Abstract

The embodiment of the invention provides a topology pruning method and device for a ring network and a virtual switch. The method is applied to a target virtual switch included in a ring network, the ring network is composed of a plurality of virtual machines and a plurality of virtual switches, the ports of the virtual machines and the virtual switches are connected in a set mode, the target virtual switch is any one of the virtual switches, and the target virtual switch comprises a first port. The method comprises the following steps: receiving a first BPDU message sent by a second port of a first virtual machine through a first port, wherein the first BPDU message comprises an MAC address of the second port; if the MAC address of the first port is empty, setting the MAC address of the first port as the MAC address of the second port; and based on the set MAC address of the first port, executing a spanning tree protocol to complete topology pruning of the ring network, thereby solving the network storm.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a ring network topology pruning method, device and virtual switch. Background technique [0002] Nowadays, with the development of network technology, data transmission becomes faster and faster, which greatly facilitates users to obtain data. The development of network technology benefits from the mature application of virtual network, which can flexibly arrange network topology. However, due to the poor layout of some network topologies, a ring network is formed, so that data is always transmitted in the closed-loop network, causing network storms, consuming virtual switch resources, and even causing network paralysis. [0003] At present, the Spanning Tree Protocol (STP) protocol helps to solve the ring network. Its operation mechanism is to discover the loop in the network by broadcasting node information, and selectively block a certain port, and finally the ring net...
