System and method of a graceful reboot of a network controller

Abstract: A method and apparatus to bring up a network controller in a network of multiple network elements is described. In an exemplary embodiment, the network controller receives an indication that the network controller is booting up. The network controller is coupled to a plurality of network elements in a network, where the network controller maintains a controller database that supports a network-wide service used by the plurality of network elements. The network controller further receives state information from the plurality of network elements. In addition, the network controller builds the controller database from the state information. Furthermore, the network controller sends updates from the controller database to each of the plurality of network elements, where each of the plurality of network elements incorporates these updates into a respective network element database and the network element database is used to perform the network-wide service.

P-Tracer: Proximity Detection for Contact Tracing

Abstract: COVID-19 pandemic has impacted millions of people worldwide. To tackle the spread of disease, governments all over the world had to impose sudden lockdowns with strict restrictions and has resulted in stressing most of the enterprises on the financial fronts. As the governments all over the world are now relaxing the restrictions, businesses are re-opening gradually and employees are returning back to work. There is huge responsibility on the enterprises to stay vigilant when an employee tests positive for COVID-19. To target the issue, we have come up with a contact tracing solution, P-Tracer application which uses users wifi association data from Arista Networks’ Cloud-Vision Wifi. This paper shortly presents the P-Tracer application working principle. We claim that the application will be useful in tracing the users association journey and detection of new hot zones and possible new cases.

Wide bandwidth bidirectional clock synchronization circuit

Abstract: A bidirectional clock synchronization circuit is provided. The circuit includes a bidirectional port having an input/output terminal and a transceiver, having a first interface with a unidirectional input and a unidirectional output, and a second interface with a bidirectional input/output coupled to the input/output terminal of the bidirectional port. The circuit includes a phase locked loop (PLL), having an output coupled to the unidirectional input of the transceiver, and having an input coupled to the unidirectional output of the transceiver, the phase locked loop selectable as to frequency range for the input or the output of the phase locked loop.

Method and network device for overlay tunnel termination and mirroring spanning datacenters

Abstract: A method and network device for overlay tunnel termination and mirroring spanning datacenters. Specifically, the method and network device disclosed herein entail the traversal of mirrored network traffic from datacenters lacking traffic analysis tools to other datacenters including the sought after traffic analysis tools. Further, the aforementioned traversal of mirrored network traffic may utilize virtual network layer overlay domain tunnels.

Fan with EMI absorbent blades

Abstract: An air-moving device with electromagnetic interference (EMI) reduction is provided. The air moving device, which may be embodied as a fan, includes a motor, one or more blades coupled to the motor, and each of the one or more blades comprising EMI absorbent material.
