Transmission control protocol acknowledgement (TCP ACK) message processing method and device and wireless network equipment

Abstract

The invention provides a transmission control protocol acknowledgement (TCP ACK) message processing method, a TCP ACK message processing device and wireless network equipment. The method comprises the following steps of: judging whether a continuous TCP ACK message exists in a message to be aggregated according to a head of the message to be aggregated; when the continuous TCP ACK message exists in the message to be aggregated, processing the continuous TCP ACK message according to a preset threshold value; and sending an obtained frame aggregation queue into a frame aggregation unit for frame aggregation. By the method, the TCP ACK message in the message to be aggregated is processed specially, and then frame aggregation operation is performed, so that resources which are occupied during frame aggregation of the TCP ACK message can be reduced, and the problem of shortage of wireless air interface resources is solved; particularly, a phenomenon that a cache queue is fully filled because of a TCP ACK attack can be avoided; the transmission quality of the TCP message is improved; the throughput of a wireless network is improved; and under the condition that the frame aggregation depth cannot be improved, the resource utilization rate of the wireless network can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a transmission control protocol (Transmission Control Protocol, TCP) acknowledgment (ACK) message processing method, device and wireless network equipment. Background technique [0002] Wireless performance has always been one of the factors restricting the wider application of Wireless Local Area Networks (WLAN). After the 802.11a standard and the 802.11g standard, the 802.11 group is working on the formulation of the 802.11n standard. The 802.11n standard proposes a hard target for performance improvement. Since the 802.11n standard, the data rate of the physical layer (PHY) has been significantly improved, but due to the fixed system overhead of the MAC protocol, these advantages cannot be reflected above the MAC layer. [0003] Any message in 802.11 will be sent as a MAC protocol data unit (MAC Protocol Data Unit, MPDU) when physically sending, and eac...

Problems solved by technology

However, network transparent transmission devices in wireless networks usually do not have filtering operations related to TCP ACK.

When the network condition is bad, a large number of TCP ACKs will be forwarded to the network transparent transmission device. The wireless network transparent transmission device does not filter the MAC layer in 802.11n, and directly sends the TCP ACK to the frame aggregation queue and forwards it to the hardware queue. It will cause frame aggregation queue congestion and consume the resources of wireless transparent transmission equipment
