Abstract
Outage measurement is an integral part of high-availability network operations to assess and report the availability of router components and, in turn, the availability of the network. This paper presents a novel approach to the outage measurement, called Component Outage On-Line (COOL) measurement. COOL provides an autonomous real-time outage measurement within the router. It automates the outage measurement process and makes it more accurate, reliable, scalable, and cost-effective. This paper describes COOL's measurement methodology with respect to outage model, measurement metrics, architectural framework, methods for measuring hardware and software outages and planned and unplanned outages, and outage MIB design. COOL is being implemented in various network routers. Experiment results on COOL run-time performance are presented.
