项目摘要

Optical Networks have been expecting for promising high-speed network for applications require a high data transmission rate, low error rate and low delay. In this research, we proposed new optical network architecture for high-speed photonic network which is implemented by all photonic devise. First, we invented the recursive network architecture for non-blocking optical switches and showed that the recursive switch architecture had the good network performance as well as the simple control strategy of self-routing.We also invented the multi-stage optical switch architecture which has good properties of non-block and crosstalk free. The multi-stage optical switch architecture is a good choice for constructing non-blocking optical switch networks with low signal loss and crosstalk.Banyan networks with optical switches that are very attractive for serving as the optical switch architectures due to their nice properties of small depth and absolutely signal loss uniformity. We investigated the stacked vertically stacked optical banyan which is combining the horizontal expansion and vertical stacking of optical banyan networks. We have showed that the horizontally expanded and vertically stacked optical banyan networks usually have good properties of non-block and crosstalk free. Also, we study on the blocking behavior analysis and show that the proposed method is an effective approach to studying network performance and finding a graceful compromise among hardware cost, network depth, and blocking probability.Finally, we study the high survival network systems using a new restoration strategy which achieves the higher restoration performance than proactive restoration. We invented the active restoration strategy to compensate the switch node faults and link faults and achieve the high-survival performance for a large scale networks.

由于光网络对数据传输速率、误码率和时延的要求很高，因此光网络被认为是一种很有前途的高速网络。在这项研究中，我们提出了一种新的高速光子网络光网络架构，该架构由全光子设备实现。首先，我们提出了无阻塞光开关的递归网络结构，证明了递归网络结构具有良好的网络性能和简单的自路由控制策略，并提出了具有良好的无阻塞和无串扰特性的多级光开关结构。多级光开关架构是构建低信号损耗和串扰的无阻塞光开关网络的良好选择。带有光开关的Banyan网络具有深度小和绝对信号损耗均匀性的良好特性，非常适合用作光开关架构。研究了光学榕树网络的水平扩展和垂直叠加相结合的垂直叠加光学榕树网络。我们已经证明了水平扩展和垂直堆叠的光学榕树网络通常具有良好的无阻塞和无串扰特性。研究了阻塞行为分析，表明该方法是研究网络性能的一种有效途径，可以在硬件开销、网络深度和阻塞概率之间找到一个合适的折衷方案。最后，研究了高生存率网络系统的一种新的恢复策略，该策略的恢复性能优于主动恢复。我们提出了主动恢复策略，以补偿交换节点故障和链路故障，实现大规模网络的高生存性能。
