Abstract
This document describes an approach for providing RSVP protocol
services over IP tunnels. We briefly describe the problem, the
characteristics of possible solutions, and the design goals of our
approach. We then present the details of an implementation which
meets our design goals.
1. Introduction
IP-in-IP "tunnels" have become a widespread mechanism to transport
datagrams in the Internet. Typically, a tunnel is used to route
packets through portions of the network which do not directly
implement the desired service (e.g. IPv6), or to augment and modify
the behavior of the deployed routing architecture (e.g. multicast
routing, mobile IP, Virtual Private Net).
Many IP-in-IP tunneling protocols exist today. [IP4INIP4] details a
method of tunneling using an additional IPv4 header. [MINENC]
describes a way to reduce the size of the "inner" IP header used in
[IP4INIP4] when the original datagram is not fragmented. The generic
tunneling method in [IPV6GEN] can be used to tunnel either IPv4 or
IPv6 packets within IPv6. [RFC 1933] describes how to tunnel IPv6
