As a follow-up, AT&T's work on estimating traffic matrixes from link 
loads can be found at
Note that there is a paper on traffic engineering using these estimates.
	"Traffic Engineering with Estimated Traffic Matrices",
	   ACM SIGCOMM Internet Measurement Conference 2003.

I know Sprint have some similar estimation work -- see the URL below.
