A new Request for Comments is now available in online RFC libraries. RFC 9347 Title: Aggregation and Fragmentation Mode for Encapsulating Security Payload (ESP) and Its Use for IP Traffic Flow Security (IP-TFS) Author: C. Hopps Status: Standards Track Stream: IETF Date: January 2023 Mailbox: chopps@chopps.org Pages: 31 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ipsecme-iptfs-19.txt URL: https://www.rfc-editor.org/info/rfc9347 DOI: 10.17487/RFC9347 This document describes a mechanism for aggregation and fragmentation of IP packets when they are being encapsulated in Encapsulating Security Payload (ESP). This new payload type can be used for various purposes, such as decreasing encapsulation overhead for small IP packets; however, the focus in this document is to enhance IP Traffic Flow Security (IP-TFS) by adding Traffic Flow Confidentiality (TFC) to encrypted IP-encapsulated traffic. TFC is provided by obscuring the size and frequency of IP traffic using a fixed-size, constant-send-rate IPsec tunnel. The solution allows for congestion control, as well as nonconstant send-rate usage. This document is a product of the IP Security Maintenance and Extensions Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
