    摘要： An object of the present disclosure is to provide a communication path switching method for improving a throughput of TCP communication at the time of switching a communication path between a first communication path that is at least one of a low latency or high speed and a second communication path that is at least one of a high latency or low speed.
    The communication path switching method according to the present disclosure is a communication path switching method for switching a communication path to a first communication path or a second communication path by using operation of a TCP accelerator in a communication path switching system including a terminal that performs TCP communication by switching a communication path between the first communication path that is at least one of a low latency or high speed and the second communication path that is at least one of a high latency or low speed, the communication path switching method including: receiving data from the terminal; and when the data is first received after the communication path is switched from the first communication path to the second communication path, transmitting again to the terminal, an acknowledgement signal transmitted last before the communication path is switched.

    摘要： When a control signal transmitted from a session management functional unit receiving a connection instruction (for example, Attach or the like) of a terminal is received, a policy management functional unit of a network apparatus notifies a LAN located between a core network and the Internet of a policy for the terminal. Specifically, the policy management functional unit notifies the LAN of the policy via a TCP-based interface or an SCTP-based interface. The policy management functional unit receives the control signal via the TCP-based interface or the SCTP-based interface.

    摘要： Method, apparatus and system may control chronological sequencing of data items received from a plurality of client computing devices, according to times of completion of transmission respectively from the client computing devices and distributing the data items according to the chronological sequencing to one or more destination computing devices with minimal latency. In an exemplary implementation, trade orders from participant computing devices may be distributed by an electronic trading platform with minimal latency to exchange gateways, based on time of transmission of the trade orders to the platform instead of time of receipt of the trade orders by the platform, thereby avoiding unfairness to those participants whose computing devices are located at greater distances from the platform than other computing devices respectively of other participants.

    摘要： A method for estimation of performance characteristics for transport control protocol includes sparsely sampling, at a middlebox, a plurality of packets from a transport control protocol (TCP) connection between a source endpoint and a destination endpoint through the middlebox. For each packet of the sampled plurality of packets, the method includes generating a time stamp when the packet is sampled and recording a sequence number and an acknowledgment number for the respective packet. The acknowledgment number is recorded when the acknowledgment number exists for the respective packet. The method also includes generating an estimated performance characteristic for the TCP connection between the source endpoint and the destination endpoint through the middlebox over the period of time based on at least two of a respective time stamp, a respective sequence number, or a respective acknowledgment number from one or more of the sampled plurality of packets.

    摘要： Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.
