Abstract
Abstract A method and system for testing real-time delivery of packets of data in an application utilized in a computer network includes a first host computer, a second host computer, and a simulator all configured on a local area network segment of a second computer network. A first address is assigned to the first host computer and a second address is assigned to the second host computer. The simulator is configured as a router through which the first and second host computers communicate with each other. Any combination of possible network conditions associated with the computer network are entered into the simulator. The packets of data are formed and transmitted from one of the first and second host computers to the simulator and processed according to the entered network conditions to obtain simulation data.
