network emulation
Network emulation is a technique where the properties of an existing, planned and/or non-ideal network are simulated using emulation of specific routers and other network equipment, as opposed network simulation where simplified mathematical models of data sources, channels and protocols are applied. The aim is educational, to develop skills in configuring network equipment, or scientific, to in order to assess performance, predict the impact of change, or otherwise optimize technology decision-making.
==Methods of emulation==
Network emulation is the act of introducing a device to a test network (typically in a lab environment) that alters packet flow in such a way as to mimic the behavior of a production, or live, network — such as a LAN or WAN. This device may be either a general-purpose computer running software to perform the network emulation or a dedicated emulation device. Devices 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. Higher-end network emulators can also mimic typical Layer 1 physical errors such as Bit Error Rate, Loss of Signal, Output Bit Rotation, and others.
It is commonly known that networks are imperfect — private or public. They introduce delay and errors. They go down. They drop packets. The primary goal of network emulation is to create an environment whereby users can connect up their devices, applications, products and/or services and evaluate their performance, stability, or functionality against real-world network scenarios. Once tested in a controlled environment against actual network conditions, users can have confidence that the item being tested will perform as expected.
