0626741卡迈勒高性能网络预计将支持具有一对多、多对一和多对多等多点业务类型的应用。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，因此通常在同一波长上疏导几个流。因此，在有效支持此类流量的同时，以成本最优的方式设计此类网络非常重要。本课题是针对多点业务量疏导的抗毁光网络的设计和分析。该项目考虑了支持多点业务疏导的业务复用设备的设计。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施成本、增强网络流量处理能力和支持网络可生存性。同时考虑了静态和动态交通条件。对于静态交通条件下的网络设计和运营，将开发出最优和准确的启发式方法。在动态业务条件下，考虑多点会话的动态提供，取决于资源的可用性，以及会话和会话内的用户的动态性质，并将开发促进该提供的算法。这项研究的更广泛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高效地支持高性能应用。它还包括对学生进行光网络领域的培训，以及加强现有的和开设新的研究生和高级本科课程。

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.
