Basic Host Identity Protocol (HIP) Extensions for
Traversal of Network Address Translators
Abstract
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 a 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
networking applications.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for examination, experimental implementation, and
evaluation.
This document defines an Experimental Protocol for the Internet
community. This document is a product of the Internet Engineering
Task Force (IETF). It represents the consensus of the IETF
community. It has received public review and has been approved for
publication by the Internet Engineering Steering Group (IESG). Not
all documents approved by the IESG are a candidate for any level of
Internet Standard; see Section 2 of RFC 5741.
