Simnet

Welcome to the Simnet Network Simulator Home Page

Simnet is a discrete-event network simulator, designed specifically for analyzing network-security protocols. The simulator was created for JHU's network security course (CS 424) so its design and implementation is focused on simplicity of abstraction and extensibility. Moreover, its modular architecture allows operators to dynamically customize running simulations. Simnet is not only scalable and efficient, but provides a viable platform for prototyping and analyzing non-trivial security protocols.

Project

The flexibility and extensibility of Simnet has provided the necessary resources for many educational and research-oriented projects, some of which include:

Pushback
Worm Modeling
PK-DNSSEC
SynKill
VPN

Kerberos
SSL/TLS
Scalable VPN Provisioning
Various versions of Traceback
Hop Count Filtering
