    IPsec Extensions to Support Robust Header Compression over IPsec

Abstract

   Integrating Robust Header Compression (ROHC) with IPsec (ROHCoIPsec)
   offers the combined benefits of IP security services and efficient
   bandwidth utilization.  However, in order to integrate ROHC with
   IPsec, extensions to the Security Policy Database (SPD) and Security
   Association Database (SAD) are required.  This document describes the
   IPsec extensions required to support ROHCoIPsec.

1.  Introduction

   Using IPsec ([IPSEC]) protection offers various security services for
   IP traffic.  However, these benefits come at the cost of additional
   packet headers, which increase packet overhead.  By compressing the
