Description
Technical field
The present invention relates to communication technical field, specifically is the method for building up and the network equipment of WIFI network user's model.
Background technology
Along with the development of technology, the business in WIFI (Wireless Fidelity, a kind of technology of the wireless Internet) network has obtained significant progress: extended to multiple new business such as voice of today, video by original single Internet access service and deposit.
The appearance of new business kind will inevitably propose new QoS (Quality of Service, service quality) requirement to the WIFI network, and for example: speech business requires very high to the time-delay of network and shake, and not too responsive to the losing of network, wrong bag and transmission rate etc.; Video traffic then requires high bandwidth and transmission rate, and not high to time-delay or the like index request.
For the QoS to these new business classifies and manages, IEEE (IEEE-USA is an international electronic technology and information science engineer's a association) has worked out corresponding standard specially---IEEE 802.11e Medium Access Control (MAC) Quality of ServiceEnhancements (service of IEEE 802.11e medium access control quality strengthens standard).
IEEE 802.11e standard has adopted a kind of new channel access mode: EDCA (EnhancedDistributed Channel Access, the enhanced distributed channel visit), in this standard, the character of the data that WIFI equipment sends is divided into four classes with the type of visit---Background (background), Besteffort (best effort), Voice (sound), 8 priority levels of Video (video).Every type all has the relevant parameter of following QoS: CWmin (minimum competition window); CWmax (maximum contention window); TXOP Limit (send opportunity restriction); AIFS (arbitration frame interbody spacer).The definition of these parameters be described below:
In IEEE 802.11e standard, STA (being Station, standing, is the user terminal among the WLAN, Station with can accesses network after AP is related; ) can from Beacon (beacon) bag of target AP, obtain the relevant information of QoS, EDCA Parameter set (enhanced distributed channel access parameter system) in the Beacon bag and QoS Capbility (quality of service capabilities) comprise these and obtain the relevant information of QoS.Behind the STA access network, it is not that the channel idle that detects medium just can send message, but need at first wait for the extra time period (AIFS), and then generate a random number between CWmin and CWmax to carry out avoidance mechanism, after avoidance mechanism finishes, if channel is still idle, then obtain a TXOP (transmission opportunity, Transmission Opportunity), in the time period of TXOP, STA just can send message.If STA ignores the channel that stand-by period malice takies medium by other means, AP can be by relatively it inserts rank relevant wait pending data and the actual data of waiting for that send and find so, and takes sanction measure for network foundation is provided.
For some data, voice class data for example, because it is very sensitive to delaying time, it is smaller therefore to wait for that (AIFS) value of extra time period should be provided with; And for the data of Email and FTP (File TransferProtocol, file transfer protocol (FTP)) class, it is bigger that the AIFS value should be provided with.Like this, the voice class data just can begin the network competition in next stage quickly than not too responsive communication.By that analogy, high priority type data should have low CWmin and CWmax (it should be noted that, for the data that guarantee low priority not by complete closed, need to guarantee AIFS value that the high precedence data are provided with and the addition of CWmax value with should greater than for the AIFS value of low precedence data setting and the addition of CWmin value with).
After taking above-mentioned media access method and configuration, can guarantee that the data of high precedence in most of the cases can obtain the authority of accesses network.
Except to waiting for that the extra time is provided with, in order to guarantee overall efficiency of transmission, the IEEE802.11e standard also limits the TXOP of Various types of data, for example, the TXOP of voice class data restriction just should very little (very short because of the voice class packet), and, bigger TXOP restriction should be set for FTP, Email and network data.
In order to guarantee more users, but not the interests of the high QoS service-user of minority, AP can carry out some restrictions for the business of high priority, and for example, total network capacity or total access number can not surpass certain value.In IEEE 802.11e standard, AP can come the Control Network workload by using transmission specification (TSPECs): when a STA need send the message of certain data type, he need send a transmission specification request to AP.This request will specify data volume that this STA applies for for the transmission of such data and the maximum delay that can bear.Request hereto, AP will respond based on following two kinds of considerations:
Access strategy based on channel utilization: calculate all high priority AC (access category that inserted in 1 second, the access rank) time of busy channel, and request is with the time of the AC busy channel of high priority access, the two addition, if be less than or equal to user configured maximum channel holding time, then allow this stream to insert with the priority of request.Otherwise, the refusal request.
Access strategy based on number of users: if client terminal quantity adds the client that request inserts among the high priority AC, be less than or equal to the maximum number of user of user configured this high priority AC, then allow the request of this stream.Otherwise, the refusal request.If a client inserts AC-VO (AC-sound) and AC-VI (AC-video) priority service stream simultaneously, insert the number of client and calculate by 1.
If an application goes whistle, the STA that files an application just no longer sends the data of this access type, and must be attached to the data of this access classes in the low data of priority level.
IEEE802.11e has defined multiple access style so that the control of QoS, and AP can control the total amount of every kind of access style.
In actual applications, the present AP upper limits that adopt pre-configured mode to determine various access style users more, for example, certain AP may carry out following configuration---and access style A allows N user at most, and access style B allows M user (generally being the strategy that adopts based on number of users).
Yet above-mentioned way exists a difficult problem---that is exactly how to guarantee that the determined various access control type upper limit can farthest satisfy user's demand, if this problem does not solve, following scene can occur:
The access customer number order upper limit that priority A, B disposed is 10, but in fact 12 category-A users are arranged, and 5 category-B users ask to insert.Although the ability of AP may be able to guarantee simultaneously 12 category-A users and 5 category-B users' QoS, owing on be limited to 10, so just cause having 2 category-A users must accept the degradation of QoS;
The user of same-type is also different to taking of bandwidth, for example IPTV is other type of AC-VI level, but but be divided into high definition (more than the 10Mbps) and SD (2Mbps) according to coded system, if simply calculate according to number of users, then might cause under the constant situation of user's upper limit to bandwidth take that AP head and shoulders above can provide, thereby cause whole QoS to descend.Particularly for the WIFI network of large scale deployment, can not understand clearly around certain concrete AP user personality as: in which terminal, these terminals can be used the demand of which type of service and these service to bandwidth, QoS, in addition, can not understand the Changing Pattern of these characteristics.Thereby more can cause whole OoS to descend.
