This project investigates the static and dynamic partitioning of optical networks into domains or clusters and addresses the problem of providing survivable end-to-end service provisioning for unicast and multicast traffic over such multi-domain networks. A large optical network, even if administered by a single operator, needs to maintain its state information in a distributed and multi-domain hierarchy for purposes of scalability and fault-tolerance. Moreover, dynamic reconfiguration is often necessary to respond and adapt to sudden unexpected events or changes in network conditions. Other significant challenges in such a heterogeneous multi-domain environment are to implement end-to-end routing and survivability mechanisms, which are complicated by the limited amount of state information shared across domains due to factors related to business, policy, security, and other issues. This project enables a self-organizing framework for survivable optical networks. The project is addressing new methods for defining and reconfiguring domains based on service and performance requirements, introduces several new mechanisms for providing survivability in multi-domain networks, and is introducing new algorithms and protocols for provisioning survivable end-to-end unicast and multicast services in a scalable and cost-efficient manner. The broader impact of this work is that it can lead to a more robust and dynamic optical control layer that will enable the deployment of a greater range of end-to-end optical services to support emerging applications. It envisions greater intelligence in the control plane of optical transport networks, potentially leading to a network that is more autonomous than networks in existing ASON and GMPLS frameworks.

该项目调查了光网络到域或集群中的静态和动态分配，并解决了为多域网络上的单播和多播流量提供可生存的端到端服务提供的问题。即使由单个操作员管理，一个大型的光学网络也需要在分布式和多域层次结构中维护其状态信息，以实现可伸缩性和耐受性的目的。此外，对于响应并适应突然意外事件或网络条件中的变化，通常需要动态重新配置。在这种异质多域环境中，其他重大挑战是实施端到端的路线和生存机制，由于与业务，政策，安全性和其他问题相关的因素，由于与业务，政策，安全和其他问题相关的因素，跨领域共享的国家信息有限。该项目为可生存的光网络提供了一个自组织框架。该项目正在针对基于服务和性能要求定义和重新配置域的新方法，引入了多种新的机制，用于提供多域网络中的生存能力，并正在以可缩放和成本效益的方式为可生存的端到端单播和多播服务提供新的算法和协议。这项工作的更广泛的影响是，它可以导致更强大和动态的光学控制层，这将使部署更大范围的端到端光学服务以支持新兴的应用程序。它设想了光传输网络的控制平面中更大的智能，这可能导致网络比现有ASON和GMPLS框架中的网络更自治。
