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

0001579Saadawi描述：该奖项旨在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大学计算机科学系M. Nazih El-Derini博士的合作项目。该项目旨在提供一种体系结构，该体系结构支持使用本地注册移动IP协议分层组织的主机的互联网协议（IP）多播。移动IP （M-IP）协议允许IP主机在不同的网络之间移动，而不需要破坏已建立的会话。引入支持本地注册的M-IP系统是为了减少需要与远程定位的本地代理进行本地注册的次数。在多播组成员位置频繁变化的环境中，提供一个支持IP多播的高效系统是提供移动性支持的一个挑战。还将介绍与本地注册M-IP系统中的容错相关的问题，以及建议的方法来增强此类系统对本地代理和外国代理故障的鲁棒性。仿真结果描述了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具有重要的专业知识。埃及PI在多媒体网络和信息网络领域也有丰富的经验。他建立了中东地区最大的计算机网络之一。两位科学家根据各自的能力和设备分配了任务和责任。预计此次合作将使双方研究人员受益，并有助于埃及不断扩大的互联网提供商行业。一名纽约市立大学城市学院的博士后研究员将参与这个项目。该提案符合INT在共同感兴趣的领域支持合作研究的目标。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，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.
