Abstract: A waveguide coupler has a compression region and an expansion region for coupling light between a silicon waveguide and an optical fiber. The compression region receives light from the silicon waveguide and compresses an optical mode of the light. Light is transmitted from the compression region to an expansion region. The expansion region expands the light to have a larger cross section. Light is then transmitted to the optical fiber.

Abstract: Embodiments include methods and apparatuses for providing at least one signaling indication of a super-channel by a power controller in a Wavelength Division Multiplexing (WDM) system. The power controller may receive a service provisioning and a lock state from a network management entity. The power controller may receive, from an optical fabric unit, a fabric state that indicates whether a pass-band of the super-channel is provisioned. The power controller may receive the power level of the super-channel from a power monitoring unit. Based on the power level and attenuation level of the super-channel, the power controller may determine a ramp state that indicates whether the power level reached to a predetermined power. The power controller may determine an alarm state based on the power level. The power controller may determine the signaling indication based on the service provisioning, lock, fabric, ramp, and alarm states.

Abstract: Herein disclosed are systems, methods, and apparatus for controlling data usage statistics in network-connected devices. The ‘stats’ collection can be suppressed during minimum window periods, thereby reducing CPU and resources usage needed to processes the stats collection. Further, the minimum window can be a function of a link speed of the communication channel as well as a data usage proximity to a data usage warning limit. Further, stats collection can be triggered by expiration of a timer or data usage that meets a buffer threshold, where both the timer and threshold are selected based on the communication channel link speed, and buffer threshold is further a function of the data usage proximity to the warning limit.

Abstract: The present invention provides for a consolidated interface for flexible and customizable code deployment. Specifically, a centralized interface for management and automation of all phases of code deployment; including, but not limited to, code validation, validation approval, code deployment and data reporting/auditing. Code is automatically validated regardless of which standards or regulations apply to the programs/entities, platforms and/or applications associated with a code deployment. In addition, any known, or future known, code deployment tool and/or reporting/auditing tool may be used to conduct the deployment/migration and/or provide requisite reporting. Additionally, the systems herein disclosed are capable of integrating with any new/future platform, new/future software applications/packages and/or updates/revisions to applications/software packages without having to modify or reconfigure the disclosed system.

Abstract: Embodiments herein include methods and apparatuses for providing optical channel protection by a switching controller in an optical networking system. The switching controller may receive, from a light module, a digital fault status message that indicates whether a digital frame demodulated from an optical signal include a fault. The switching controller may receive from an Optical Supervisory Channel (OSC) module, an Optical Layer Defect Propagation (OLDP) status message that indicates an OSC status of the optical signal on a current optical path. The switching controller may receive, from an Optical Add Drop Multiplexer (OADM) module, an optical power status message that indicates a measured power level of the optical signal on the optical path. Based on at least one of the OLDP status, the optical power status, or the digital fault status message, the switching controller may determine the optical path as a working path or a protecting path.

Abstract: An intermediary can securely migrate a security credential between systems despite different underlying encoding technologies used for authentication by the system. This intermediary can also securely migrate an identity between different authentication technologies. A secure login interface program code that is digitally signed by the intermediary is provided in advance to devices that will source authentication requests. The interface program code is at least secure because it has been digitally signed by the intermediary. An instance of the secure interface program code directs authentication requests entered into the interface instance to the intermediary, which is at least identified by the digital signature. After a successful authentication by a destination system identified by the authentication request, the intermediary can migrate the authenticated security credential to a migration target.

Abstract: The present invention and its embodiments are made to provide for dynamic hitless resizing in optical transport network without any identification of matching time slots by the Network Management System (NMS) or any control plane signaling including Generalised Multi Protocol Label Switching (GMPLS). An aspect of the invention provides for a method of hitless ODUflex connection resizing in an optical transport network by incrementing or decrementing the ODUflex connection between the nodes, based on an indication command given to a source node for bandwidth increase or decrease, by identifying and matching at least one time slot through Link Connection Resizing (LCR) protocol message exchanges. Another aspect of the invention provides for a method of hitless ODUflex connection resizing in an optical transport network by decrementing the matching time slot used for the incrementing operation, in case of unsuccessful incrementing operation between nodes.

Abstract: This disclosure describes systems, methods, and apparatus for reducing power consumption and improving performance on a computing device. A method includes scheduling, with a driver on the computing device, one or more activity times that indicate when the driver will be active and storing the one or more activity times that indicate when the driver will be active. When a request to suspend a system of the computing device is received, the stored activity times are accessed to identify when the driver will be active, and a determination is made whether any of the one or more activity times is scheduled to occur within a suspend time window. If the driver will not be active during the suspend time window, suspension of the system is initiated.
