An SNMP simulator is a type of computer simulation, that simulates the Simple Network Management Protocol (SNMP) agent. Contrary to network simulation, which models the behavior of a network within a computer, the SNMP simulator actually interfaces with outside systems, for example Network Management Application software. An SNMP Simulator fools the Network Management Application software into believing it is talking via the SNMP protocol to one or more devices, just like a flight simulator allows a pilot to believe they are flying a plane.
