WS1008 network damage tester has high-performance network damage simulation function, redundant link test function and line speed flow generation function, and provides a comprehensive network system test program, which can fully test and verify the network system's anti-damage ability, link switching ability and data forwarding ability.It provides effective test support for high reliability network system.
The network damage simulation function has a variety of damage simulation capabilities such as delay, disorder, packet loss, packet insertion, repeated message, modified message, background traffic, etc. Through flexible damage parameter configuration, various kinds of data damage in the real wan environment can be created.
The test function of redundant link provides the link high-speed on-off ability and accurate switching time measurement ability, and has the function of automatic alternation of main and standby links, which can allow users to easily verify the switching performance of main and standby links, and provide sufficient basis for verifying and improving the redundant network system.
 The traffic generation function provides 10/100/1000m port line speed traffic generation capability, which can be used for pressure testing of various network devices to fully verify the data forwarding capability of the tested devices.

Impairment Emulator 
Provide 8 port 4 link bidirectional simulation function It has rich damage functions and can accurately realize damage simulation under linear velocity flow
The jitter delay can be realized by the delay forwarding of all messages or specific messages
All packets or specific packets are discarded, repeated, out of order and modified according to the set proportion Messages of specific content can be inserted according to the set rate, supporting the construction and insertion of extra-long frames, ultra-short frames and FCS wrong frames Background data traffic that can be inserted at a specified rate
Redundant Link Testing
In the network system, the on - off of Ethernet link can be controlled by software in real time, and the physical fault of communication link can be simulated For redundant network systems with primary and secondary links, the switching time of primary and secondary links can be accurately measured With the function of automatic alternation of main and backup links, the automatic cycle on and off test of multiple main and backup links can be realized It can be connected in the network system for a long time in series. By default, the data can be transmitted directly without affecting the normal operation of the original system It is widely used in test system, debugging system and test system carried by Ethernet
Standard Traffic Generator 
Provide 24 × 10/100/1000m RJ45 port, which can generate line speed flow Adjustable speed based on port Source MAC address, destination MAC address, frame length and net load can be set Traffic statistics can be based on ports Statistical items include number of received messages, number of sent messages, receiving rate, sending rate, FCS error packet
