Abstract

New protocols and algorithms are being developed to meet changing operational requirements in the Internet. Simulation is a vital tool to quickly and inexpensively explore the behavior of these new protocol across the range of topologies, cross-traffic, and interactions that might occur in the Internet. This paper describes ns, a widely used, multi-protocol network simulator designed to address the needs of networking researchers. Ns provides multiple levels of abstraction to permit simulations to span a wide-range of scales, emulation, where real-world packets can enter the simulator. We describe the ns architecture and examine the range of ways simulation and ns are used in networking research.
