Abstract: According to an embodiment of the present invention, a router is converted into a bulk call generator which generates packets with Internet protocol (IP) addresses for the purpose of simulating network traffic. These packets are initially either captured or created. When the packets are captured, they are captured from actual network traffic and rerouted to various selected IP addresses which are used for simulation purposes. Alternatively, when the packets are created, they are created within the converted router and various selected IP addresses, reserved for simulation purposes, are assigned to the packets. The various selected IP addresses may be in a range which is user configurable. The IP addresses may be selected from this range by any method, such as incrementation, decrementation, or random selection. Connections are set up according to a routing table based on the IP addresses of the various data packets.
