a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks
the Peer Distributed Transfer Protocol provides a method of transferring files using peers to aid in distribution of content, similar to BitTorrent. PDTP servers export a dynamically changing directory hierarchy, making it somewhat more like HTTP or FTP.
a general purpose monitoring platform. provides a framework dealing with (among others) packet demultiplexing, timers, threads and communication. This allows programmers to concentrate on the precise functionnalities they want to implement...
component-based, modular and open-architecture simulation environment with strong GUI support and an embeddable simulation kernel. Its primary application area is the simulation of communication networks and because of its generic and flexible architectur
