Abstract

The invention relates to the test technology for network communication devices and discloses a system for testing the multi-activation detection performance of a stack system accurately and efficiently. The system comprises a tester, the stack system composed of two tested devices and two auxiliary test devices, wherein the two tested devices of the stack system are connected through a virtual exchange link and in physical connection with the two auxiliary test devices respectively; and the two auxiliary test devices are connected with a test port of the tester respectively. In addition, the invention further discloses a method for testing the multi-activation detection performance of the network communication devices correspondingly.

Description

technical field [0001] The invention relates to a testing technology for network communication equipment, in particular to a multi-active detection (Multi-Active Detection detect, MAD for short) performance testing system and a corresponding testing method. Background technique [0002] With the development of Netcom communications, people's requirements for network stability and equipment reliability continue to increase. At present, basic network construction has begun to use network system virtualization technology on a large scale, which is called Virtual Switching Technologies (VST for short) in the present invention. ), which is a technology that virtualizes multiple physical devices into a single virtual device based on an internal distributed switching network. A device that deploys virtual switching technology can also be called a stacking system. A virtual switching link (Virtual Switching Link, VSL for short) is a physical link for transmitting control packets th...
