Problems solved by technology

However, the market price of professional network testers such as Spirent or Ixia is more than 200,000 US dollars, and the cost is high
In addition, using a professional network tester such as Spirent or Ixia to simulate the damage of a 40G link is technically realized through a dedicated network chip, which is relatively complicated and not very versatile.

Abstract

The invention provides a method for performing perturbation simulation on link between Leaf-Spine switches in a network. The method comprises the following steps: disconnecting a link between a Leaf switch and a Spine switch; coupling the Spine switch with a first network card, and coupling the Leaf switch with a second network card; and communicating the first network card with the second networkcard through a server, so that traffics entering from the first network card are entirely forwarded to the second network card through the server, and the traffics entering from the second network card are entirely forwarded to the first network card through the server, wherein abnormal perturbation is generated in the server through first software simulation. The invention further provides a device for performing perturbation simulation on link between Leaf-Spine switches in the network.

Description

technical field [0001] The invention relates to cloud network monitoring technology, in particular to a method and device for performing disturbance simulation on links between Leaf-Spine switches. Background technique [0002] Due to the transformation of network technology, the new network innovation architecture represented by Software Defined Network (SDN) provides a way to realize network virtualization - by separating the control plane of network equipment from the data plane, network traffic is realized. The flexible control of the network makes the network more intelligent as a pipeline. [0003] In order to test the abnormal disturbance of the high-speed communication link between the Leaf-Spine switches in the SDN Fabric network, the existing solutions generally use professional network testers such as Spirent or Ixia (such as Attero-100G / 40G model network damage tester) to simulate abnormal disturbances of network links (such as 40G network links). However, the...
