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： Mechanisms, in a data processing system comprising an input/output subsystem implementing an industry standard optical bus, for handling a failure of an optical channel in an optical bus are provided. The mechanisms detect, by failure detection logic of the input/output (I/O) subsystem, failure of an optical channel of the optical bus. The mechanisms send, by a controller of the I/O subsystem, a control signal to channel routing logic of the I/O subsystem to control a routing of data signals between active bus lanes of the data processing system and optical channels of the optical bus in response to detecting the failure of the optical channel. The mechanisms control, by the channel routing logic, routing of data signals between the active bus lanes and the optical channels so as to remove the failed optical channel from further use and use a spare optical channel instead of the failed optical channel.

摘要： The embodiments disclosed herein provide fast recovery of a network signal path by, in the event of a failure or unacceptable degradation in a signal in the original network path, diverting the optical signal passing through the network to a preselected bypass optical path which is maintained in a warm or operational state. The optical elements on the bypass optical path are available network resources which may, during part or all of the time the bypass path is designated for a node in the primary optical path, be in use to transmit other optical signals in the network. By maintaining the resources in the designated bypass path in a warm or operating state, fast rerouting and recovery of an interrupted signal is possible.

摘要： In one or more embodiments, a cellular signal is received and directed to a path bypassing active amplifier circuitry. This may be in response to the active amplifier circuitry being non-operational (e.g., in a fault state) or detecting that an RF environment does not necessitate amplification. Bypassing the active amplifier circuitry may enable transmission of a non-amplified cellular signal when active circuitry is in a fault state or while traveling through areas of strong cellular service (e.g., proximate a cell tower).

摘要： A primary optical path in an optical network is established between first and second edge nodes of the optical network for communication between the first edge node and a primary customer network site coupled to the second edge node. A backup optical path through the optical network from the first edge node to a third edge node of the optical network other than the second edge node is determined for communication between the first edge node and a backup customer network site coupled to the third edge node of the optical network. The backup customer network site is designated to back up the primary customer network site. Communications are forwarded on the primary optical path from the first edge node toward the primary customer network site via the second edge node. Upon detection of a degradation or failure of the primary customer network site, communications are forwarded on the backup optical path from the first edge node toward the backup customer network site via the third edge node.

摘要： Embodiments of the present invention disclose a troubleshooting method. The method includes: determining, by an aggregation node when a link fault or a device fault occurs on an OLT side, an active logical port used by the active OLT to forward a data packet; searching, by the aggregation node, a locally stored logical port mapping table according to the active logical port to obtain a standby logical port corresponding to the active logical port, where the standby logical port supports a same user service as the active logical port; and triggering, by the aggregation node, the standby OLT to enable the standby logical port to receive a data packet that is sent by the standby OLT through the standby logical port. The implementation of the present invention can provide utmost compatibility with the live network and enable a communication link to recover from a fault quickly.
