项目摘要

The research is intended to show a Dynamic, Wide-area Resource Operation and Management Scheme for a Full-optical Networks, and the research also evaluates its performance improvement on safety and reliability of the network During the research period, we have conducted the followings;(1) Dynamic protection/restoration scheme for the full-optical network is proposed, and the efficiency of the resource utilization is shown.(2) The Path Computation Element (PM which is an integrated resource management entity is developed, and by conducting feasibility demonstration together with the photonic cross-connects (PXCs), optical transmission system and IP routers, significant improvement of safety, reliability and communication quality are shown.(3) The Border Model, which is our proposal for the control plane to make possible integration of IP and optical domain as well as the integration of IP layer and lower layers, is implemented on network components, and is the candidate to realize smooth integration of existing IP networks and future full-optical networks.(4) Major results of the study are published at internationally recognized societies and conferences.In the last year of the study, we have conducted the standardization effort for the NGN related standard development at the ITU-T and IETF. One of the fruit of the efforts is the acceptance of our concept in ID Management' standard which is one of the basic elements of the NGN management, as well as service development for Ubiquitous networks. Finally, we have concluded the study with the significant success and have presented the final report.

本研究旨在提出一种全光网络的动态广域资源操作和管理方案，并评估其在网络安全性和可靠性方面的性能改进。在研究期间，我们进行了以下工作：（1）提出了全光网络的动态保护/恢复方案，并展示了其资源利用效率。(2)开发了综合资源管理实体--路径计算单元（PM），并与光交叉连接（PXC）、光传输系统和IP路由器一起进行了可行性论证，表明其安全性、可靠性和通信质量得到了显著提高。(3)边界模型是我们为实现IP与光域的融合以及IP层与下层的融合而提出的控制平面方案，在网络组件上实现，是实现现有IP网络与未来全光网络平滑融合的候选方案。(4)研究的主要结果已在国际认可的学会及会议上发表。在研究的最后一年，我们已在ITU-T及IETF进行有关NGN相关标准发展的标准化工作。这些努力的成果之一是我们在ID管理标准中的概念被接受，这是NGN管理的基本要素之一，也是普适网络服务开发的基本要素之一。最后，我们总结了研究的重大成功，并提出了最终报告。
