It is called on "network impairments instrument" of
Network impairments instrument, also known as WAN emulators, instrument damage WAN, WAN Emulation, Network Impairment Emulator.
- Why bring WAN Wide Area Network qualifier?
Early LAN should be very small and very clean, only long distance WAN high complex application environments have a "delay / jitter packet loss + + + error packets out of order" poor conditions, but also for this early in the product development ( if wrong, please great God treatise !! ).
- I prefer to use "network impairments instrument", "Network Impairment Emulator" to describe such products
Because more and more complex LAN environment, inside and outside the firewall application deployment, data centers and other high-speed links will need to emulate "delay / jitter, packet loss, out of order," the environment in a negative stress test
About market applications
Traditional market
- Traditional rate of 10/100 / 1000Mbps, 10Gbps
- Suitable for large groups: satellite communications, 2 / 3G, DSL, WiFi, so long as the network can, for a variety of applications injury granularity huge difference
- Warlords kill war, many suppliers options: Apposite, PacketStrom, IXIA, IWL, HoloWAN, Calnex ...
Emerging Markets and Applications

These are nonsense
Technical requirements eCPRI Internet injury
- Port rate, the current 25G, 50G future
- Delay accuracy, the better the finer the particle size, the range is 0 ~ 0.5ms Follow
- Can be damaged, the filtering rules for specific message to join
- Analog link down state
- Background data flow injection
- Automated script-friendly secondary development interface
