A kind of automatic testing method and device for the availability of giant system domain network

Abstract

The invention discloses an automatic test method for the usability of a giant system domain network. The steps of the method include: 1) when a test request is received, calculating the maximum link bandwidth of each link in the network and the maximum node bandwidth of each node; 2) each When the test task of a switch node is generated, select the source link and the destination link whose link maximum bandwidth matches each other, select the source computing node and the destination computing node respectively by the source link and the destination link, and set the test traffic mapping relationship; 3. ) each switch node executes the test according to the corresponding test task; 4) determine the availability of each switch node, and obtain network availability comprehensively; the device includes a static topology preprocessing module, an active test task generation module, an active test task execution module and an availability analysis module . The invention can realize the automatic test of the usability of the huge system domain network, and has the advantages of comprehensive test data, accurate test results, fast and high efficiency.

Description

technical field [0001] The invention relates to the technical field of giant system domain network testing, in particular to an automatic testing method and device for availability of giant system domain network. Background technique [0002] A giant system area network usually uses a large number of core switches, aggregation switches, and access switches to form a hierarchical high-speed Ethernet, and then connects computing server clusters and large-capacity storage systems, mainly between computing servers and between computing servers and storage systems. Provide high-speed information transmission support between them. The availability and transmission performance of the giant system area network are important factors affecting the external service capability of the entire network. Problems such as switches, Ethernet interfaces, and fiber links in the network directly affect the transmission performance of the entire or partial area of ​​the giant system area network. ...

Problems solved by technology

However, due to the different support of different network devices for the SNMP protocol and the functional limitations of the SNMP protocol itself, this type of passive test method has great limitations. At the same time, it cannot directly send service traffic to the network, and cannot realize the performance bottleneck point in the network. positioning

The current active measurement method is to obtain performance parameters such as link traffic or end-to-end bandwidth, delay, and packet loss rate by selecting some reference test points and sending measurement probe packets, and analyze the connectivity, reliability, and performance of the network accordingly. Stability, but the selection of reference test points and the generation of measurement tasks need to be based on manual selection. For complex-structured giant system domain networks, it is difficult to locate equipment, interfaces, and link fault points, with poor timeliness and low accuracy.
