A discrete-time queueing model of EMD policy in high-speed networks

摘要

In this paper, we consider a discrete-time queue for the Early Message Discarding (EMD) policy in high-speed networks under bursty arrival. This system is analyzed as a quasi-birth-and-death (QBD) process. We derive the steady-state probability distribution of buffer content by using generating-functions approach. Finally, we obtain the useful performance measure—goodput ratio and give some numerical results.
