- Network Emulator
Network emulation introduces a physical (or virtual) device to a test network (typically in a lab environment) that alters packet flow in such a way as to mimic the behaviour of a production, or live, network such as a LAN, WAN, Tactical Radio or SATCOM. This device may be either a general-purpose computer running software to perform the network emulation or a dedicated emulation device which usually does link emulation. Network emulators incorporate a varying amount of standard network attributes into their designs including the round-trip time across the network (latency), the amount of available bandwidth, a given degree of packet loss, duplication of packets, reordering packets, corruption and modification of packets, and/or the severity of network jitter. Those emulators may be used in situations where real network links cannot be used, e.g. during Collective Training Exercises (CTE).
