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.

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.
