我们对光突发交换 (OBS) 网络的 JIT、JET 和 Horizon 波长预留方案进行了详细分析。我们的分析考虑了几个重要参数，包括突发偏移长度，以及与突发在网络中传输时相关的光交换和硬件处理开销。我们工作的贡献包括：（i）JET 和 Horizon（在单个 OBS 节点上）的分析模型比以前发布的模型更准确，并且对于一般突发长度和偏移长度分布有效； (ii)确定参数值的区域，其中较复杂的预留方案简化为较简单的方案。我们比较了在不同参数值组下单个 OBS 节点上三种波长预留方案的性能。我们的主要发现是，在对光开关和电子硬件技术当前和未来最先进技术的合理假设下，JIT 的简单性似乎超过了 Horizon 和 JET 的任何性能优势。
We present a detailed analysis of the JIT, JET, and Horizon wavelength reservation schemes for optical burst switched (OBS) networks. Our analysis accounts for several important parameters, including the burst offset length, and the optical switching and hardware processing overheads associated with bursts as they travel across the network. The contributions of our work include: (i) analytical models of JET and Horizon (on a single OBS node) that are more accurate than previously published ones, and which are valid for general burst length and offset length distributions; and (ii) the determination of the regions of parameter values in which a more complex reservation scheme reduces to a simpler one. We compare the performance of the three wavelength reservation schemes on a single OBS node under various sets of parameter values. Our major finding is that, under reasonable assumptions regarding the current and future state-of-the-art in optical switch and electronic hardware technologies, the simplicity of JIT seems to outweigh any performance benefits of Horizon and JET.
