The IESG has approved the following document: - 'Conveying Vendor-Specific Constraints in the Path Computation Element communication Protocol' (draft-ietf-pce-rfc7150bis-01.txt) as Proposed Standard This document is the product of the Path Computation Element Working Group. The IESG contact persons are Alia Atlas and Adrian Farrel. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-pce-rfc7150bis/ 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. Personnel Who is the Document Shepherd?
