摘要
为了刻画通信网络中自动请求重发(automatic repeat request,ARQ)通信协议,将其模型化转为一个带有启动时间的GI/G/1排队系统。首先建立了服务员的闲期所满足的上下界函数关系,后利用此关系证明了该排队系统队长、负荷和忙期过程的扩散逼近,近似刻画了系统指标。
A GI/G/1 queue with setup times was modeled to describe the automatic repeat request (ARQ) protocol in communication network. First, a functional lower and upper bound for the idle time was constructed, and then the bound relation was used to obtain the diffusion approximations for the queue length, workload and busy time processes.
