摘要:

针对网络故障恢复机制可以对可重构网络性能产生重要影响的实际情况,从理论上对可重构网络的运行状态进行分析,提出了一种可重构网络的可用性模型。该模型以节点服务能力和网络服务能力的量化描述为基础,通过引入可重构网络的状态转移理论,以有限状态马尔科夫链进行理论分析得到。通过仿真实验对该可用性模型的有效性进行验证,仿真结果表明,理论模型计算结果与仿真结果拟合性较好,可用于描述特定可重构网络的可用性能。

关键词: 可重构网络, 节点服务能力, 网络服务能力, 可用性模型

Abstract:

For network fault recovery mechanisms can have a significant impact on network performance reconfigurable actual situation theoretically analyze the running reconfigurable networks, a reconfigurable network availability model is proposed. In this model, quantitative description of the node service capabilities and network services capabilities, based on reconfigurable network by introducing state transition theory, finite-state Markov chain theoretical analysis. To verify the validity of the availability of the model by simulation, simulation results show that the theoretical model calculations and simulation results fit better, can be used to describe the specific performance reconfigurable networks available.

Key words: reconfigurable network, node service capability, network service capability, avaliability model
