Queueing System with Two Different Service Speeds

摘要

In the paper, the author considers an M/M/1 queueing system in which the servercan serve at two different speeds. The speed of the server is regulated by the content of a credit buffer. The performance measures of interest are the sojourn time distribution of customers and the joint distribution of the content of the waiting room and the content of the credit buffer. This system is a simple model for a traffic regulation scheme (two-level traffic shaper) at the edge of an ATM network. Numerical results are presented which demonstrate that effect of the regulation scheme.
