Thanks a lot. Now, any ideas from the veterans on creating a simulation
environment for the performance analysis of such schemes. Initially we
thought about creating a "completely random" network, i.e., a network which
has a given number of nodes and given number of links but the connections
between those nodes are completely random. The traffic sources and
destinations are also random and so are the link metrics. It didn't sound
like a good idea.
Any work or suggestions in creating a network where such simulations can be
run. Purpose of simulations would be evaluating performance of traffic
engineering algorithms based on IGP metrics. The performance would be in
terms of recovery time in cases of failures. Are there any papers which
suggest using some network and traffic models for running IGP simulations?
Thanks again,
Zartash

According to citesee, the INFOCOM2000 paper that proposed to set to IGP
metric for traffic engineering purposes is cited by 40 papers.
See http://citeseer.nj.nec.com/context/1075088/261661
The paper below is a survey paper that appeared recently and most
citations refer to the INFOCOM or the JSAC paper
