GT-ITM Tool

I want to download the set of tools of Georgia Tech Internet Topology Model (GT-ITM) for the conversion of network topologies so can you please provide me the process to download it? Also tell me the uses of these tools?

Hii sir, I Wants to get the Information About the Modeling Topology of Large Internetworks Approach Given by the College of Computing Georgia Institute of Technology ?

Modeling Topology of Large Internetworks

The explosive growth of internetworking, and particularly of the Internet, has been accompanied by a wide range of internetworking problems related to routing, resource reservation, and administration.

The study of algorithms and policies to address such problems often involves simulation or analysis using an abstraction or model of the actual network structure and applications.

The reason is clear: networks that are large enough to be interesting are also expensive and difficult to control; therefore they are rarely available for experimental purposes. Moreover, it is generally more efficient to assess solutions using analysis or simulation --- provided the model is a "good" abstraction of the real network and application.

It is therefore rather remarkable that studies based on randomly-generated or trivial network models are so common, while rigorous analyses of how the results scale or how they can be applied to actual networks are extremely rare.

Hello sir, what is GT-ITM Tool? Is there any one can provide me basic info about GT-ITM Tool?

The GT-ITM Tool is a collection of routines to generate and analyze graphs using a wide variety of models for internetwork topology.

The graphs are generated in Don Knuth's SGB format; a routine is provided to convert to an alternative format that may be easier to parse.

The GT-ITM Topologies is a complete set of tools for the conversion of network topologies following the Georgia Tech Internet Topology Model (GT-ITM) to the InetUnderlay model used by OverSim.

The provided tar ball includes the GT-ITM topology generator, the BRITE topology tool patched with NED language support and the necessary updates to the ctopology.cc/h files of OMNeT++ for the support of weighted shortest paths.
