US 2021/0344603 A1 · MANAGING TRANSMISSION CONTROL PROTOCOL (TCP) TRAFFIC

Abstract

A terrestrial terminal enables communications, over a network connection, between a local host of one or more connected local hosts and a remote host. The terrestrial terminal is configured to perform operations comprising: receiving, from the remote host, a network packet for the local host; obtaining, from the network packet, an included TCP segment; determining, from the TCP segment, a receive window size advertised by the remote host; computing, using one or more characteristics of the network connection, a target receive window size; comparing the target receive window size with the advertised receive window size; and in response to determining that the target receive window size is different from the advertised receive window size: modifying the TCP segment by replacing the advertised receive window size with the target receive window size, and forwarding the network packet with the modified TCP segment to the local host.

Claims20

Dependent claims

A system comprising:

a terrestrial terminal connecting a local host with a remote host over a network connection, wherein the terrestrial terminal is configured to perform operations comprising:
obtaining a receive window size advertised by the remote host for a Transmission Control Protocol (TCP) connection between the local host and the remote host;
determining that the advertised receive window size is different from a target receive window size for the network connection;
in response to the determining, modifying TCP segments in one or more network packets received from the remote host by replacing the advertised receive window size with the target receive window size in the TCP segments;
and
forwarding the one or more network packets with respective modified TCP segments to the local host.

3 more elements

A method performed by a terrestrial terminal connecting a local host with a remote host over a network connection, the method comprising:

obtaining a receive window size advertised by the remote host for a Transmission Control Protocol (TCP) connection between the local host and the remote host;
determining that the advertised receive window size is different from a target receive window size for the network connection;
in response to the determining, modifying TCP segments in one or more network packets received from the remote host by replacing the advertised receive window size with the target receive window size in the TCP segments;
and
forwarding the one or more network packets with respective modified TCP segments to the local host.

2 more elements

One or more non-transitory machine-readable media storing instructions that, when executed, are configured to cause one or more processors to perform operations comprising:

obtaining, at a terrestrial terminal connecting a local host with a remote host over a network connection, a receive window size advertised by the remote host for a Transmission Control Protocol (TCP) connection between the local host and the remote host;
determining that the advertised receive window size is different from a target receive window size for the network connection;
in response to the determining, modifying TCP segments in one or more network packets received from the remote host by replacing the advertised receive window size with the target receive window size in the TCP segments;
and
forwarding the one or more network packets with respective modified TCP segments to the local host.
