Abstract :
The estimation of the expected traffic loss ratio (workload loss ratio, WLR) is a key issue in provisioning quality of service in packet based communication networks. In this paper we define a calculus for communication networks which is suitable for workload loss estimation based on the original definition of stationary loss ratio. Our novel calculus is a stochastic extension of the deterministic network calculus, which takes an envelope approach to describe arrivals and services for the quantification of resource requirements in the network.
