Abstract: A self-calibration procedure for an optical transmitter is provided. During the self-calibration procedure, a phase bias of an optical modulator of the optical transmitter is set so that an in-phase path and a quadrature path of the optical modulator are in phase. Stimulus signals are supplied to the in-phase and quadrature paths of the optical modulator, over a frequency range. Detection, with a photodetector, is made of an optical output of the optical modulator at a plurality of frequency steps over the frequency range. A photodetector converts an optical output of the optical modulator to an electrical signal. First and second measurement values are generated from the electrical signal output from the photodetector. A frequency spectrum and/or time delay is computed from the first and second measurement values for each frequency step value over the frequency range.

Abstract: Techniques are presented herein to allow a tenant application in a cloud computing environment to automatically adjust storage infrastructure cache allocation according to performance needs and cost associated with use of the cache. Information is stored for a spot price of a cache of a storage infrastructure used for data storage in a cloud computing environment. A request is received to allocate additional cache for use by one or more applications associated with a first tenant running in the cloud computing environment. Information is sent to the one or more applications indicating a current spot price of the cache of the storage infrastructure. An instruction is received from the one or more applications to purchase the additional allocation of the cache based on the current spot price or based on a predetermined fixed price. An allocation request is sent to the storage infrastructure for additional allocation of the cache.

Abstract: One embodiment provides a system that facilitates routing updates outside of a routing protocol. During operation, the system receives, by an intermediate node, a first interest that indicates an originator name which is a routable name prefix for a sender of the first interest and is used by a content producing device in a subsequent interest. In response to not obtaining a matching entry in a forwarding information base (FIB) based on the originator name, the system adds a first entry to the FIB, wherein the first entry includes the originator name as a name for the first entry and further includes an arrival interface of the first interest as an outgoing interface for the first entry. In response to receiving the subsequent interest which has a name that includes the originator name, the system forwards the subsequent interest to the outgoing interface for the first entry.

The method still further include activating the backup wireless access link between the first routing device and the second routing device when it is determined that the status of the primary wired access link is indicative that the primary wired access link has failed.

Abstract: A system that automatically calibrates multiple speaker tracking systems with respect to one another based on detection of an active speaker at a collaboration endpoint is presented herein. The system collects a first data point set of an active speaker at the collaboration endpoint using at least a first camera and a first microphone array. The system then receives a plurality of second data point sets from one or more secondary speaker tracking systems located at the collaboration endpoint. Once enough data points have been collected, a reference coordinate system is determined using the first data point set and the one or more second data point sets. Finally, after a reference coordinate system has been determined, the system generates the locations of the one or more secondary speaker tracking systems with respect to the first speaker tracking system.

The cellular modem of the device may then send, using the capacitive reserve power, a cellular detach message into a cellular network, where the detach message has an indication that causes a receiving device to send a notification of the power failure to a configured endpoint device.

Abstract: Embodiments of the present disclosure provide method and apparatus for memory error correction. The method generally includes tracking information regarding detected errors with one or more memory locations of main memory which may be post-processed during a power-on cycle or component reset. For example, a processor may determine a probability of failure and failure type for the memory locations, based on which the processor may determine one or more memory locations to effectively swap with memory locations of a local memory (e.g., using failure bin groupings). In certain embodiments, due to a limited number of memory locations of main memory that may be swapped with local memory, each memory location may be continuously monitored in order to swap the memory locations of main memory that are highest priority candidates for error correction (e.g., determined based on a corresponding probability of failure and failure type, which may change over time).

Abstract: Presented herein are methods for advertising an IP prefix to address the connectivity problem in multi-chassis link aggregation scenario. A peer switch will advertise two VTEP addresses. It will use a physical IP (PIP) address as a next hop (NH) for a prefix route, while continuing to use a VIP for host IP and MAC route advertisement. A new virtual MAC is introduced and it is derived from the VIP as the router MAC associated with VIP. A switch is made to use a VIP for prefix advertisement when a device detects that the same prefix is reachable both locally and from its peer. This saves adjacency entries consumed in the remote VTEPs. These techniques fix the connectivity issue for prefix routes that is exposed with current EVPN, without requiring any additional adjacency resource consumption.

Abstract: In one embodiment, a device in an access network receives network condition data regarding the access network and requested flow characteristic data. The requested flow characteristic data is indicative of one or more flow characteristics requested by one or more subscribers for different periods of time. The device trains a machine learning-based classifier using the network condition data and the request flow characteristic data and receives a particular flow characteristic request from a particular subscriber node. The particular request indicates one or more requested flow characteristics for a specified time period. The device determines a probability of the access network being able to accommodate the particular flow characteristic request by classifying the particular flow characteristic request using the trained classifier. The device sends a flow characteristic response to the node of the particular subscriber node based on the determined probability.
