Abstract
We model the time and network element failure dynamics of
network operators' service level agreement (SLA) risks.
This involves identification of events interrupting
service and stochastic modeling of failure events. The
key concepts are modeling how a service builds from
simple network components and the approximation of
interval availability, when failures are rare and the SLA
tracking period is in month/year scale. The dynamic
SLA-risk gives rise to a component importance measure,
which prioritizes repairs or indicates the importance of
operability of a component in terms of SLA-risk in the
current network and SLA state. Our work can be used in
network planning and OAM.
