The Harvard TCP/IP network simulator, based on a simulation methodology proposed by S.Y. Wang and H.T. Kung at INFOCOM'99, uses existing real-world BSD code (including the TCP/IP stack, application programs, utilities and tools, etc.) to provide high-fidelity and extensible TCP/IP network simulation. This version (version 1.0) is being used by more than 150 universities, industrial research labs, and ISPs. Questions, suggestions, and source code contributions should be sent to shieyuan@eecs.harvard.edu.

New and More Advanced Software (the successor to the Harvard network simulator)

NCTUns network simulator and emulator (the web site )

NCTUns is a high-fidelity and extensible network simulator and emulator capable of simulating various protocols used in both wired and wireless networks. Its core technology is based on the novel kernel re-entering methodology invented by Prof. S.Y. Wang [1, 2] when he was pursuing his Ph.D. degree at Harvard University. Due to this novel methodology, NCTUns provides many unique advantages that cannot be easily achieved by traditional network simulators such as ns-2 [3] and OPNET [4].

After obtaining his Ph.D. degree from Harvard University in September 1999, Prof. S.Y. Wang returned to Taiwan and became a professor in the Department of Computer Science, National Chiao Tung University (NCTU), Taiwan, where he founded his "Network and System Laboratory." Since that time, Prof. S.Y. Wang has been leading and working with his students to design and implement NCTUns (the NCTU Network Simulator) for many years.

The NCTUns network simulator and emulator has many useful features listed below:

At NCTU, Prof. S.Y. Wang and his students are working hard to continuously add more functionalities and features to NCTUns. They want to make it a high-quality software and would like to contribute it to the communication and networking community.
