描述了一种用于波分复用（WDM）光网络中光突发交换（OBS）的新型实时（JIT）信令协议的体系结构、设计和实现。JIT-OBS范例被设计用于跨光网络的数据突发的超低延迟单向传输。它结合了电路交换和分组交换的理想特性。它具有带外控制信号处理功能，消除了中间节点的数据突发缓冲，同时最大限度地减少了建立时间，并最大限度地提高了交叉连接带宽效率。我们提出并描述了JIT信令的体系结构，并分析了它的基本性能。我们提出了详细的信令消息设计，并讨论了基本原理和考虑，进入这个设计。我们描述和检查各种方案，说明操作的JIT信令协议（JIT-SP）在连接建立和拆除。最后，我们描述和总结的JIT信令软件原型在华盛顿，DC试验床网络下实施的MONET项目。
We describe the architecture, design, and implementation of a novel just-in-time (JIT) signaling protocol for optical burst switching (OBS) in wavelength division multiplexed (WDM) optical networks. The JIT-OBS paradigm is designed for ultra-low-latency unidirectional transport of data-bursts across an optical network. It combines the desirable features of circuit-switching and packet-switching. It features out-of-band control signal processing that eliminates buffering of data-burst at intermediate nodes, while minimizing the setup time, and maximizing the cross-connect bandwidth efficiency. We motivate and describe the architecture of JIT signaling, and analyze its basic performance. We present the detailed signaling message design and discuss the rationale and considerations that went into this design. We describe and examine various scenarios that illustrate the operations of the JIT signaling protocol (JIT-SP) in connection establishment and teardown. Finally, we describe and summarize the JIT signaling software prototype in the Washington, DC Testbed network implemented under the MONET project.
