The key Tool Of Productive IT Professionals
WAN emulation is known as a technique that the properties of an existing, designed and/or non-ideal network are simulated to be able to assess efficiency, forecast the effect of change, or otherwise enhance technologies decision-making.

WAN emulation may be accomplished by introducing a tool on the LAN that alters packet flow in a way that imitates the actual behavior of application traffic in the environment being emulated. This product may be whether general-purpose computer running software to execute the network emulation or even a dedicated emulation device. The device incorporates a variety of network attributes into its emulation model - such as the round-trip time across the network (latency), the quantity of accessible bandwidth, a certain degree of packet loss, replication of packets, reordering packets, and/or the degree of network jitter. Desktop computer PCs might be connected to the emulated environment, to ensure that users can go through the efficiency and behavior of applications in that environment first-hand. Similarly, phones can be attached to the emulated environment so that users can straight evaluate VoIP call quality for their own reasons.

Emulation is different from simulation for the reason that a network emulator appears to be a network; end-systems for example desktops is often attached to the emulator and can become if they're mounted on a network. Network simulators are typically programs which run on just one computer, take an abstract explanation from the network traffic (for example a flow arrival procedure) and yield performance statistics (such as buffer occupancy like a function of time).

A WAN emulation emulates the network which connects end-systems, not the end-systems themselves. Systems which emulate the end-systems are known as traffic generators.
