Technical Summary

Traditionally the explicit congestion notification can deliver only one 
congestion signal in a round-trip time with TCP. This Informational 
document motivates the case for delivering more accurate congestion 
information for TCP. It discusses high-level requirements for methods 
for delivering more accurate congestion information, but does not 
specify such mechanism. Therefore Informational is considered 
appropriate document type.
