Although the authors did not ask the advice of the pmol
working group, I guess that they could get valuable inputs here as well.

From: bmwg-bounces at ietf.org [mailto:bmwg-bounces at ietf.org] On Behalf Of Weiqiang Sun Sent: Thursday, May 29, 2008 11:44 AM To: ippm at ietf.org; bmwg at ietf.org Cc: 'Rajiv Papneja'; 'gjhhit'; 'zhangguoying'; sunwq at sjtu.edu.cn; 'Bin Gu'; 'xqwei'; 'blithe' Subject: [bmwg] Soliciting comments on GMPLS performance metrics draft inCCAMP Hi IPPMers and
BMWGers, Recently the LSP dynamic provisioning
performance draft is adopted as a working item of CCAMP. The draft, abstract
shown below, defines a set of metrics to characterize the performance of a
signaling protocol in the control plane, which normally runs on top of a packet
switched control network. The draft proposes the metrics be tested in an active
fashion. It also proposes that some of the metrics be implemented in an online
or be collected passively. The authors would now like to solicit
comments among the performance metric experts, as this document contains
notations that are commonly seen in IPPM and BMWG. The authors believe that your
expertise can help us further improve this document, with regard to the
definition of the metrics and the structure as well. Please send your comments
directly to the authors, or, to the CCAMP working group mail list (ccamp at ops.ietf.org). We do appreciate your
input. Title: Label Switched Path (LSP)

Generalized Multi-Protocol Label
Switching (GMPLS) is one of the most promising candidate technologies for the
future data transmission network. The GMPLS has been
developed to control and cooperate different kinds of network elements, such
as conventional routers, switches, Dense Wavelength Division
Multiplexing (DWDM) systems, Add- Drop Multiplexors (ADMs), photonic
cross-connects (PXCs), optical cross-connects (OXCs), etc. Dynamic
provisioning ability of these physically diverse devices differs from
each other drastically. At the same time, the need for dynamically
provisioned connections is increasing because optical networks are
being deployed in metro area. As different applications have varied
requirements in the provisioning performance of optical
networks, it is imperative to define standardized metrics and
procedures such that the performance of networks and application needs can be
mapped to each other. This document provides a series of
performance metrics to evaluate the dynamic LSP provisioning performance
in GMPLS networks, specifically the dynamical LSP
setup/release performance. These metrics can depict the features of the
GMPLS network in LSP dynamic provisioning. They can also be used
in operational networks for carriers to monitor the control plane
performance in realtime. A URL for this Internet-Draft
