鉴于光网络技术所取得的重大进展和预期的持续进步，构建本地支持突发 IP 数据报的未来光互联网变得很有吸引力。突发交换 WDM 光网络被认为是未来光互联网骨干网的合适网络架构。然而，光处理能力的缺乏导致突发阻塞概率增加，进而导致网络性能非常有限。因此，有效的争用解决方法是必要的。基于对最新光学技术发展水平的讨论，提出了突发光学偏转路由协议。这种方法的想法是使用空闲光链路作为光纤延迟线来解决争用。仿真结果表明，该协议是有效降低突发交换WDM光网络阻塞概率、提高性能的有效解决方案。
Given the significant progress made and the continuing advances expected in the optical networking technology, it becomes attractive to build a future Optical Internet that natively supports bursty IP datagrams. Burst switching WDM optical networks are touted as suitable network architectures for future Optical Internet backbones. However, the lack of optical processing capabilities results in increased burst blocking probability, which in turn leads to very limited network performance. Efficient contention resolution method is therefore necessary. Based on discussions of the state of the art of recent optical technologies, a burst optical deflection routing protocol is proposed. The idea of this approach is to use idle optical links as fiber delay lines for contention resolution. Simulation results show that the proposed protocol is available solution for effectively reducing the blocking probability and increasing the performance of burst switching WDM optical networks.
