Body |
The PCE Working Group of the IETF is pleased to inform you of the publication of a new RFC on the PCE architecture. RFC 4655 is titled "A Path Computation Element (PCE)-Based Architecture" The Abstract of this RFC reads as follows: Constraint-based path computation is a fundamental building block for traffic engineering systems such as Multiprotocol Label Switching (MPLS) and Generalized Multiprotocol Label Switching (GMPLS) networks. Path computation in large, multi-domain, multi-region, or multi-layer networks is complex and may require special computational components and cooperation between the different network domains. This document specifies the architecture for a Path Computation Element (PCE)-based model to address this problem space. This document does not attempt to provide a detailed description of all the architectural components, but rather it describes a set of building blocks for the PCE architecture from which solutions may be constructed. The RFC can be downloaded without charge from: http://www.ietf.org/rfc/rfc4655.txt We believe that this RFC will be of interest to you in your work on G.7715.2 and we would welcome any comments or questions about this RFC or any other issues related to PCE through our open mailing list.
