A Batched Poisson Multirate Loss Model Supporting Elastic Traffic Under the Bandwidth Reservation Policy
The authors present a new loss model for the call-level analysis of a single link, which accommodates calls of different service-classes with elastic bandwidth requirements. Calls arrive in the link according to a Batch Poisson process, a process that can be used to model traffic, which is more 'Peaked' and 'Bursty' than the Poisson process. The available link bandwidth is shared to calls according to the Bandwidth Reservation policy, whereby they can guarantee certain Quality-of-Service for each service-class. In the proposed model, they assume a general batch size distribution and the Partial Batch Blocking discipline. According to this discipline, one or more calls of an arriving batch are accepted, while the rest are discarded, depending on the available link bandwidth.
