Title : Unanswered Questions in the Path Computation Element Architecture
Authors : Adrian Farrel
Daniel King
Filename : draft-ietf-pce-questions-06.txt
Pages : 26
Date : 2014-06-03
Abstract:
The Path Computation Element (PCE) architecture is set out in RFC
4655. The architecture is extended for multi-layer networking with
the introduction of the Virtual Network Topology Manager (VNTM) in
RFC 5623, and generalized to Hierarchical PCE (H-PCE) in RFC 6805.
These three architectural views of PCE deliberately leave some key
questions unanswered especially with respect to the interactions
between architectural components. This document draws out those
questions and discusses them in an architectural context with
reference to other architectural components, existing protocols, and
recent IETF work efforts.
This document does not update the architecture documents and does not
define how protocols or components must be used. It does, however,
suggest how the architectural components might be combined to provide
advanced PCE function.
