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: 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: Systems, methods, and devices for adding an alien or native wavelength optical signal to a fiber optic line. A portion of a spectrum of the fiber optic line corresponding to the optical signal is blocked with a wavelength selective switch (WSS). The portion of the spectrum is gradually unblocked until a power of the optical signal measured after the WSS is equal to a predetermined level. If the power and characteristics of the optical signal after the WSS satisfy one or more criteria, the portion of the spectrum is further unblocked until the power of the optical signal measured at the output is equal to an operational level.

Abstract: This description describes a system for identifying individuals within a digital file. The system accesses a digital file describing the movement of unidentified individuals and detects a face for an unidentified individual at a plurality of locations in the video. The system divides the digital file into a set of segments and detects a face of an unidentified individual by applying a detection algorithm to each segment. For each detected face, the system applies a recognition algorithm to extract feature vectors representative of the identity of the detected faces which are stored in computer memory. The system applies a recognition algorithm to query the extracted feature vectors for target individuals by matching unidentified individuals to target individuals, determining a confidence level describing the likelihood that the match is correct, and generating a report to be presented to a user of the system.

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: Systems and methods are described in which circuitry of a first controller of a first node receives a first signal indicating an optical loss of signal within the first path. Circuitry of a second controller of the first node on the first path within a transport network generates a second signal indicating a failure within the first path. The first controller accessing a network topology database determines that restoration of the first path would be ineffective due to there being no alternate path, and signals a second node downstream in the first path with the second signal indicating the failure within the first path, and a third signal indicating that restoration of the first path would be ineffective due to there being no alternate path.

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: A secure identity framework has been designed that leverages a host device as a data collection point for four properties of a digital identity profile anchored to the collection point device, and uses the digital identity profile for multi-factor authentication. A public key infrastructure key exchange is conducted for secure identity framework members corresponding to collection and access of data of the digital identity profile. Subsequently, each application participating in the secure identity framework (“participant application”) acts as a certifying authority in additional, distinct PKI key exchanges. Based on the key exchanges, the secure identity framework locally generates application specific token sets based on the digital identity profile for authentication and authorization. The secure identity framework secures exchange of data among hardware and software components of the device with secured application programming interfaces (APIs).
