  IP Security (IPsec) and Internet Key Exchange (IKE) Document Roadmap

Abstract

   Over the past few years, the number of RFCs that define and use IPsec
   and Internet Key Exchange (IKE) has greatly proliferated.  This is
   complicated by the fact that these RFCs originate from numerous IETF
   working groups: the original IPsec WG, its various spin-offs, and
   other WGs that use IPsec and/or IKE to protect their protocols'
   traffic.

   This document is a snapshot of IPsec- and IKE-related RFCs.  It
   includes a brief description of each RFC, along with background
   information explaining the motivation and context of IPsec's
   outgrowths and extensions.  It obsoletes RFC 2411, the previous "IP
   Security Document Roadmap."

   The obsoleted IPsec roadmap (RFC 2411) briefly described the
   interrelationship of the various classes of base IPsec documents.
   The major focus of RFC 2411 was to specify the recommended contents
   of documents specifying additional encryption and authentication
   algorithms.
