Abstract

A computer system splits data to be transmitted into a plurality of reliable connections which are multiplexed through a smaller number of unacknowledged connections, such as connections that do not require acknowledgment and which may be VPN tunnels. A receiver then demultiplexes data received to obtain data flows over the reliable connections and transmits separate acknowledgements for each reliable connection. The computer system demultiplexes the acknowledgments and provides them to the corresponding reliable connections, which then retransmit any unacknowledged data. Delivery controllers executing on the computer system may be coupled to corresponding controllers executing on the receiver, with traffic between the delivery controllers (payload and acknowledgments) being multiplexed over one or more unacknowledged connections. In some embodiments, acknowledgments may be transmitted over a connection that is not multiplexed over the unacknowledged connections.

Claims23

Dependent claims

A method comprising:

providing, by a computer system, one or more first network connections to a remote computing device;
receiving, by the computer system, an instruction to transmit payload data to the remote computing device;
and
in response to the instruction—
(i) dividing, by the computer system, the payload data into data portions;
(ii) transmitting, by the computer system, the data portions over a second number of second network connections;
(iii) multiplexing, by the computer system, the data portions transmitted over the second network connections through a first number of one or more first network connections, the first number being smaller than the second number;
(iv) receiving, by the computer system, one or more acknowledgements corresponding to at least parts of one or more of the data portions, each acknowledgment of the one or more acknowledgments referencing a second network connection of the second network connections;
(v) demultiplexing, by the computer system, each acknowledgment of the one or more acknowledgments onto the second network connection of the second network connections referenced by the each acknowledgment;
(vi) determining, by the computer system, that acknowledgment was not received for at least part of at least one data portion of the data portions by at least one second network connection of the second network connections over which the at least one data portion was transmitted;
and
(vii) in response to determining that acknowledgment was not received for the at least one data portion, retransmitting the at least the part of the at least one data portion over the at least one second network connection.

A computer system comprising one or more computing devices, the one or more computing devices each comprising one or more processing devices and one or more memory devices operably coupled to the one or more processing devices, the one or more memory devices of the one or more computing devices storing executable code effective to cause the one or more processing devices of the one or more computing devices to

establish a first number of one or more first network connections terminating at a remote computing device;
establish a second number of second network connections, the first number being smaller than the second number;
transmit payload data to the remote computing device by—
(i) dividing the payload data into data portions;
(ii) transmitting the data portions over different connections of the second network connections;
and
(iii) multiplexing the data portions transmitted over the second network connections through the one or more first network connections;
and
verifying transmission of payload data to the remote computing device by—
(iv) receiving acknowledgments over the first network connections;
(v) demultiplexing each acknowledgment onto a network connection of the second network connections referenced by the each acknowledgment;
and
(vi) if acknowledgment of receipt of at least a part of one or more of the data portions is not received on one or more second network connections of the one or more second network connections, retransmitting the at least the part of the one or more of the data portions over the one or more second network connections.
