This document specifies extensions to the Host Identity Protocol
(HIP) to facilitate Network Address Translator (NAT) traversal. The
extensions are based on the use of the Interactive Connectivity
Establishment (ICE) methodology to discover a working path between
two end-hosts, and on standard techniques for encapsulating
Encapsulating Security Payload (ESP) packets within the User Datagram
Protocol (UDP). This document also defines elements of procedure for
NAT traversal, including the optional use of a HIP relay server.
With these extensions HIP is able to work in environments that have
NATs and provides a generic NAT traversal solution to higher-layer
Working Group Summary
There was nothing in the Working Group review process worth noting.
There are at least two independent implementations of this document.
These implementations have been tested against each other and are
interoperable. The WG did not want to request the publication of this
document before having independent interoperable implementations. That
is why we did not requested the publication of this draft before.
