1. Description The IETF Operations and Management Area Working Group (OPSAWG) [1] would like to kindly inform the 3GPP TSG SA WG5 and 3GPP TSG CT WG4 that OPSAWG is currently working on the following Internet-Draft: “Export of GTP-U Information in IP Flow Information Export (IPFIX)” [2]. This document specifies IPFIX Information Elements (IEs) that can be used to export information contained in the GTP-U header such as Tunnel Endpoint Identifier (TEID), QoS Flow Identifier (QFI), and PDU Type from the PDU Session Container extension header. IETF OPSAWG aims to publish this Internet-Draft as a proposed standard RFC in the upcoming months. IETF OPSAWG kindly asks 3GPP TSG SA WG5 and 3GPP TSG CT WG4 to review this document and provide comments, if any. Note that the OPSAWG encourages the use of working group mailing list [3] as the most effective and expedient way of exchanging information, answering questions, and clarifying concerns. 2. Upcoming Meetings IETF 122, 15 - 21 March 2025, Bangkok, TH IETF 123, 19 - 25 July 2025, Madrid, ES 3.
