Sorry for the cross posting but I thought input from all these groups might be beneficial. I'm looking for some type of simulation program that would enable a network manager to view the route taken by packets in a complex IP network that utilizes more than just hop-count metrics. Imagine a 100+ node network with link metrics ranging from 1 to 2000. The goal is to determine (quickly and easily) the path taken by a packet from any particular source point to any particular destination point without having to manually add up all of the metric combinations to determine the least cost path. Another goal is to be able to create a link failure and observe the new least cost path. Another goal is to be allow what-if scenarios where the network manager can change the metric on a given link(s) and see the result. Input to the simulation could be as simple as a flat file of point-to-point links and their associated metrics. Output could also be a character-based flat file. Graphical I/O would be ideal. Note: I'm not particularly interested in simulating traffic patterns with varying inter-arrival rates so something like Bones or CACI Network-II might be overkill. Besides, I don't even know if they can provide what I'm looking for above (can they?). On the other hand, viewing traffic patterns might come in handy later. Hmmmmm. Any suggestions?
