摘要： Dynamic restoration involves routing and bandwidth assignment of an unplanned restoration path in a wavelength switched optical network (20), having regeneration nodes (60), nodes each having a ROADM (62) having drop paths and add paths. An electrical switch (68) provides configurable regeneration capacity by coupling selected drop paths to selected add paths. Some of the configurable regeneration capacity is kept for unplanned restoration paths. A PCE determines (120) routing and bandwidth assignments for an unplanned restoration path for the traffic flow to avoid a fault, and sends (130) configuration messages to the nodes to set up the unplanned restoration path dynamically and to configure the electrical switch to provide regeneration on the path. Keeping some reconfigurable regeneration capacity enables much longer unplanned paths to be found to avoid faults, and enables wavelength conversion if needed. Thus the reliability of finding at least one path avoiding the fault can be increased.

摘要： Techniques for providing closed-loop control and predictive analytics in packet-optical networks are described. For example, an integrated, centralized controller provides tightly-integrated, closed-loop control over switching and routing services and the underling optical transport system of a communication network. In one implementation, the controller includes an analytics engine that applies predictable analytics to real-time status information received from a monitoring subsystem distributed throughout the underlying optical transport system. Responsive to the status information, the analytics engine applies rules to adaptively and proactively identify current or predicted topology-changing events and, responsive to those events, maps reroutes packet flows through a routing/switching network and control and, based on any updated bandwidth requirements due to topology changes, dynamically adjusts allocation and utilization of the optical spectrum and wavelengths within the underlying optical transport system.

摘要： A network and method of operating the network, the network comprising a transport layer that includes first and second disjoint but topologically substantially identical subnetworks A and B, each having a plurality of optical switch nodes and/or reconfigurable optical add-drop multiplexer (ROADM) nodes, and a routing layer wherein each router is coupled to at least one node in A and at least one node in B. The network is operable to provide a plurality of classes of services providing corresponding Quality of Service, and the routing layer or routing/transport interface can differentiate between traffic having different classes of service and schedule the traffic based on its service class. In the case either of the subnetworks becomes inoperable, all of the traffic is transferred to the other subnetwork, and the QoS of the classes of service is maintained by scheduling traffic to increase the delay experienced by delay-tolerant traffic.

摘要： This disclosure introduces a significant extension to the method of p-cycles for network protection. The main advance is the generalization of the p-cycle concept to protect multi-span segments of contiguous working flow, not only spans that lie on the cycle or directly straddle the p-cycle. This effectively extends the p-cycle technique to include path protection, or protection of any flow segment along a path, as well as the original span protecting use of p-cycles. It also gives an inherent means of transit flow protection against node loss. We present a capacity optimization model for the new scheme and compare it to prior p-cycle designs and other types of efficient mesh-survivable networks. Results show that path-segment-protecting p-cycles (“flow p-cycles” for short) have capacity efficiency near that of a path-restorable network without stub release. An immediate practical impact of the work is to suggest the of use flow p-cycles to protect transparent optical express flows through a regional network.
摘要翻译：本公开引入了用于网络保护的p循环的方法的显着扩展。主要的进展是p循环概念的泛化，以保护连续工作流程的多跨段，不仅跨越循环或直接跨越p循环。这有效地扩展了p循环技术，包括路径保护，或保护沿着路径的任何流动段，以及保护p循环使用的原始范围。它还提供了针对节点丢失的传输流保护的固有方法。我们提出了新方案的容量优化模型，并将其与先前的p周期设计和其他类型的高效网状生存网络进行比较。结果表明，路径段保护p循环（简称“流动p循环”）具有接近可用路径恢复网络的容量效率，而不存在分支释放。这项工作的直接实际影响是建议使用流量p循环来保护通过区域网络的透明光学快速流通。
