This project aims at developing efficient algorithms for multicast communication within the optical networks based on Wavelength Division Multiplexing (WDM). The following research activities will be particularly pursued. First, the research team will work on the WDM simulators particularly suitable for multicast applications based on WDM. Effi-cient specific multicast tree construction problems will be formulated and their computa-tional complexity will be analyzed. Second, this project will include more general multi-cast problems and seek the appropriate solutions, such as when the set of senders and re-ceivers in the multicast group vary. Finally, a part of the research will be devoted to the problem of constructing multicast trees in heterogeneous networks with different optical node architectures as well as the fault-tolerance and Quality-of-Service (QoS) problems related to optical multicast built in existing Internet environment and with application-level requirements. This project will include undergraduate students in research and will thus have substantial impact on their preparation for graduate education as well as it will be conducted as means of creating awareness and interest among undergraduate students on the issues surrounding optical networks.

本项目旨在开发基于波分复用(WDM)的光网络中高效的组播通信算法。将特别开展以下研究活动。首先，研究小组将致力于开发特别适合基于WDM的组播应用的WDM模拟器。建立了有效的特定组播树构造问题，并对其计算复杂度进行了分析。其次，该项目将包括更一般的多播问题，并寻求适当的解决方案，例如当多播组中的发送者和接收者的集合变化时。最后，研究了在具有不同光节点体系结构的异质网络中构建组播树的问题，以及在现有Internet环境下构建具有应用层需求的光组播的容错性和服务质量(Qos)问题。该项目将包括正在研究的本科生，因此将对他们准备研究生教育产生重大影响，并将作为提高本科生对有关光纤网络问题的认识和兴趣的手段进行。
