Hi, Dear PCErs, We've just posted a new I-D about PCEP extension for stateful PCE usage in GMPLS networks. You could find the I-D here: http://www.ietf.org/internet-drafts/draft-zhang-pce-pcep-stateful-pce-gmpls-00.txt
Your feedbacks and comments would be very much appreciated. Best Regards, Xian et al. -----邮件原件----- 发件人: internet-dra...@ietf.org [mailto:internet-dra...@ietf.org] 发送时间: 2012年7月9日 10:00 收件人: Zhangxian (Xian) 抄送: ogon...@tid.es; ramon.casel...@cttc.es; Leeyoung 主题: New Version Notification for draft-zhang-pce-pcep-stateful-pce-gmpls-00.txt A new version of I-D, draft-zhang-pce-pcep-stateful-pce-gmpls-00.txt has been successfully submitted by Xian Zhang and posted to the IETF repository. Filename: draft-zhang-pce-pcep-stateful-pce-gmpls Revision: 00 Title: Path Computation Element (PCE) Protocol Extension for Stateful PCE Usage in GMPLS Networks Creation date: 2012-07-07 WG ID: Individual Submission Number of pages: 15 URL: http://www.ietf.org/internet-drafts/draft-zhang-pce-pcep-stateful-pce-gmpls-00.txt Status: http://datatracker.ietf.org/doc/draft-zhang-pce-pcep-stateful-pce-gmpls Htmlized: http://tools.ietf.org/html/draft-zhang-pce-pcep-stateful-pce-gmpls-00 Abstract: The Path Computation Element (PCE) facilitates Traffic Engineering (TE) based path calculation in large, multi-domain, multi-region, or multi-layer networks. PCE can be stateless or stateful. With the LSP state information acquired from the network, a stateful PCE exhibits superiority in facilitating a wide variety of applications, especially in GMPLS networks, such as impairment-aware routing and wavelength assignment in wavelength-switched optical networks (WSON), time-based scheduling applications. This memo provides extensions required for PCE communication protocol (i.e. PCEP) so as to enable the usage of a stateful PCE capability in GMPLS networks. To be more specific, the PCEP extensions specified in this memo include not only new objects but also modification of existing objects in PCEP messages, with regard to stateful PCE usage in GMPLS networks.
