TRansparent Interconnection of Lots of Links : Explicit Congestion Notification Support

Overview

RFC 9600, “TRansparent Interconnection of Lots of Links : Explicit Congestion Notification Support”, is a Proposed Standard document published in August 2024 by D. Eastlake 3rd, B. Briscoe. The canonical text is published by the RFC Editor.

Abstract

Explicit Congestion Notification (ECN) allows a forwarding element to notify downstream devices, including the destination, of the onset of congestion without having to drop packets. This can improve network efficiency through better congestion control without packet drops. This document extends ECN to TRansparent Interconnection of Lots of Links (TRILL) switches, including integration with IP ECN, and provides for ECN marking in the TRILL header extension flags word (RFC 7179).
