Virtual networking network topology discovery method and device

Abstract

The invention provides a virtual networking network topology discovery method and device. A topology management module is deployed on a physical device with virtual networking, and the topology management module is used for obtaining topology connection relation data in virtual networking, carrying the topology connection relation data in LLDP messages and transmitting the topology connection relation data to an external physical network device connected with the physical device. Thus, the topology connection relation of virtual networking can be transmitted to equipment in a physical network, and topology discovery of virtual networking is achieved.

Description

technical field [0001] The present application relates to network communication technology, in particular to a method and device for discovering network topology in virtual networking. Background technique [0002] The so-called virtual networking refers to virtualizing virtual machines (VM: Virtual Machine), virtual switches (Vswitch) and other devices in a physical device through virtualization technology, and connecting these virtual devices to form a virtual network. Local area network, denoted as virtual networking, figure 1 A schematic diagram of a virtual networking on a physical device is shown. [0003] Virtual networking is "virtual", and, in virtual networking, there is no direct connection between VMs, and between VMs and external physical network devices connected to physical devices, which results in the topology applied to the physical network Discovery protocols such as Link Layer Neighbor Discovery Protocol (LLDP) and Simple Gateway Monitoring Protocol (SN...
