  • Patent number: 10805845
    Abstract: A system and method for managing a server in a packet data network. A transport protocol session is established between a client (20) and server (14_1) to transfer content from the server to the client in data packets. The transport protocol path is assigned an n-tuple identifier, whereupon the server transmits to the client data packets with the n-tuple identifier. The server additionally transmits declarative information as signaling packets with the n-tuple identifier, wherein the declarative information includes an identifier which is specific to the data being transmitted in the ongoing session. This allows other servers (14_2) to receive the signaling packets and detect the data that is being transmitted. If such another server then determines that it also has the same data and is better placed to serve that data to the client, it can offer to take over the session.

  • Patent number: 10785800
    Abstract: Systems and methods for dynamically selecting energy detection thresholds (EDTs) in radio nodes deploying listen before talk within a coordinated network to improve throughput on shared spectrum are disclosed. The radio nodes are configured to coordinate to deploy mechanisms to avoid or reduce interference issues, including collisions, with use of shared spectrum (e.g., unlicensed spectrum). One such mechanism is Listen Before Talk (LBT), and a radio node deploying LBT sets an EDT at which the radio node hears traffic from neighboring radio nodes on the shared spectrum. In an exemplary aspect, the EDT of radio nodes in the coordinated network of radio nodes can be dynamically selected and/or adjusted to improve throughput of the individual radio nodes and/or of the network of radio nodes as a whole.

  • Patent number: 10771394
    Abstract: Disclosed herein are systems and methods for multi-level classification of data traffic flows based on information in a first packet for a data traffic flow. In exemplary embodiments of the present disclosure, a key can be generated from intercepted DNS data to track data traffic flows by application names and source and destination IP addresses. Based on these keys, patterns can be discerned to infer data traffic information based on only the information in a first packet, such as source and destination IP address. The determined patterns can be used to predict classifications of future traffic flows with similar key information. In this way, data traffic flows can be classified and steered in a network based on limited information available in a first packet.

Specifically, a terminal acquires first interference information indicating the strength of inter-RU interference after analog interference cancellation, and second interference information indicating the strength of inter-RU interference before analog interference cancellation. The terminal determines whether space division duplex communication can be performed between RUs, by comparing the interference strength indicated by the first interference information with a first threshold. The terminal determines whether inter-RU interference needs to be periodically measured, by comparing the interference strength indicated by the second interference information with a second threshold.

  • Patent number: 10735337
    Abstract: A network traffic manager receives, from an ingress port, a cell of a packet destined for an egress port. Upon determining that a number of cells of the packet stored in a buffer queue meets a threshold value, the manager checks whether the ingress port has been assigned a token corresponding to the queue. Upon determining that the ingress port has been assigned the token, the manager determines whether other cells of the packet are stored in the buffer, in response to which the manager stores the received cell in the buffer, and stores linking information for the received cell in a receive context for the packet. When all cells of the packet have been received, the manager copies linking information for the packet cells from the receive context to the buffer queue or a copy generator queue, and releases the token from the ingress port.
