| Abstract | In today's telecommunication networks, it's well known that unexpected
failures in the physical links may cause significant loss or interruption of services. It's
desirable if the deterioration of links can be recognized early and maintenance is taken
before the failure occurs. The main objective of monitoring strategy is to detect any
performance degradation of the monitored component in order to prevent unexpected
failures. Recently, ATM-based networks have been recommended as the future
universal networks. However, there is very little research on performance monitoring
of ATM-based networks. Hence, modified from Kubat's continuous monitoring model
(1992), this research presents a continuous-monitoring model for a general ATM
network whose branches are slowly deteriorating. The performance index of the links
is BER index. Due to multiple-service characteristics of ATM-based networks, several
BER indexes of respective services are continuously monitored under certain routing
protocols proposed by Hwang and Kurose (1991). If one or more BER index exceeds
its individual action limit (optimal BER index), the repair procedure is initiated. The
action limit is derived so that the long run average maintenance cost is minimized.
Some numerical examples are given to illustrate the proposed model and the
optimization results |
