AdventNet Simulation Toolkit comprises agent simulator and network simulator for testing, training and demonstration of network management applications. The network simulator enables simulation of SNMP (v1, v2c, v3), TL1, TFTP, FTP Telnet and IOS devices, on a single PC. It enables recording of real networks and traps, allows advanced modeling of agent/network behavior, PDU scrambler,management through RMI and dynamic virtual IP configuration.
