Abstract

   This document suggests general architectural and policy questions
   that the IETF community has to address when working on new standards
   and protocols.  We note that this document contains questions to be
   addressed, as opposed to guidelines or architectural principles to be
   followed.

1.  Introduction

   This document suggests general architectural and policy questions to
   be addressed in our work in the IETF.  This document contains
   questions to be addressed, as opposed to guidelines or architectural
   principles to be followed.  These questions are somewhat similar to
   the "Security Considerations" currently required in IETF documents
   [RFC 2316].

   This document is motivated in part by concerns about a growing lack
   of coherence in the overall Internet architecture.  We have moved
   from a world of a single, coherent architecture designed by a small
   group of people, to a world of complex, intricate architecture to
   address a wide-spread and heterogeneous environment.  Because
   individual pieces of the architecture are often designed by
   sub-communities, with each sub-community having its own set of
   interests, it is necessary to pay increasing attention to how each
   piece fits into the larger picture, and to consider how each piece is
   chosen.  For example, it is unavoidable that each of us is inclined
   to solve a problem at the layer of the protocol stack and using the
   tools that we understand the best;  that does not necessarily mean
   that this is the most appropriate layer or set of tools for solving
   this problem in the long-term.
