Abstract: A microphone array includes one or more front-facing microphones disposed on a front surface of the collaboration endpoint and a plurality of secondary microphones disposed on a second surface of the collaboration endpoint. The sound signals received at each of the one or more front-facing microphones and the plurality of secondary microphones are converted into microphone signals. When the sound signals have a frequency below a threshold frequency, an output signal is generated from microphone signals generated by the one or more front-facing microphones and the plurality of secondary microphones. When the sound signals have a frequency at or above a threshold frequency, an output signal is generated from microphone signals generated by only the one or more front-facing microphones.

Abstract: A first manifest request may be received and, in response, a first manifest may be requested. Next, at least one interstitial content insertion source may be queried based on the first manifest and, in response to querying the interstitial content insertion source, interstitial content details may be retrieved from the at least one interstitial content insertion source. Then it may be determined that a version of interstitial content corresponding to the interstitial content details does not exist in a service provider back end at same bitrates as content corresponding to the first manifest. Next, local ingest and encoding of the interstitial content to the service provider back end may then be triggered in response to determining that the version of interstitial content corresponding to the interstitial content details does not exist in the service provider back end at the same bitrates as the content corresponding to the first manifest.

Abstract: In one illustrative example, a router may be configured to provide a plurality of virtual private network (VPN) instances for a plurality of VPNs associated with a plurality of IDs. Each VPN instance may comprise a forwarding table instance for storing a plurality of host-to-router mappings for the VPN. The router may be further configured to provide a virtual VPN instance for a virtual VPN associated with an ID of a remote extranet VPN. The virtual VPN instance may comprise a map-cache for storing a host-to-router mapping for the remote extranet VPN. The virtual VPN instance has no corresponding forwarding table instance for user plane traffic associated with the remote extranet VPN, but rather serves as part of a control plane interface for control signaling associated with the remote extranet VPN. Accordingly, the router may provide multiple updates to host-to-router mappings in forwarding table instances of the VPNs in accordance with a change in the host-to-router mapping in the virtual VPN instance.

Abstract: In one embodiment, a device receives health status data indicative of a health status of a data source in a network that provides collected telemetry data from the network for analysis by a machine learning-based network analyzer. The device maintains a performance model for the data source that models the health of the data source.

The switch has a central processing unit (CPU), the CPU comprising a reload handler and an application-specific integrated circuit (ASIC), the ASIC comprising ASIC forwarding logic. The ASIC is instructed, by the reload handler, to store an ASIC database, the ASIC database for storing the ASIC forwarding logic. The reload handler maintains a physical layer (PHY) state of the switch. Use of spanning tree protocol (STP) and Transmission Control Protocol (TCP) keepalive is disabled in the switch. A state of stack hardware is retained in switch memory. New ports of the switch are prevented from becoming active, and the ASIC forwarding logic is, in response to receiving the instruction, stored in the ASIC database. Related systems, apparatuses, and methods are also described.

Abstract: Embodiments herein describe a photonic chip which includes a coupling interface for evanescently coupling the chip to a waveguide on an external substrate. In one embodiment, the photonic chip includes a tapered waveguide that aligns with a tapered waveguide on the external substrate. The respective tapers of the two waveguides are inverted such that as the width of the waveguide in the photonic chip decreases, the width of the waveguide on the external substrate increases. In one embodiment, these two waveguides form an adiabatic structure where the optical signal transfers between the waveguides with minimal or no coupling of the optical signal to other non-intended modes. Using the two waveguides, optical signals can be transmitted between the photonic chip and the external substrate.

Abstract: A controller of a collaboration endpoint generates a primary audio signal for an ultrasonic source audio signal produced by a source audio speaker, a reference audio signal for the ultrasonic source audio signal, and, based on the reference audio signal, a predicted signal that is predictive of the primary audio signal. The controller produces a prediction error of the predicted signal by comparing the primary audio signal with the predicted signal and determines whether the prediction error is indicative of a motion of one or more persons near the collaboration endpoint.
