US 9,794,758 B2 · Increasing reliable data throughput in a wireless network

Abstract

Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.

Dependent claims

An access point device in a wireless local area network comprising:

a transmitter for transmitting a first data packet, according to a higher layer protocol, received from a source network node^ to a destination network node in the wireless local area network;
and
a receiver for receiving a first acknowledgment, according to a lower layer protocol, transmitted from the destination network node after receipt of the first data packet by the destination network node, wherein
the transmitter determines that the destination network has received the first data packet without error based on the first acknowledgment received by the receiver, wherein the transmitter does not wait for a subsequent acknowledgment from the destination network related to the receipt of the first data packet before transmitting a second acknowledgment, according to the higher layer protocol, to the source network node based on the first acknowledgment received by the receiver.
