  • Publication number: 20220256114
    Abstract: A new real-time video communication device improves the clarity of shared screen by automatically adjusting the key frame's quantization parameter values. The adjustment depends on the underlying network's connection condition. When the connection bandwidth deteriorates, the key frame's quantization parameter value is further decreased on the value output from a standard H.264 encoder to derive a desirable quantization parameter value and thus achieve a desirable user experience of the shared screen. Moreover, the new real-time video communication device adjusts the frame rate of the shared screen based on the present quantization parameter value to achieve a more desirable user experience of the screen sharing.

  • Publication number: 20220247696
    Abstract: Examples described herein relate to a reliable transport protocol for packet transmission using an Address Family of an eXpress Data Path (AF_XDP) queue framework, wherein the AF_XDP queue framework is to provide a queue for received packet receipt acknowledgements (ACKs). In some examples, an AF_XDP socket is to connect a service with a driver for the network device, one or more queues are associated with the AF_XDP socket, and at least one of the one or more queues comprises a waiting queue for received packet receipt ACKs. In some examples, at least one of the one or more queues is to identify one or more packets for which ACKs have been received. In some examples, the network device is to re-transmit a packet identified by a descriptor in the waiting queue based on non-receipt of an ACK associated with the packet from a receiver.

  • Patent number: 11405238
    Abstract: A controlling device is disclosed for Ethernet virtual private network (EVPN). According to an embodiment, the controlling device determines a first provider (P) device which is to handle broadcast, unknown unicast or multicast (BUM) traffic from a first provider edge (PE) device in an EVPN instance, on behalf of remaining PE devices in the same EVPN instance. The controlling device performs route reflection from the remaining PE devices to the first PE device such that the first PE device knows that BUM traffic needs to be forwarded to the first P device. The controlling device configures the first P device such that upon receipt of BUM traffic from the first PE device, the first P device can forward the BUM traffic to the remaining PE devices.

  • Patent number: 11326884
    Abstract: A disk resonator is pumped by counterpropagating pump signals to produce corresponding counterpropagating Brillouin laser signals. The pump laser optical frequencies are separated by a frequency offset ??P but excite the same nominal resonator optical mode; the Brillouin laser optical frequencies are separated by a beat frequency ??L with 0<??L<??P. A photodetector receives the Brillouin laser signals and produces an electrical signal at the beat frequency ??L. The frequency offset ??P can be large so enough to prevent locking of the Brillouin laser signals onto a common Brillouin laser frequency. A signal processing system derives from the beat frequency ??L an estimated angular velocity component of the disk optical resonator about an axis substantially perpendicular to the disk optical resonator.
