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。

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： A method and system for determining timers in a High Level Data Link Control (HDLC) Traffic Manager (HTM) state machine are disclosed. According to one aspect, the invention provides for determining a transit delay between two nodes by sending a first packet having a delay measurement byte to a second node that is on a link between the first node and the second node. A measured delay value is determined based on the delay between a time of sending the first packet to the second node and receiving a second packet from the second node. The timer values of the HTM state machine are set based on the measured delay value.

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： The present disclosure provides systems and methods for making latency measurements and using these measurements in routing in optical networks. In an exemplary embodiment, a method is defined whereby two nodes sharing a line automatically determine whether both nodes are capable of making a latency measurement and then which node will initiate and which node participates in making the latency measurement. In another exemplary embodiment, an on-demand latency measurement may be made between any two arbitrary nodes within a domain. Routing messages may be used to disseminate the latency of links via a signaling and routing protocol. Advantageously, the present invention provides measurement of latency and latency variation of customer circuits (i.e., SNCs) using an in-band, non-intrusive calculation with a high-degree of accuracy. Furthermore, the present invention may consider these calculations for circuit routing based on the latency and circuit acceptance based on maximum latency restrictions.
