在本文中，我们开发了一个分析模型，以评估光突发交换（OBS）节点的性能与光级缓冲区重传阻塞的突发。首先，目前使用的突发阻塞模型和建模的光缓冲区在OBS节点被证明是不合适的作为一个阻塞模型在OBS节点中的重传。因此，我们提出了一个新的阻塞模型的突发传输机制与重传技术在光级缓冲光突发交换节点。从数值分析中，我们显示了性能的增强，通过应用光缓冲器的突发阻塞概率和链路利用率方面的阻塞突发的重传。
In this paper, we develop an analytical model to evaluate the performance of optical burst switching (OBS) node with optical-level buffers for retransmission of blocked bursts. First, currently used burst blocking models and modelling of optical buffers at OBS nodes are shown to be inappropriate as a blocking model for retransmission in OBS nodes. Thus, we propose a new blocking model for the burst transmission mechanism with retransmission technique in an optical-level buffered OBS node. From the numerical analysis, we show the performance enhancement by applying optical buffers for retransmission of blocked bursts in terms of burst blocking probability and link utilization.
