Hi, 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 passive fashion. The authors would now like to solicit
comments among the performance metric experts, regarding the structure of the
document and the definition of the metrics. 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
help. Title: Label Switched Path (LSP)

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 is: http://www.ietf.org/internet-drafts/draft-ietf-ccamp-lsp-dppm-01.txt Best regards, Weiqiang |
