Summary:
We consider a multirate loss system that accommodates Poisson arriving calls of many service-classes with cooperative and non-cooperative users. “Cooperative" users can retry to be connected in the system with a reduced bandwidth, when they are blocked with their initial peak-bandwidth requirement. This behavior increases the quality of service perceived by other users. Due to the existence of retrials, the system model does not have a product form solution for the steady state distribution. However, we propose an efficient calculation of system’s occupancy distribution and Call Blocking Probabilities (CBP), while avoiding complex state space enumeration and processing. The proposed recursive formula is consistent and quite accurate, as it is shown through simulation. As a reference (for comparison), we use the conventional trunk reservation control for CBP equalization.
