Network link quality monitoring method and device

Abstract

The invention discloses a network link quality monitoring method. The method comprises the following steps: acquiring address information of each network node in a specified routing path correspondingto a specified virtual router (vRouter); establishing monitoring network connection between a preset virtual computing node and the virtual router; and according to the address information of each network node, sending a packet internet grope (PING) to each network node from the preset virtual computing node through the monitoring network connection to obtain a network link quality parameter corresponding to each network node. The invention further discloses a network link quality monitoring device, a storage medium and an information processing device.

Description

technical field [0001] The present invention relates to software defined network (SDN, Software Defined Network) technology, and in particular to a method and device for monitoring network link quality. Background technique [0002] SDN is a new type of network innovation architecture. Its core idea is to separate the control plane of network equipment from the forwarding plane to achieve flexible control of network traffic and provide a standard and open application programming interface (API, Application Programming Interface) , in order to realize the flexible orchestration requirements of various business platforms on the network. [0003] More and more data center networks use SDN technology to improve network resource utilization and deployment efficiency, and reduce network maintenance costs. Through SDN virtualization and overlay network (overlay) technology, a multi-tenant and multi-routing business model can be realized, and secure and flexible second- and third-l...

However, BFD cannot provide measurement data on link packet loss and link delay;

[0006] 2. The Y.1731 Ethernet Operation Administration and Maintenance (OAM, Operation Administration and Maintenance) monitoring standard issued by the ITU organization can monitor the transmission quality of network links such as on-off, delay and packet loss of single-layer network (Underlay) links ; but in China, the overlay network cannot monitor the transmission quality of the last mile network link from the user access side to the network element, and the forwarding of Layer 2 multicast to the outside of the data center needs to rely on traditional routers to support connectivity fault management (CFM, Connectivity Fault Management) Management) feature, corresponding to north-south monitoring is difficult to cover
