ABSTRACT:
When testing network management applications, it is desirable to show that they will work with large or very large networks, to determine the upper bounds of the applications capabilities, and improvements which might increase the upper bounds. A method of testing a network application is disclosed mapping a layer-3 addresses of a real subnetwork onto a plurality of mapped layer-3 subnetwork addresses for conversations with applications or devices. Packets are modified to change a destination layer-3 address in a mapped subnetwork, pointing to corresponding real IP address and forwarding the packets. The conversation to which a response from a reallayer-3 address relates is identified. The source layer-3 address and packet contents are changed into the appropriate mapped subnetwork and the packet is forwarded to the application or device. An existing test network of any size may be used as the basis for testing the network management application.
