Hi all, A new version (03) of PCE Global Concurrent Optimization (GCO) draft has been published as below. Manageability Section has been updated with the revision. Any comments and suggestions are appreciated. Thanks. Young ---------------------------------------------------------------------------- --------- A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Path Computation Element Communication Protocol (PCECP) Requirements and Protocol Extensions In Support of Global Concurrent Optimization Author(s) : Y. Lee, et al. Filename : draft-lee-pce-global-concurrent-optimization-03.txt Pages : 32 Date : 2007-4-25 The Path Computation Element (PCE) is a network component, application, or node that is capable of performing path computations at the request of Path Computation Clients (PCCs). The PCE is applied in Multiprotocol Label Switching Traffic Engineering (MPLS-TE) networks and in Generalized MPLS (GMPLS) networks to determine the routes of Label Switched Paths (LSPs) through the network. The Path Computation Element Communication Protocol (PCEP) is specified for communications between PCCs and PCEs, and between cooperating PCEs. When computing or re-optimizing the routes of a set of LSPs through a network it may be advantageous to perform bulk path computations in order to avoid blocking problems and to achieve more optimal network- wide solutions. Such bulk optimization is termed Global Concurrent Optimization (GCO). A Global Concurrent Optimization is able to simultaneously consider the entire topology of the network and the complete set of existing LSPs, and their respective constraints, and look to optimize or re-optimize the entire network to satisfy all constraints for all LSPs. This document provides application-specific requirements and the PCEP extensions in support of a global concurrent path computation application.

Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-lee-pce-global-concurrent-optimization-03.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv at ietf.org. In the body type: "FILE /internet-drafts/draft-lee-pce-global-concurrent-optimization-03.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. <ftp://ftp.ietf.org/internet-drafts/draft-lee-pce-global-concurrent-optimiza tion-03.txt> <ftp://ftp.ietf.org/internet-drafts/draft-lee-pce-global-concurrent-optimiza tion-03.txt> _______________________________________________ I-D-Announce mailing list I-D-Announce at ietf.org https://www1.ietf.org/mailman/listinfo/i-d-announce
