OBS核心路由器中一种改进的数据输出模型研究

Performance analysis of an improved date outputted model in an OBS core router

在光突发交换核心路由器中,突发数据分组的输出特性会影响路由器的输出性能。给出了一种改进的基于多概率输出环境的突发数据分组输出模型并进行了研究。改进的数据输出模型根据不同目的地路径长短而选择输出概率,更符合实际网络运行情况。对分组阻塞率、系统通过率等性能参数进行了分析和讨论。

In optical burst switching core routers,bursts outputted process could affect the performance of system.In this paper,an improved burst-outputted model based on multi-probability outputting has been proposed and analyzed.The proposed model is more fit for real network running scenario under the consideration that,a burst select output-port is accord on the path length to destination.Burst blocking probability,system passing rate are evaluated and discussed.
