  • Patent number: 9019992
    Abstract: A method for controlling error resilience in network communication is described. The method includes: determining, by a receiver-side controller, a packet gap representing a packet loss of a packet being communicated over a network; projecting, by the receiver-side controller, a retransmission time-out for at least one missing packet of the packet loss; issuing, by the receiver-side controller, a retransmission request for the at least one missing packet; if the packet gap is not filled within a first time period of the retransmission time-out, then issuing, by the receiver-side controller, at least one synchronization frame request; and selecting, by a sender-side controller, to respond to at least one of either of the retransmission request or the at least one synchronization frame request and neither of the retransmission request nor the at least one synchronization frame request.

  • Patent number: 9014034
    Abstract: A network access device for network traffic analysis of a plurality of client devices in a local area network (LAN) maintains a hierarchical key combination traffic analysis (HKCTA) table for each of the client devices of the LAN (LAN devices) to store network traffic statistics of each LAN device, wherein the HKCTA includes entries identified by keys, each key being formed based on a combination of zero or more packet attributes of packets or flow attributes of a network flow associated with the packets (packet/flow attributes) exchanged by the LAN device. Each key represents one of hierarchical levels of a hierarchy of the entries. Each level of the hierarchy includes all packet/flow attributes of its parent hierarchical level plus at least one additional packet/flow attribute that is not present in its parent hierarchical level.

  • Patent number: 8995269
    Abstract: A server stores data to be transmitted in a first S queue, reads the data stored in the first S queue, and transmits it. If congestion is detected, from among data to be transmitted after the congestion is detected, the server stores, in a second S queue, data other than data for the destination for which the congestion is detected. If congestion is detected, from among data to be transmitted after the congestion is detected, the server stores, in a D queue, data for a destination for which the congestion is detected. After the data is stored in the first S queue, the server reads data stored in the second S queue and transmits it. After the data is stored in the first S queue, the server reads the data stored in the D queue, controls a bandwidth thereof, and transmits the data in the D queue.
