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： 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： A method and system for determining timers in an 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. The method also includes receiving a second packet with the delay measurement byte from the second node. The delay measurement byte sent by the second node is adjusted by the second node to indicate its receipt by the second node. A measured delay value is determined. The measured delay value is the delay between a time of sending the first packet to the second node and receiving the second packet from the second node. The measured delay value is determined by the hardware of the first node. Upon determining the measured delay value, timer values of the HTM state machine are set based on the measured delay value.

摘要： The present disclosure provides systems and methods for mesh restoration based on Associated Hop Designated Transit Lists (DTLs). The Associated Hop DTLs are calculated through a global restoration calculation (GRC) algorithm that can be run by a central controller in an offline manner. The restoration paths calculated by the GRC algorithm can then be pushed down to the originating nodes for each connection to utilize at the time of a given failure scenario. This GRC algorithm can be performed for each possible bundle failure in the network, where a bundle failure is determined by the set of all links which may fail together due to common shared risk, such as a common conduit or DWDM fiber. The globally calculated, contention free, restoration paths are then pushed down to each node in the network.
