一种被用于网络管理的性能分析模型和实现

A Performance Analysis Model and Its Implementation for Network Management

为了提高网络的可靠性以及当今高速通信网络的管理水平 ,提出了一种用于网络管理的性能及可信度分析模型 .该模型能够实时地计算和预测网络的各个性能参数 (例如 ,带宽、吞吐量和延时等 )的可靠性 (per-formance- reliability)、可用性 (performance- availability)和该网络的平均无故障时间 (mean time to failure,简称MTTF)等 .由于此模型求真解十分复杂 ,对于高可靠性网络的管理 ,给出了该模型的近似模型及其实现 .

To improve network reliability and management level in today's high speed telecommunication networks, a performance and dependability analysis model used for network management is proposed in this paper, which computes in real time and forecasts performance reliability, performance availability for the overall network performance parameter (e.g. bandwidth, throughput and latency) and the MTTF (mean time to failure). Due to the arising complexity of exact model solution, for highly reliable network's management an approximation of the model and its implementation are also presented.
