Liaisons referred by this one Reply LS on 3GPP Work on Explicit Congestion Notification for Lower Layer Protocols
Body
1. Description

The IETF Transport and Services Working Group (TSVWG) [1] has prepared the
following drafts and included previous inputs from the 3rd Generation
Partnership Project (3GPP) on topics relating to Explicit Congestion
Notification (ECN):

• draft-ietf-tsvwg-ecn-encap-guidelines [2]
• draft-ietf-tsvwg-rfc6040update-shim [3]

These drafts have been revised in IETF Review and are now thought ready to be
published. The drafts mention the GPRS Tunnelling Protocol (GTP), which is
under the control of 3GPP, and clarify that GTP is in scope of RFC6040.

The drafts are currently in the RFC-editor queue. 3GPP was involved at the
start of the process; therefore, TSVWG thought it may be useful for 3GPP to be
notified of the conclusion.

2. Upcoming Meetings

IETF 120 20-26 July 2024, Vancouver, Canada
