The Path Computation Element (PCE) Architecture introduces the
concept of policy in the context of path computation. This document
provides additional details on policy within the PCE Architecture and
also provides context for the support of PCE Policy. This document
introduces the use of the Policy Core Information Model (PCIM) as a
framework for supporting path computation policy. This document also
provides representative scenarios for the support of PCE Policy.
Working Group Summary
No controversy reported. The working group chairs were not
completely convinced that there was a need for this document,
but members of the working group were supportive, and it is
certainly true that policy is discussed within the PCE
architecture (RFC 4655) and is very applicable for inter-AS PCE.
To the shepherding AD (Ross), the information discussed in this
document is very much central to the point of PCE, and the only
issue is whether it is so obvious that it is not necessary to
actually write it down (but in general it seems better to write
down non-controversial explanatory material).
As reported in the PROTO writeup, there were no problems with
consensus for this document, and when the I-D was accepted by
the WG there was strong support.
This is an informational document that does not specify any
protocol that could be implemented. The work that is ongoing
in the PCE WG is compatible with this document.
Adrian Farrel is the document shepherd. He has personally
reviewed the I-D and believes it is ready for forwarding to
the IESG for publication. Ross Callon is the responsible AD.
There are no IANA actions required. A null IANA section is present.
