摘　　要：在传统ON/OFF流量模型基础上,通过修改恒定速率假设为随机速率以及增加突发到达分布条件,新提出了一种增强的ON/OFF流量模型,克服了传统ON/OFF模型不能描述流量随时间动态分布的缺点。给出了任意时刻模型的流量分布式和均值表达式,并对泊松到达的突发推导出了便于计算的公式,仿真表明结果正确。Based on classic ON/OFF traffic model, a new enhanced ON/OFF traffic was introduced by revising constant traffic rate into random rate and adding a premise on burst arrival distribution, which overcame the defect in classic ON/ OFF traffic model that the traffic distribution is static and can not describe the variation dynamically. The traffic distribution and mean traffic expression of enhanced ON/OFF traffic model were analyzed and given. Computable simplified formulations for poisson arrival were also deduced. Simulation testified the result.
