Description
Summary:Computer networks provide the underlying support for the information explosion that has revolutionized not only academia, but industry, government, the fourth estate and even military combat operations. Networks composed of hundreds of stations on several subnets are extremely complex. This complexity makes it very difficult to evaluate the operational performance of a local network. It is even more challenging to contemplate the end results of modifying or reconfiguring existing networks. The inherent complexity of non-trivial networks makes systematic simulation study difficult. Hours of wall clock time may be required to simulate a few seconds of network operations. New simulation techniques are needed in order to realize the full potential of simulation in analyzing computer networks. This research demonstrates a strategy based on mixing levels of resolution within a multilevel abstraction hierarchy. Such a strategy allows a researcher to focus on packet by packet detail in one part of the simulation while other parts of the simulation are running at a functionally equivalent higher level of abstraction. The implementation of a multilevel, mixed-resolution network simulation is done in OPNET, a communications-oriented simulation language and environment. The construction of a high-fidelity network simulation that can be observed at different levels of abstraction demonstrates that mixed-resolution simulation is both flexible and extensible. Multilevel, mixed-resolution simulation is an important enabling technology to support emerging research on the detailed behavior of TCP/IP networks.
