为了适应可实现性强、稳健性高的卫星光交换网络，选择模拟偏置时间光突发交换（E-OBS）作为转发卫星的激光通信架构，并结合现有的地面光交换资源预留方法，提出了一种偏置时间固定的资源预留机制。通过流量估计把突发数据按照目的地址和服务质量(QoS)区分为单个突发和突发流，按照分类对卫星光网络资源进行了成功预留，并建立了平均端-端时延、吞吐量、链路利用率、丢包率数学分析模型。理论分析与仿真证明，该资源预留方法通过突发流机制降低了光交换矩阵的重置时间和交换时延，通过E-OBS 架构降低了核心节点控制复杂度和对边缘节点的缓存需求，提高了网络吞吐量，适用于星载光交换网络。

To meet the requirements of satellite laser switching network, such as fine robustness and high physical realizability, emulated-optical burst switching (OBS) is selected as the architecture of relay satellite, and an on-board resource reservation protocol, whose offset time is constant, is proposed combining the ground resource reservation methods. Traffic prediction is used to differentiate the data burst into single burst or burst stream according to the destination and quality of service (QoS), then resource reservation is accomplished successfully. To validate it, mathematic models of mean end-end delay, throughput, link utility and burst loss probability are established. The results of analysis and emulation show that the protocol can reduce the reconfiguration time and switching time of optical switch matrix through burst stream scheme, and decrease the complexity and cache size requirement through the E-OBS architecture, so the new resource reservation protocol meets the requirements of satellite laser communication.
