Abstract
The Path Computation Element (PCE) architecture is set out in RFC4655. The architecture is extended for multi-layer networking withthe introduction of the Virtual Network Topology Manager (VNTM) inRFC 5623 and generalized to Hierarchical PCE (H-PCE) in RFC 6805.
These three architectural views of PCE deliberately leave some keyquestions unanswered, especially with respect to the interactionsbetween architectural components. This document draws out thosequestions and discusses them in an architectural context withreference to other architectural components, existing protocols, andrecent IETF efforts.
This document does not update the architecture documents and does notdefine how protocols or components must be used. It does, however,suggest how the architectural components might be combined to provideadvanced PCE function.
