In-network research, network simulation may be a technique whereby a software program models the behavior of a network by calculating the interaction between the various network entities (routers, switches, nodes, access points, links, etc.). Most simulators use discrete event simulation – the modeling of systems during which state variables change at discrete points in time. The behavior of the network and therefore the various applications and services it supports can then be observed during a test lab; various attributes of the environment also can be modified during a controlled manner to assess how the network/protocols would behave under different conditions.
Computer Network Simulation within the sense connection of two or more computing systems linked together for communication. Networking is the practice of interfacing two or more computing devices with one another for the aim of sharing data. Computer networks are built with a mixture of hardware and software.
