Dispatching method for data packets of multi-rate wireless network, and equipment using same

Abstract

The invention provides a dispatching method for data packets of a multi-rate wireless network, and equipment using the method. The dispatching method comprises the following steps: a wireless access point is used for sorting data packets of a plurality of wireless nodes according to the physical connection rates of the plurality of wireless nodes connected with the wireless access point, so that a plurality of arrays of data packets corresponding to various types can be formed; the throughput of the array of data packets corresponding to each type of wireless node is calculated and distributed; the message types and the priority levels of the data packets are determined, and the starting time and the ending time of the data packets in each array are estimated; and the data packets in each array are dispatched according to the determined priority levels of the data packets and the estimated starting time of the data packets, wherein the data packet having the short starting time in the array according to the calculation is dispatched earlier, and the data packet having the high priority level is placed at the front end of the array. The method provided by the invention can solve the low effect in the multi-rate wireless network, and improve the performance of the wireless system.

Description

technical field [0001] The present invention relates to wireless network communication technology, more specifically, to a hierarchical scheduling method for data packets in a multi-rate wireless network and a wireless management device using the method. Background technique [0002] With the application of wireless local area network (WLAN) more and more widely, this technology is more and more welcomed by people. Initially, the 802.11b scheme designed by the IEEE 802.11 working group works at 2.4Ghz, and the connection rate is 2Mbps. With the continuous upgrading of the design of the IEEE 802.11 working group, the 802.11a scheme works at 5Ghz, and the connection rate is as high as 54Mbps; the connection rate of the 802.11g scheme is still 54Mbps, and its design frequency works at 2.4Ghz, compatible with 802.11b; the latest 802.11n It can work at both 2.4Ghz and 5Ghz, and the rate can be as high as 600Mpbs by using multiple-input multiple-output (MIMO) technology. The IEE...

Problems solved by technology

If the WLAN adopts the TCP protocol, it will become more troublesome to lose a TCPACK packet, requiring multiple retransmission confirmations, which greatly wastes the bandwidth of the system
