US-Egypt Cooperative Research: Multicast Mobile Internet Protocol with Fault Tolerance Support.

0001579 SaadawiDescription：该奖项是为了支持纽约城市大学城市学院电气工程系Tarek Saadawi博士和埃及亚历山大市亚历山大市大学计算机科学系M.Nazih El-Derini博士开展的一个合作项目。该项目旨在提出一种体系结构，该体系结构支持使用分层组织上的本地注册移动IP协议的主机的互联网协议(IP)组播。移动IP(M-IP)协议允许IP主机在不同网络之间移动，而无需中断已建立的会话。引入了支持本地注册的M-IP系统，以减少需要向远程归属代理进行归属注册的次数。对于提供移动性支持的系统来说，在多播组成员频繁改变其位置的环境中提供支持IP多播的高效系统是一个挑战。还将介绍与本地注册M-IP系统中的容错相关的问题，以及建议的增强这种系统对本地代理和外地代理故障的稳健性的方法。仿真结果将描述所建议的容错机制的性能以及理论分析。范围：美国PI在信息网络和电信以及多媒体网络领域拥有丰富的专业知识。埃及和平协会在多媒体网络和信息网络领域也拥有丰富的经验。他建立了中东最大的计算机网络之一。两位科学家根据自己的能力和设施分配了任务和责任。预计这一合作将使研究人员和埃及不断扩大的互联网提供商行业受益。纽约州立大学城市学院的一名博士后研究员将参与这个项目。这一建议符合INT支持在共同感兴趣的领域进行合作研究的目标。该项目得到了美国-埃及联合基金计划的支持，该计划为两国的科学家和工程师提供资助，以开展这些合作活动。

0001579SaadawiDescription: This award is to support a collaborative project by Dr. Tarek Saadawi, Department of Electrical Engineering, the City College of the City University of New York, and Dr. M. Nazih El-Derini, Department of Computer Science, Alexandria University, Alexandria, Egypt. The project is intended to present an architecture that supports Internet Protocol (IP) multicast for hosts using the local registration Mobile-IP protocol over hierarchical organization. The Mobile-IP (M-IP) protocol allows IP hosts to move between different networks without the need to tear down established sessions. The M-IP systems supporting local registration were introduced to reduce the number of times when home registration with the remotely located home agent is needed. Providing an efficient system that supports IP multicast in an environment where the multicast group members frequently change their location is a challenge for system providing mobility support. Also to be presented will be the issues associated with fault tolerance in local registration M-IP systems, as well as suggested approaches to enhance the robustness of such systems against both Home Agent and Foreign Agent failures. Simulation results describing the performance of the suggested fault tolerance mechanisms as well as theoretical analysis will be presented.Scope: The US PI has significant expertise in information networking and telecommunications, and in the area of multimedia networking. The Egyptian PI also has vast experience in the area of multimedia networking and information networking. He has built one of the largest computer networks in the Middle East. The two scientists have distributed tasks and responsibilities according to their capabilities and facilities. It is expected that the collaboration will benefit both researchers and help Egypt's expanding Internet Providers industry. A postdoctoral investigator at CUNY-City College will be involved in this project. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
