Please send substantive comments to the ietf@ietf.org mailing lists by 2012-08-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Computing optimum routes for Label Switched Paths (LSPs) across multiple domains in MPLS Traffic Engineering (MPLS-TE) and GMPLS networks presents a problem because no single point of path computation is aware of all of the links and resources in each domain. A solution may be achieved using the Path Computation Element (PCE) architecture. Where the sequence of domains is known a priori, various techniques can be employed to derive an optimum path. If the domains are simply-connected, or if the preferred points of interconnection are also known, the Per-Domain Path Computation technique can be used. Where there are multiple connections between domains and there is no preference for the choice of points of interconnection, the Backward Recursive Path Computation Procedure (BRPC) can be used to derive an optimal path. This document examines techniques to establish the optimum path when the sequence of domains is not known in advance. The document shows how the PCE architecture can be extended to allow the optimum sequence of domains to be selected, and the optimum end-to-end path to be derived through the use of a hierarchical relationship between domains.

This draft is a work item of the Path Computation Element Working Group of= the IETF. Title : Conveying Vendor-Specific Constraints in the Path Comput= ation Element Protocol Author(s) : Fatai Zhang Adrian Farrel Greg Bernstein Filename : draft-ietf-pce-vendor-constraints-07.txt Pages : 10 Date : 2012-08-26 Abstract: 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. The mechanisms defined for indicating objective functions include the capability to convey vendor-specific objective functions. This document defines a facility to carry vendor-specific constraints in PCEP.

Title : The Application of the Path Computation Element Architec= ture to the Determination of a Sequence of Domains in MPLS and GMPLS Author(s) : Daniel King Adrian Farrel Filename : draft-ietf-pce-hierarchy-fwk-05.txt Pages : 31 Date : 2012-08-28 Abstract: Computing optimum routes for Label Switched Paths (LSPs) across multiple domains in MPLS Traffic Engineering (MPLS-TE) and GMPLS networks presents a problem because no single point of path computation is aware of all of the links and resources in each domain. A solution may be achieved using the Path Computation Element (PCE) architecture. Where the sequence of domains is known a priori, various techniques can be employed to derive an optimum path. If the domains are simply-connected, or if the preferred points of interconnection are also known, the Per-Domain Path Computation technique can be used. Where there are multiple connections between domains and there is no preference for the choice of points of interconnection, the Backward Recursive Path Computation Procedure (BRPC) can be used to derive an optimal path. This document examines techniques to establish the optimum path when the sequence of domains is not known in advance. The document shows how the PCE architecture can be extended to allow the optimum sequence of domains to be selected, and the optimum end-to-end path to be derived through the use of a hierarchical relationship between domains.

This draft is a work item of the Path Computation Element Working Group of= the IETF. Title : Conveying Vendor-Specific Constraints in the Path Comput= ation Element Protocol Author(s) : Fatai Zhang Adrian Farrel Greg Bernstein Filename : draft-ietf-pce-vendor-constraints-08.txt Pages : 10 Date : 2012-08-30 Abstract: 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. The mechanisms defined for indicating objective functions include the capability to convey vendor-specific objective functions. This document defines a facility to carry vendor-specific constraints in PCEP.
