IGen

Slogan: 
IGen is a network topology generator.

IGen is a network topology generator. Unlike GT-ITM and BRITE, IGen does not rely on probabilistic methods to generate network topologies. Since real networks are the outcome of a careful network design, IGen implements various network design heuristics such as MENTOR, MENTour, Delaunay triangulation and Two Trees for the purpose of building network topologies.

A recent fork of this code is available at http://genc.tato.al/2017/10/17/igen-topology-generator-revived/

Network Topology Generation

Sun, 07/15/2007 - 17:57 by Bruno Quoitin • Categories:

Building increasingly precise and realistic network topologies is an important issue for the purpose of evaluating networking applications. Still, the generation of router-level topologies has not been widely covered. Though, the properties of the router-level topologies have a significant impact on simulation results. For instance, the evaluation of applications such as Voice/Video over IP, P2P, routing protocols and traffic engineering methods critically depends on the properties captured by the topology model.

Measuring the Internet

Mon, 07/02/2007 - 11:44 by Olivier Bonaventure • Categories:

The Internet is a very large scale complex system whose properties are not entirely completely known. However, a detailed knowledge of the Internet is key to understand the mechanisms and protocols that work well and those that could be improved.

LinShim6

Slogan: 
A Linux implementation for Shim6.

Shim6 is a mechanism that allows multihomed hosts to take profit from the multiple paths available across the Internet. It is designed as a new intermediate sublayer inside the IPv6 network layer. Shim6 is still a work in progress. The set of drafts produced by the IETF Shim6 working group is available here.
