Abstract
The invention discloses a method for receiving and sending AP system data by using inquiry mode, and the method comprises the steps as follows: (1) inquiring hardware state register; (2) judging whether there is the received data frame, if yes, processing the step (3), otherwise, processing the step (4); (3) reading the data from the wireless card cache; (4) judging whether the sending list is empty and the wireless card has resource, if yes, processing the step (5), otherwise, processing the step (6); (5) reading the data from the sending queue, copying the data in the wireless card; (6) inputting the processed data in the sending queue. According to the method, the data receiving and sending control capability is raised while the work efficiency is guaranteed.
Description
Technical field
The present invention relates to data transmit-receive field, be specifically related to a kind of method adopting inquiry mode to realize the transmitting-receiving of AP system data.
Background technology
The development of the Internet has entered the stage of a comparative maturity, network has greatly enriched the behavior of people easily, efficient informatization platform makes all manifold operating efficiencies such as enterprise, government, campus be greatly improved, simultaneous mode of working have also been obtained very large improvement, and the degree of dependence of all trades and professions to network is also deepened day by day.At us at any time all in the network used, from carrier network to enterprise network, campus network etc., local area network (LAN) can be described as one of most widely used system, as the basis of local area network (LAN), ethernet technology is also constantly being improved, from 10 million to hundred million, gigabit, gigabit Ethernet, ethernet technology is more and more ripe, throughput is increasing, plays very important role in data communication field.
WLAN (wireless local area network) based on IEEE802.11b agreement is the emerging field in data communication, the wireless broadband Internet access function that it provides meets user to a great extent and is moving the demand to Wireless Data Transmission broadband access in (low speed) situation, there are huge market prospects, nucleus equipment-the WAP (wireless access point) of WLAN (wireless local area network), the quality of its performance will directly affect power system capacity and the traffic handing capacity of network, and the research of WAP (wireless access point) has great importance for the application & development of WLAN (wireless local area network).
Current AP system mainly adopts interrupt mode to carry out data transmit-receive, although this data transmit-receive mode can reduce workload, reduce the requirement to the disposal ability of CPU, but the control ability of this mode to data transmit-receive is more weak, the requirement such for QoS implements more complicated.
Summary of the invention
The object of the present invention is to provide a kind of method adopting inquiry mode to realize the transmitting-receiving of AP system data, solve the current control ability of AP system data transmitting-receiving mode to data transmit-receive more weak, the requirement that QoS is such is implemented to the problem of more complicated.
The present invention for achieving the above object, realizes by the following technical solutions: a kind of method adopting inquiry mode to realize the transmitting-receiving of AP system data, comprises the following steps:
(1) hardware status register is inquired about;
(2) judge whether the Frame of reception, if had, then carry out step (3), otherwise carry out step (4);
(3) from unruled card buffer memory, data are read;
(4) judge whether that transmit queue is not empty and unruled card has resource, if so, then carry out step (5), otherwise carry out step (6);
(5) read data from transmit queue, copy in unruled card;
(6) data processed put into transmit queue.
Further, the detailed process of described step (1) is:
(11) determine to be which position for store frames of data in register;
(12) judge whether these positions of store frames of data change.
Further, the detailed process of described step (3) is:
(31) Frame received is sent into buffer memory in unruled card;
(32) Frame in unruled card buffer memory is read.
Further, the detailed process of described step (5) is:
(51) because the data of transmit queue are not empty, now the data of transmit queue are read;
(52) data read are copied in unruled card again.
Further, after completing described step (6), automatically enter step (1), and constantly circulate.
The present invention compared with prior art, have the following advantages and beneficial effect: the present invention adopts inquiry mode to carry out data transmit-receive, when cpu performance is enough, by arranging different priority to transmit queue, under the prerequisite of guaranteed efficiency, the control ability to data transmit-receive can be improved.
Accompanying drawing explanation
Fig. 1 is the block diagram of system of the present invention.
