Cross-Area Work in the IETF
draft-li-cross-area-ietf-work-00
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].
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-

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
