Abstract

   This document investigates the benefits of cross-area work in the
   IETF.  It is examines existing cross-area work and identifies other
   possibilities for work that spans more than one area.  The intention
   is to help community members who focus their work within a specific
   area to understand related work in other areas and to motivate
   efficient cooperation across different areas in the IETF.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

1.  Introduction

   With the development of new network technologies such as cloud
   computing, 5G, IoT, etc., very many applications are carried over the
   network.  Each has different needs for network bandwidth, latency,
   jitter, and packet loss, etc.

   Work in the IETF is divided into Areas.  The demands of the new
   technologies motivates innovation and new architectures in multiple
   network layers, and resulting cross-area work is increasing in the
   IETF.  Existing protocol practice shows that people who focus on one
   specific area are sometimes not aware of related work in different
   areas.  Some cross-area work is not recognized until late in the
   lifecycle so that useful experiences cannot be shared early in the
   development.  Fixing problems that are identified late can become
   time consuming.

   This document investigates the benefits of cross-area work in the
   IETF.  It is examines existing cross-area work and identifies other
   possibilities for work that spans more than one area.  The intention
