INCREASING ACCESS POINT THROUGHPUT BY EXCEEDING A-MPDU BUFFER SIZE LIMITATION IN A 802.11 COMPLIANT STATION

摘要

An 802.11-compliant device for high throughput is disclosed. A plurality of TCP packets received in a buffer for transmission are stored. The plurality of TCP packets can be aggregated as A-MSDU sub-frames to form a A-MSDU frame in accordance with an IEEE 802.11 standard. Additionally, a plurality of A-MSDU frames can be aggregated as A-MPDU sub-frames to form a A-MPDU frame. The A-MPDU frame is compliant with a number of allowable sub-frames and a maximum size in accordance with an 802.11 standard. The A-MPDU frame is sent for transmission as an IEEE 802.11 packet.

1. A computer-implemented method for exceeding A-MPDU buffer size limitation in a IEEE 802.11 compliant device, comprising:
storing a plurality of TCP packets or UDP packets received in a buffer for transmission; detecting an IEEE 802.11ac transmission channel between the IEEE 802.11 compliant device and a second device; responsive to the detection, switching to a high throughput mode with A-MSDU and A-MPDU frame aggregation, comprising: aggregating the plurality of TCP packets as A-MSDU sub-frames to form a A-MSDU frame in accordance with an IEEE 802.11 standard; aggregating a plurality of A-MSDU frames as A-MPDU sub-frames to form a A-MPDU frame, wherein the A-MPDU frame is compliant with a number of allowable sub-frames and a maximum size in accordance with an IEEE 802.11 standard; and sending the A-MPDU frame for transmission as an IEEE 802.11 packet; detecting that errors in IEEE 802.11ac transmission channel between the IEEE 802.11 compliant device and a second device exceed a threshold of tolerance; and responsive to the detection, switching away from a high throughput mode with A-MSDU and A-MPDU frame aggregation.
