IKEv2 Extensions to Support Robust Header Compression over IPsec
Abstract
In order to integrate Robust Header Compression (ROHC) with IPsec, a
mechanism is needed to signal ROHC channel parameters between
endpoints. Internet Key Exchange (IKE) is a mechanism that can be
leveraged to exchange these parameters. This document specifies
extensions to IKEv2 that will allow ROHC and its associated channel
parameters to be signaled for IPsec Security Associations (SAs).

RFC 5857 IKEv2 Extensions to Support ROHCoIPsec May 2010
1. Introduction
Increased packet header overhead due to IPsec [IPSEC] can result in
the inefficient utilization of bandwidth. Coupling ROHC [ROHC] with
IPsec offers an efficient way to transfer protected IP traffic.
ROHCoIPsec [ROHCOIPSEC] requires configuration parameters to be
initialized at the compressor and decompressor. Current
specifications for hop-by-hop ROHC negotiate these parameters through
a link-layer protocol such as the Point-to-Point Protocol (PPP)
(i.e., ROHC over PPP [ROHC-PPP]). Since key exchange protocols
