                 Inclusion of Manageability Sections in
          Path Computation Element (PCE) Working Group Drafts


   It has often been the case that manageability considerations have
   been retrofitted to protocols after they have been specified,
   standardized, implemented, or deployed.  This is sub-optimal.
   Similarly, new protocols or protocol extensions are frequently
   designed without due consideration of manageability requirements.

   The Operations Area has developed "Guidelines for Considering
   Operations and Management of New Protocols and Protocol Extensions"
   (RFC 5706), and those guidelines have been adopted by the Path
   Computation Element (PCE) Working Group.

   Previously, the PCE Working Group used the recommendations contained
   in this document to guide authors of Internet-Drafts on the contents
   of "Manageability Considerations" sections in their work.  This
   document is retained for historic reference.

1.  Introduction

   This document is produced for historic reference.

   When new protocols or protocol extensions are developed, it is often
   the case that not enough consideration is given to the manageability
   of the protocols or to the way in which they will be operated in the
   network.  The result is that manageability considerations are only
   understood once the protocols have been implemented and sometimes not
   until after they have been deployed.

   The resultant attempts to retrofit manageability mechanisms are not
   always easy or architecturally pleasant.  Furthermore, it is possible
   that certain protocol designs make manageability particularly hard to

   Recognizing that manageability is fundamental to the utility and
   success of protocols designed within the IETF, and that simply
   defining a MIB module does not necessarily provide adequate
   manageability, this document was developed to define recommendations
   for the inclusion of Manageability Considerations sections in all
   Internet-Drafts produced within the PCE Working Group.  It was the
   intention that meeting these recommendations would ensure that proper
   consideration was given to the support of manageability at all stages
   of the protocol development process from Requirements and
   Architecture through Specification and Applicability.

   It is clear that the presence of such a section in an Internet-Draft
   does not guarantee that the protocol will be well-designed or
   manageable.  However, the inclusion of this section will ensure that
   the authors have the opportunity to consider the issues, and, by
   reading the material in this document, they will gain some guidance.
