1. Summary

Document shepherd is Pasi Sarolahti. Responsible AD is Martin Stiemerling.

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.
