摘要： The present invention provides systems and methods to mix In-Band (IB) and Out-of-Band (OOB) signaling mechanisms under the Private Network-to-Network (PNNI) protocol for optical control plane connectivity. The present invention provides mechanisms for establishing and controlling OOB control plane communications. By default, the mechanisms treat all links as IB to discover nodes and links using IB mechanisms. For any blocked links, the link can be configured as OOB if there is a data communication network (DCN) connection to the remote node.

摘要： Apparatuses and methods for merging multiple domains into a merged domain and splitting a single domain into multiple domains in an Automatically Switched Optical Network (ASON) are disclosed. For merging, a node in a first domain can be identified to be a new Routing Controller (RC) for the merged domain. A second domain can be identified to be merged with the first domain. Nodes, including old RCs, in the first domain and the second domain are notified of the identity of the new RC in the merged domain. The topology of the old RC's domain is sent to the new RC. The new topology is computed by the new RC from the topology information given by the old RCs. The updated topology is distributed to nodes in the merged domain via the new RC.

摘要： Embodiments of the present invention provide a method and system for reserving a connection's home path resources and restoring the connection on a link that includes a reserved priority bandwidth. A bandwidth advertisement indicating that the reserved priority bandwidth is available is analyzed and a restoration request requesting to route the connection on the link is sent. The reserved priority bandwidth is used to route the connection when the connection has a reserved home path on the link. When the connection has a reserved home path not on the link, a determination is made as to whether a normal priority bandwidth on the link is available and whether the connection is unrestorable on another link. The reserved priority bandwidth is used to temporarily route the connection when normal priority bandwidth on the link is unavailable and the connection is unrestorable on another link.
摘要翻译：本发明的实施例提供了一种用于保留连接的归属路径资源并在包括预留优先级带宽的链路上恢复连接的方法和系统。分配指示保留的优先带宽可用的带宽通告，并发送请求路由链路上的连接的恢复请求。当连接在链路上具有保留的归属路径时，保留的优先带宽用于路由连接。当连接具有不在链路上的保留主路径时，确定链路上的正常优先带宽是否可用以及在另一链路上连接是否不可恢复。当链路上的正常优先级带宽不可用并且另一个链路上的连接不可恢复时，保留优先级带宽用于临时路由连接。

摘要： The present disclosure provides dynamic service provisioning by creating embedded Optical Transport Network (OTN) ports on the fly during mesh restoration or circuit provisioning. These dynamically provisioned ports are referred to herein as “fast paths” with all the management objects created in a “slow path” so that they do not interfere with mesh restoration performance. During network failures, these dynamically created objects are deleted via the “slow path” and a new mesh path supports “fast path” creation of these objects. This results in substantial increase in mesh performance and also provides enhancements for operators allowing a “Click and Go” model to provision circuits across a network. This also reduces routing scaling issue as the routing itself is against the OTU level and not against the embedded lines.
摘要翻译：本公开通过在网状网恢复或电路供应期间在运行中创建嵌入式光传输网络（OTN）端口来提供动态服务提供。这些动态配置的端口在这里被称为“快速路径”，其中所有管理对象在“慢路径”中创建，使得它们不干扰网格恢复性能。在网络故障期间，通过“慢路径”删除这些动态创建的对象，并且新的网格路径支持这些对象的“快速路径”创建。这导致网格性能的大幅提高，并且还为运营商提供增强功能，允许“Click and Go”模型在网络中配置电路。这也减少了路由规模问题，因为路由本身是针对OTU级别而不是针对嵌入式线路的。
