A wireless mesh network is configured to implement a latency-sensitive communication protocol in order to facilitate data communications between devices coupled to that network and configured to communicate with one another based on that protocol. Specifically, a node within the wireless mesh network receives a continuous stream of data that includes an N-bit sequence from an upstream device coupled to the wireless mesh network. The node transmits the N-bit sequence to a downstream node within the wireless mesh network. The downstream node re-creates the continuous stream of bits based on the received N-bit sequence, and then transmits the re-created continuous stream of bits to another device coupled to the wireless mesh network. By operating in conjunction with one another, the nodes within the wireless mesh network facilitate communication between the devices coupled to wireless mesh network according to the latency-sensitive communication protocol.

Various example embodiments for supporting communications for data storage are presented herein. Various example embodiments for supporting communications for data storage may be configured to support communications between a host and a storage element for supporting storage of data in the storage element by the host. Various example embodiments for supporting communications between a host and a storage element may be configured to support communications between a host and a controller of the storage element. Various example embodiments for supporting communications between a host and a controller of a storage element may be configured to support, using a single transport layer connection, communications of multiple queue pairs supporting communications between the host and the controller of the storage element, where each of the queue pairs includes a queue on the host and a queue on the controller of the storage element.

This application discloses a communications method and related communications apparatus and system. The method includes recovering, by a first node, when detecting that a first packet is lost, the first packet according to a local recovery mechanism. The first packet is a packet obtained based on a packet sent by at least one first terminal to at least one second terminal, and the first node is a node on a network path between each first terminal and a second terminal communicating with the first terminal. The method further includes adding a first identification information related to local recovery, and sending the first packet. This application can reduce a transmission delay and improve transmission efficiency.

A queue management method, system, and recording medium include Selective Acknowledgments (SACK) examining to examine SACK blocks of a forwarder to selectively drop packets in a forward flow queue based on a reverse flow queue and MultiPath Transmission Control Protocol (MPTCP) examining configured to perform a first examining to examine multipath headers to recognize MPTCP flows based on a comparison between two subflows being a part of a same superflow and a second examining to examine the reverse flow queue to determine if redundant data has been sent based on a result of the first examining, a packet in the forward flow queue from a prior transmission being dropped from the forward flow queue sent from the forwarder to a receiver if a metadata of the packet does not match a metadata of an acknowledged packet in the reverse flow queue.

A method of reducing the bandwidth usage of a network comprises intercepting traffic between a TCP server and a TCP client using TCP protocols that use client acknowledgements; identifying client acknowledgements from the TCP protocols; identifying the sequence number of a last received client acknowledgements from the intercepted traffic; identifying the sequence number of a last sent client acknowledgement from the intercepted traffic; calculating an unacknowledged byte value based on the difference between the last received client acknowledgement sequence number and the last sent client acknowledgement sequence number; comparing the calculated unacknowledged byte value with a predetermined threshold value, to determine whether the calculated unacknowledged byte value is at least as great as the predetermined threshold value; and transmitting the identified client acknowledgements into the network when the compared unacknowledged byte value is at least as great as the predetermined threshold value.

A method for preserving a transmission rate of second data transmitted by a first terminal destined for a second terminal attached to at least one access device in a communications network. A communications network node capable of routing the second data identifies an inability of the at least one access device to send first data received from the first terminal to the second terminal, processes the first data received from the first terminal during the identified period of inability of the at least one access device, and transmits to the first terminal a notification indicating that the first stored data is not subject to congestion.

A system includes a server; a plurality of wireless networks coupled to the server; and one or more mobile devices coupled to the wireless networks with intermittent access to the wireless networks, the plurality of wireless networks providing data communication between client and server applications over multiple available connections.

A computing device may include a memory and a processor cooperating with the memory to access a session hosted by a remote computing device, and classify a group of data packets into first and second data packets. The first data packets may define reference points for reassembly of the group of data packets with the second data packets at their original positions in the group of data packets. The processor may further send the first and second data packets to the remote computing device via different channels with different rates of packet loss to enable reconstruction of the group of data packets at another device.
