Integration of Robust Header Compression over
IPsec Security Associations
Abstract
IP Security (IPsec) provides various security services for IP
traffic. However, the benefits of IPsec come at the cost of
increased overhead. This document outlines a framework for
integrating Robust Header Compression (ROHC) over IPsec (ROHCoIPsec).
By compressing the inner headers of IP packets, ROHCoIPsec proposes
to reduce the amount of overhead associated with the transmission of
traffic over IPsec Security Associations (SAs).
