摘要
研究具有两类信元的带优先权的M/M/1排队系统。两类信元到达为相互独立泊松过程,两类信元分别在各自有限的缓冲区中排队,第一类信元较第二类信元具有强占优先权,同时第一类信元是不耐烦的。笔者采用矩阵分析的方法给出了两类信元各自的稳态分布,并作了相应的性能分析。
A M/M/1 queueing system with two kinds of cells and one kind of priority is studied. The arrival processes of the two kinds of cells are all Poisson processes. After entering the system,each cell queues in its finite capcity buffer. We assume the first kind of cell has the preemptive priority on the second kind of cell,and the first kind of cells is impatient. By using matrix analysis, we give steady-state distribution and make some performance evaluations for the two kinds of cells.
