specific Embodiment approach

[0048] The present invention will be further described in detail below in conjunction with the embodiments shown in the accompanying drawings.

[0049] A), QoS packet format

[0050] In this embodiment, if the packet header field is 00, it indicates that the QoS packet is a control packet. The control packet is used for management control, etc., such as admission control, etc., and is generated and terminated by the QoS layer.

[0051] When the packet header field is 11, it indicates that the QoS packet is a valid data packet. The valid data packet carries the valid data from the upper layer, and sends it to the MAC layer after being packaged; at the same time, it receives the data of the MAC layer, unpacks it and sends it to the upper layer.

[0052] B), for the embodiment of the IEEE802.11 product supported by PCF

[0053] periodic real-time business

Abstract

Disclosed a method for realizing the real-time property and QoS of wireless local network is characterized in that: a QoS intermediate layer is added on the MAC layer of IEEE802.11 which is processed by the software; said QoS intermediate layer can supply the real-time property and QoS to the service. Since said QoS intermediate layer is realized by the software of MAC layer of IEEE802.11 without changing the protocol of IEEE802.11, while it applies present protocol of IEEE802.11 and the future improved protocol of IEEE802.11. The former protocol of IEEE802.11 has worse function of classifying the priority level which only defines two services of real-time (non-completing) and completing, without classifying the priority level on the real-time service. But the inventive method supplies classifying priority level on the real-time service for meeting the application demand to mark the priority level on the service.

Description

technical field [0001] The invention relates to a wireless local area network, in particular to the real-time performance and QoS guarantee of the wireless local area network. Background technique [0002] With the development of microelectronics and wireless communication technology, people pay more and more attention to wireless local area network (WLAN), especially in 1997 the international standard of wireless local area network IEEE802.11 (IEEE Std 802.11-1997 Information Technology-telecommunications And Information exchange Between Systems- Local And Metropolitan Area NetworkS-Specific Requirements-part 11: Wireless Lan Medium Access Control (MAC) AndPhysical Layer (PHY) Specifications.) was passed, which promoted the rapid development of wireless local area networks. Wireless local area network is not bound by cables, can be moved, can solve the problems caused by difficult wiring in wired networks, and has many advantages such as flexible networking, convenient expa...
