U.S.-South Korea Cooperative Research on Fault Management in the Optical Internet Based on Optical Burst Switching

该奖项支持美国加州大学戴维斯分校博士后、研究生Biswanath Mukherjee教授访问韩国，与全北国立大学Kim Young-Chon教授及其研究小组合作开展光网络研究。这两个小组为他们的合作研究带来了互补的专业知识。Mukherjee教授从事光网络架构研究多年，在带宽供应（即电路交换）应用的生存性光网络方面具有特别的专业知识。金教授一直致力于光突发交换（OBS）网络的尖端研究。“光互联网”的概念正在迅速被接受。下一代光网络有望根据业务模式的变化，为用户提供更加灵活和动态的网络资源使用，并将支持互联网流量的快速增长。光网络在网络基础设施中光纤的深度渗透，以及产业界、大学、政府为实现“光互联网”的共同愿景而共同努力的韩国是一个高度优先考虑的问题。光突发交换与通用多协议标签交换（GMPLS）是满足未来骨干网带宽和灵活性要求的一种很有前途的方法。博士提出的合作研究。Mukherjee和Kim专注于可生存的网络架构和协议，可以对抗OBS网络中的各种类型的故障。到目前为止，这个话题在文献中很少受到关注。此外，联合研究工作将提供网络架构（Mukherjee）和设备功能（Kim）之间的紧密耦合。如果没有对设备功能和限制的充分了解，可能会产生不容易实现的架构；同样，在没有有用系统概念的情况下进行的新光学设备的研究，可能导致有限或无用的复杂技术。这项研究的更广泛的影响包括加强培训和国际经验的研究生参与。加州大学戴维斯分校的研究项目是为数不多的培养光网络（而不是光通信）专业博士的项目之一。拟议中的美韩研究合作将为这些研究生提供宝贵的培训，并为他们应对未来全球电信特别是光网络行业的挑战做好准备。

0323384MukherjeeThis award supports research visits by Professor Biswanath Mukherjee, a postdoctoral fellow, and a graduate student of the University of California at Davis, to collaborate in research on Optical Networks with Professor Young-Chon Kim and his research group of Chonbuk National University of Jeonbuk, Korea. The two groups bring complementary expertise to their collaborative research. Professor Mukherjee has worked in optical network architectures for many years, and has particular expertise in survivable optical networks for bandwidth provisioning (i.e., circuit switching) applications. Professor Kim has been conducting cutting-edge research on Optical Burst Switching (OBS) networks. The "Optical Internet "concept is gaining rapid acceptance. Next-generation optical networks are expected to provide users with more flexible and dynamic use of network resources according to the variation of traffic pattern and will support the rapid growth of Internet traffic. Optical networking is a high priority in Korea where there is deep penetration of fiber in the network infrastructure, and where industry, university, and government are working in unison to achieve the collective vision of the Optical Internet. Optical Burst Switching with Generalized Multi-Protocol Label Switching (GMPLS) is a promising approach to satisfy the bandwidth and flexibility requirements of future backbone networks. The collaborative research proposed by Drs. Mukherjee and Kim focuses on survivable network architectures and protocols that can combat various types of failures in OBS networks. This topic has received little attention in the literature so far. In addition, the joint research effort will provide tight coupling between network architectures (Mukherjee) and device capabilities (Kim). Without a sound knowledge of device capabilities and limitations, one can produce architectures that may not be easily realizable; similarly, research on new optical devices, conducted without the concept of a useful system, can lead to sophisticated technology with limited or no usefulness. The broader impacts of this research include enhanced training and international experience for the participating graduate students. The research program at UC Davis is one of very few that is producing PhD graduates with expertise in optical networking (as opposed to optical communications). The proposed US-Korea research collaboration will provide valuable training to these graduate students, and prepare them well to handle the challenges of the future global telecommunications in general and the optical networking industry in particular.
