0626741 KamalHigh-performance networks are expected to support applications with multipoint traffic type, e.g., one-to-many, many-to-one and many-to-many. Since high-performance networks usually employ optical network infrastructures, and since most applications require sub-wavelength bandwidth, several streams are usually groomed on the same wavelength. It is therefore important that such networks be designed in a way that is optimal in terms of cost, while effectively supporting this type of traffic. This project deals with the design and analysis of survivable optical networks for multipoint traffic grooming. The project considers the design of the traffic multiplexing equipment to support multipoint traffic grooming. It also investigates the use of network coding and its implementation in such devices, and how such a technique can be used to reduce network implementation cost, enhance network traffic handling capabilities, and support network survivability. Both static and dynamic traffic conditions are considered. Optimal as well as accurate heuristic approaches will be developed for network design and operation under static traffic conditions. Under dynamic traffic conditions, the dynamic provisioning of multipoint sessions, subject to the availability of resources, and the dynamic nature of sessions and users within sessions is considered, and algorithms to facilitate this provisioning will be developed. The broader impact of this research includes the development of algorithms, which can be used by network designers and operators to support high performance applications efficiently. It also includes training of students in the area of optical networks, as well as enhancing existing and creating new graduate and senior undergraduate-level courses.

预计高性能网络将支持具有多点业务类型的应用，例如，一对多、多对一和多对多。由于高性能网络通常采用光网络基础设施，并且由于大多数应用需要亚波长带宽，因此多个流通常在同一波长上进行修整。 因此，重要的是，这种网络的设计在成本方面是最佳的，同时有效地支持这种类型的流量。 本计画主要研究多点流量疏导之可生存光网路之设计与分析。 该项目考虑了流量复用设备的设计，以支持多点流量疏导。 它还研究了网络编码的使用及其在此类设备中的实现，以及如何使用这种技术来降低网络实现成本，增强网络流量处理能力，并支持网络生存性。 静态和动态的交通条件被认为是。 最佳以及准确的启发式方法将开发静态交通条件下的网络设计和运营。 在动态交通条件下，多点会话的动态配置，资源的可用性，以及会话和会话内的用户的动态性质被认为是，和算法，以促进这种配置将被开发。 这项研究的更广泛的影响包括算法的开发，网络设计人员和运营商可以使用这些算法来有效地支持高性能应用。 它还包括在光网络领域培训学生，以及加强现有的和创建新的研究生和高年级本科生课程。
