Sally and the IRTF's TMRG have been active on this front. See http://tools.ietf.org/html/rfc5033 
  for "Specifying New Congestion Control Algorithms" and especially http://tools.ietf.org/html/draft-irtf-tmrg-metrics-11 
  for "Metrics for the Evaluation of Congestion Control Mechanisms".

There's a related effort underway to define a suite of standardized  
test scenarios for the initial evaluation of new congestion control  
methods; a preliminary writeup is at http://people.nokia.net/~lars/papers/2008-pfldnet.pdf 
. Some of the people involved in this effort are planning to make an  
"implementation| of the test suite available for ns2.
