                 Limited Domains and Internet Protocols
                   draft-carpenter-limited-domains-13

Abstract

   There is a noticeable trend towards network behaviours and semantics
   that are specific to a particular set of requirements applied within
   a limited region of the Internet.  Policies, default parameters, the
   options supported, the style of network management and security
   requirements may vary between such limited regions.  This document
   reviews examples of such limited domains (also known as controlled
   environments), notes emerging solutions, and includes a related
   taxonomy.  It then briefly discusses the standardization of protocols
   for limited domains.  Finally, it shows the needs for a precise
   definition of "limited domain membership" and for mechanisms to allow
   nodes to join a domain securely and to find other members, including
   boundary nodes.

   This document is the product of the research of the authors.  It has
   been produced through discussions and consultation within the IETF,
   but is not the product of IETF conensus.

1.  Introduction

   As the Internet continues to grow and diversify, with a realistic
   prospect of tens of billions of nodes being connected directly and
   indirectly, there is a noticeable trend towards network-specific and
   local requirements, behaviours and semantics.  The word "local"
