extensible local area network (Virtual Extensible Local Area Network, VXLAN) and Ethernet virtual private network virtual extensible local area network (Ethernet Virtual Private Network VXLAN, EVPN VXLAN); in the current software-defined network ( In the Software Defined Network (SDN) networking environment, due to the requirements for the capabilities of the devices in the network, standard DC (Openflow, OF) devices and non-OF traditional devices appear together to form a static VXLAN tunnel network, which is called hybrid SDN networking. [0003] In a hybrid SDN network, the SDN controller centrally controls the standard OF equipment, and the non-OF traditional equipment uses the protocol stack as t...
