中文摘要：
根据卫星光交换网络应用需求,结合现有的地面光突发交换资源预留方法,提出了一种基于突发流的资源预留协议。首先通过流量估计把突发数据按照目的地址和QoS区分为单个突发和突发流,然后按照这两种分类对卫星光网络资源进行了成功预留。为了对该预留方法进行考察,建立了平均端-端时延、吞吐量、链路利用率数学分析模型。理论分析与仿真证明了该资源预留方法通过降低光交换矩阵的重置时间和交换时延,有效降低了端-端时延,提高了网络吞吐量,适用于星载光交换网络。
英文摘要：
According to resource reservation protocol the requirements of satellite laser based on data burst stream was switching network, an on-board proposed combining the ground resource reservation methods. First, traffic prediction is used to differentiate the data burst into single burst or burst stream according to the destination and QoS. Then resource reservation is accomplished successfully. To validate it, mathematic model of mean end-end delay, throughput and link utility is established. From the comparison results of analysis and emulation, the protocol performance is better than other methods by lowering the reconfiguration time and switching time of optical switch matrix, so the new resource reservation protocol meets the requirements of satellite laser communication.
