非马尔可夫分组业务的有效带宽
Effective bandwidth of non-Markovian packet traffic
摘要:
我们展示了应用统计力学的最新进展,在电信工程中的一个问题:评估的通信信道的质量方面的罕见和极端的事件。特别是,我们讨论了非马尔可夫模型的电信业务在连续时间和部署的“克隆”过程的非平衡统计力学有效地计算其有效带宽。克隆方法使我们能够评估的性能,即使在没有分析结果,这往往是很难获得时,动态是非马尔可夫的流量协议。
英文摘要:
We demonstrate the application of recent advances in statistical mechanics to a problem in telecommunication engineering: the assessment of the quality of a communication channel in terms of rare and extreme events. In particular, we discuss non-Markovian models for telecommunication traffic in continuous time and deploy the "cloning" procedure of non-equilibrium statistical mechanics to efficiently compute their effective bandwidths. The cloning method allows us to evaluate the performance of a traffic protocol even in the absence of analytical results, which are often hard to obtain when the dynamics are non-Markovian.
