Classical network models include :

BRITE : http://www.cs.bu.edu/brite/
GT-ITM : http://www.cc.gatech.edu/projects/gtitm/

An alternative is to start from network maps such as those gathered by
the rocketfuel project

The second issue is the traffic matrix. I haven't seen any model of
traffic matrix and the only publically available information about
traffic matrixes is the Abilene website :

The papers that I have seen usually start with proprietary traffic
matrix information and perform some scaling or permutations on this
