Service Level Agreement (SLA) is a contract between the Service Provider (SP) and the customer. Among various parameters, SLA imposes penalties on the SP when the customer's Quality-of-Service (QoS) requirements are violated. Hence, it is desirable to avoid SLA violations and such penalties. SLA also states the maximum amount of downtime a connection may tolerate during its lifetime. In this paper, the authors present a dynamic provisioning scheme called Preemption-Oriented SLA-Aware Provisioning (POSAP) for telecom mesh networks, which considers a connection's: availability requirements, penalty, and state.
