Technical Summary
The Path Computation Element communication Protocol (PCEP) is used to
convey path computation requests and responses both between Path
Computation Clients (PCCs) and Path Computation Elements (PCEs) and
between cooperating PCEs. In PCEP, the path computation requests
carry details of the constraints and objective functions that the PCC
wishes the PCE to apply in its computation.
This document defines a facility to carry vendor-specific information
in PCEP using a dedicated object and a new Type-Length-Value (TLV)
that can be carried in any PCEP object that supports TLVs.
This document obsoletes RFC 7150. The only changes from that
document are a clarification of the use of the new Type-Length-Value
and the allocation of a different code point for the VENDOR-
INFORMATION object.
Working Group Summary
This bis versions became necessary because of an inadvertant
clash with codepoints used in another Internet-Draft that had been
deployed without IANA allocation. The PCE working group has
conducted a survey of implementations and deployments of RFC 7150
and considers that this change is safe and does not harm early
implementers of RFC 7150.
Document Quality
Some implementations claim to use the extensions defined in the I-D. The original RFC 7150 already passed IESG review.
