Technical Summary
The Path Computation Element Protocol (PCEP) is used to convey path
computation requests and responses between Path Computation Clients
(PCCs) and Path Computation Elements (PCEs), and also 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-Variable that
can be carried in any existing PCEP object.
Working Group Summary
No strong controversy on the document, but the comment about
the actual need of defining proprietary fields within a standard
protocol came up several times.
Document Quality
Some implementations claim to use the extensions defined in the I-D.
Personnel
Julien Meuric is the Document Shepherd.
Stewart Bryant is the Responsible Area Director.
RFC Editor Note
Section 1
New text at the end of the section
NEW
It should be noted that by the very definition of "vendor-specific",
the inclusion of either a Vendor Information object or the VENDOR-
INFORMATION-TLV implies an inability to interoperate at a functional
level with implementations from other vendors unless there is some
cooperation agreement between vendors. Sections 2.1 and 3.1 discuss
backward compatibility which indicates how these protocol constructs
are handled by implementations that either do not support them at
all, while text in Sections 2 and 3 describes how implementations
handle the constructs if they understand them, but do not support the
embedded Enterprise Number that indicates to which vendor the
constructs apply.
When vendor-specific information is used by an implementation, the
vendor is encouraged to document the meaning of the information to
encourage wider use and implementation. In particular, when there is
more general interest in a vendor-specific extension, the vendor is
encouraged to bring it to the IETF for standardisation as a regular
protocol construct moving it out of the vendor-specific space.
