摘要： Systems and methods for the implementation of a remote test access feature using virtual connection points and sub-network connections by the merge-and-split of flexible permanent virtual circuits. A sub-network connection is created between a remote test set and a connection termination point of a circuit of interest through the provision of two endpoints of interest. Subsequently, monitoring and management capabilities are established and operation, administration, and maintenance functions are performed at a centralized location using a network management system. The remote tap used may employ any protection scheme and mesh restore, as necessary, either manually or automatically, in the event of signal degrade or failure scenarios. The endpoint of the remote tap may be selectively changed, and the remote tap re-groomed for a different circuit of interest via a simple point-and-click.

摘要： The present invention provides systems and methods for programming connections through a multi-stage switch fabric. The present invention utilizes load-balancing, blocking recovery, background rebalancing, and rollback algorithms to select and manage connection balance on center stage switches in the multi-stage switch fabric for new and modified connections. The load-balancing algorithm attempts to spread the multi-connection slices across center stage switches as evenly as possible, to increase the probability that future multi-connection slices can be added without needing to rearrange existing slices. Advantageously, the present invention is efficient by making the best possible local decision for one multi-connection slice at a time, without considering other multi-connection slices that may also need center switch assignments. Additionally blocking recovery, rollback and background rebalancing features are also supported.

摘要： The present invention provides systems and methods for the implementation of a remote test access feature using virtual connection points and sub-network connections by the merge-and-split of flexible permanent virtual circuits. The remote test access feature of the present invention represents a highly flexible and fully automated technique that utilizes and exploits a network cloud. A sub-network connection is created between a remote test set and a connection termination point of a circuit of interest through the provision of two endpoints of interest. Subsequently, monitoring and management capabilities are established and operation, administration, and maintenance functions are performed at a centralized location using a network management system. The remote tap used may employ any protection scheme and mesh restore, as necessary, either manually or automatically, in the event of signal degrade or failure scenarios. The endpoint of the remote tap may be selectively changed, and the remote tap re-groomed for a different circuit of interest via a simple point-and-click. Thus, problems anywhere in the transport network may be tracked down.

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： A method, system and egress switching node for maintaining a network connection in an optical network reduces the number of spans needed for reestablishing a network connection. The invention learns which channels are used by the network connection and propagates such channel assignment data to the switching nodes for storage therein. When a span failure occurs, a notification is sent to the switching nodes identifying which span has failed. The switch nodes use the notification and channel assignment data to perform protection switching such that the rerouted network connection selects the channel that was used by the network connection on the failed span. Likewise, the egress switching node uses the selected channel to drop the network connection from the protecting fibers. This enables a network connection to travel a shorter distance after a protection switch.
摘要翻译：用于维护光网络中的网络连接的方法，系统和出口交换节点减少了重新建立网络连接所需的跨度数量。本发明学习网络连接使用哪些信道，并将这种信道分配数据传播到交换节点以便存储在其中。发生跨度故障时，会向交换节点发送一个通知，以确定哪个跨度发生故障。交换机节点使用通知和信道分配数据进行保护倒换，使得重新路由的网络连接选择故障跨度上由网络连接使用的信道。类似地，出口交换节点使用所选择的信道从保护光纤中丢弃网络连接。这使得网络连接能够在保护开关之后行驶较短的距离。
