Abstract
The invention provides a method and a device for controlling service quality in a wireless local area network. Compared with the QoS control method of the prior art, the QoS control of the invention is more equitable and flexible by implementing the corresponding QoS control on a client according to the type of a service flow of the client.
Description
Technical field
The present invention relates to WLAN (wireless local area network) (WLAN, Wireless Local Area Network) technical field, be specifically related among a kind of WLAN client be carried out the method and the corresponding apparatus of service quality (QoS, Quality of Service) management.
Background technology
WLAN technical development at present is rapid, and the scene of its application deployment also more and more widely.The networking model of WLAN wireless network mainly contains fat access point (Fat AP, Fat Access Point) and two kinds of patterns of access controller (AC, Access Controller)+thin access point (Fit AP, Fit Access Point).Wherein AC+Fit AP is suitable for large scale deployment because manageability is strong, is widely used.
The WLAN technology is based on IEEE 802.11 agreements, its employed physical layer and link layer protocol itself exist intrinsic problem, promptly in single channel, exist than the multi-user or when having multiple business, available bandwidth just has decline in various degree, and then having influence on the application of practical business, this problem is that 802.11 agreements cause in the employed competition mechanism of physical layer.
For example, suppose three independent channels of IEEE 802.11b/g, the actual available bandwidth maximum of each channel approximately is 22Mb, if insert 2 clients, each client average bandwidth approximately is 11M, and if insert 10 clients, each client average bandwidth has been exactly 2Mb.Use in a plurality of clients under the situation of same channel,, will seize the too much network bandwidth, and then cause the actual available bandwidth of other client seriously to descend if user's use side is arranged to end (P2P, Peer to Peer) business.
Utilize situation in order to improve the WLAN technology at the transmission bandwidth under the radio frequency interface, realize professional QoS control and management, prior art adopts Wireless Fidelity multimedia (WMM, Wireless FidelityMultimedia) technology and radio open speed limit technology.
WMM is a kind of wireless QoS agreement, is used to guarantee that the message of high priority has preferential transmission right, thereby guarantees that voice, video etc. are applied in better quality is arranged in the wireless network.In the WMM technology, access point (AP, Access Point) (STA, message distribution Station) enters four different formations of priority, is respectively priority voice flow formation, video flowing formation, do one's best flow queue and background flow queue from high to low with client.Message in the high-priority queue is seized the ability height of channel.Prior art is when actual deployment, normally high-priority queue uses different set of service sign (SSID respectively with Low Priority Queuing, Service Set Identifier), concrete by locating a plurality of SSID of manual configuration at AP (or AC), different SSID corresponding priorities differences, client just need be connected on the different SSID when using different priorities professional like this, for example, when the SSID of client by high priority is linked into AP, the request that takies high priority that AP sends at this client is returned and is confirmed response, makes this client can obtain higher transmission priority; Again for example, when the SSID of client by low priority is linked into AP, AP will refuse the request that takies high priority that this client sends, thereby this client can only send data with priority.
In order to prevent the harmful effect of P2P business to wireless channel, prior art is also by adopting radio open speed limit technology, to AP eat dishes without rice or wine carry out speed limit, limited the maximum bandwidth between AP and each client.Certain client is used the influence of the client of same channel to reduce to other, and is made this influence controlled to a certain extent when using P2P professional like this.
There is following shortcoming in the above-mentioned QoS management method of prior art:
When using the WMM technology, different SSID provides the business of different priorities respectively.Client, can insert according to the SSID of employed service selection respective priority when inserting WLAN usually initial, and all uses SSID that used last time access when inserting afterwards usually at every turn.Because the business that client is used not is changeless, therefore may cause the SSID of the current access of client and the business of current use not to match, for example, client but is connected on the SSID of low priority when using voice or video traffic.For addressing this problem, need the client all need be when each the access at the corresponding SSID of concrete service selection.Obviously, this processing mode lacks enough flexibilities.
In addition, radio open speed limit technology makes all clients under eating dishes without rice or wine all be limited under the identical maximum bandwidth, in order to prevent the using client of P2P business to take the too much network bandwidth.Adopt after the radio open speed limit technology, do not use the P2P business client obtainable maximum bandwidth also can only be the maximum bandwidth of being scheduled to.Use after the above-mentioned empty opening rate-limiting processing, can not obtain more bandwidth when the voice of use high priority or video traffic client, therefore, above-mentioned speed limit processing mode is also unfair for the client of not using the P2P business.

Here, for the WLAN of AC+FitAP networking model, the wireless control apparatus under the client is the AC that the Fit AP of this client association is connected; For the WLAN of Fat AP networking model, the wireless control apparatus under this client is the associated Fat AP of this client.
Step 13, depth detection equipment is issued to first wireless control apparatus with first qos policy, and described first qos policy is used to trigger described first wireless control apparatus first client is carried out corresponding QoS control and treatment.
Step 14, first wireless control apparatus receives first qos policy at first client that depth detection equipment issues.
Step 15, first wireless control apparatus are carried out corresponding QoS control and treatment according to described first qos policy to first client.
Each wireless control apparatus among the WLAN has all been safeguarded the client list item, and is as shown in table 1 below.This client list item includes the information (as the MAC Address of client) of the client under this wireless control apparatus, the Basic Service Set (BSS under this client, Basic Service Set) and this client under extended service set (ESS, Extended Service Set).Wherein, for the WLAN of AC+Fit AP networking model, the BSS under this client is specially the MAC Address of the associated Fit AP of this client; For the WLAN of Fat AP networking model, the BSS under this client is specially the MAC Address of the associated Fat AP of this client.
| The MAC Address of client 1 | BSS under the client 1 | ESS under the client 1 |
| The MAC Address of client 2 | BSS under the client 2 | ESS under the client 2 |
| The MAC Address of client 3 | BSS under the client 3 | ESS under the client 3 |
Table 1
In the present embodiment, each wireless control apparatus is set up logic with depth detection equipment and is connected, and connects by this logic, and wireless control apparatus reports the mac address information of the client under this wireless control apparatus to depth detection equipment; Depth detection equipment receives the mac address information of the client that each wireless control apparatus reports, and the corresponding relation between the wireless control apparatus under maintain customer end and the client in view of the above.In the above-mentioned steps 12, described depth detection equipment is obtained first MAC Address of first client from the Business Stream of first client that receives, and according to the described corresponding relation and first MAC Address, determine first wireless control apparatus of the first client correspondence, and then described first qos policy is issued to described first wireless control apparatus.
IEEE 802.11E has expanded the channel access mechanism of former 802.11MAC layer, the client of supporting the wireless network card of 802.11E standard has been installed, the Low Priority Queuing that all is to use of acquiescence sends data, be the arbitration interframe gap (AIFS of client, Arbitration Inter-Frame Space) initial value is a bigger numerical corresponding to low priority, and client also periodically sends the request (this request specifically can be indicated by a predetermined flag position in the protocol massages) that takies high-priority queue, and after the affirmation response that receives this request of reception that AP (or AC) returns, begin to take high-priority queue and send data, be specially: client is after receiving above-mentioned affirmation response, adjust AIFS, AIFS is diminished, and then make the back off time of this client when the competition wireless channel reduce, thereby can obtain more send opportunity, improve the transmission priority of this client data.
In the described control method of present embodiment, the type of the Business Stream that in step 11, identifies not simultaneously, the concrete action that described first qos policy triggers is also different, specifically comprises:
1) when the type of described Business Stream is speech business or video traffic, described first qos policy is used to trigger described first wireless control apparatus and accepts and respond the request that takies high-priority queue that first client sends; The request that takies high-priority queue that first client sends is accepted and responded to described first wireless control apparatus according to described first qos policy; After described first client receives the response of the reception described request that described first wireless control apparatus returns, by reducing AIFS to improve the transmission priority of its data.
The WMM technology adopts and connects access control (CAC, Connect Admission Control) mechanism, the priority of decision client: client periodically sends the request that takies high-priority queue, only be accepted the back client and could use high-priority queue to send data, otherwise can only use Low Priority Queuing to send data in this request.Therefore, when present embodiment is voice or video traffic in the business of first client, accept and respond the request that takies high-priority queue of first client by wireless control apparatus, make the message of the client of winning to obtain high priority, the ability of seizing wireless channel is improved, thereby has improved the service quality of voice or video traffic.
2) when the type of described Business Stream is the P2P business, described first qos policy triggers described first wireless control apparatus described first client is carried out the speed limit processing; Described first wireless control apparatus is according to described first qos policy, described first client is carried out speed limit to be handled: when the Business Stream speed of first client exceeds predefined speed thresholding, exceed the data of described speed thresholding in the first wireless control apparatus discarding traffic stream.The data that abandon will cause the retransmission process of first client, reduce the transmission control protocol (TCP of first client, Transfer Control Protocol) sliding window, the speed that makes the client of winning produce message reduces, suppressed first client to the taking of wireless channel, thereby made and use other client of same channel can compete Radio Resource comparatively liberally.
As can be seen, present embodiment is to carry out speed limit at the client of using the P2P business to handle, rather than carries out speed limit at eat dishes without rice or wine (all clients on eating dishes without rice or wine) and handle, so the processing of the speed limit of present embodiment is more reasonable and fair with respect to prior art.
Here, be AC+Fit AP in the networking model of described WLAN, AC (being wireless control apparatus) can also be issued to the associated Fit AP of first client with first qos policy by AC, by this Fit AP the corresponding speed limit of first client executing is handled.
3) type that detects the Business Stream of first client when depth detection equipment changes outside speech business and the video traffic other into when professional by speech business or video traffic, described first qos policy is used to trigger described first wireless control apparatus to be controlled described first client and carries out series of fortified passes connection, and the request that takies high-priority queue that described first client of refusal sends in the connection process of the series of fortified passes of first client; Described first wireless control apparatus is controlled described first client and is carried out the series of fortified passes connection according to described first qos policy, and the request that takies high-priority queue that described first client of refusal sends in the connection process of the series of fortified passes of first client.Like this, first client is after the connection of series of fortified passes, and its AIFS will revert to the initial value corresponding to low priority, thereby has also just reduced the priority of the data transmission of first client, makes the transmission priority of the client of winning corresponding with type of service.
In the present embodiment, depth detection equipment can periodically repeat above-mentioned steps 11～13, carries out once in for example per 10 seconds, can be complementary with the type of the current business flow of this client at the qos policy of client guaranteeing.
From the above as can be seen, present embodiment is by increasing depth detection equipment in WLAN, the type of the Business Stream of client is discerned, and then according to the type of Business Stream, to the corresponding QoS control of client executing.With respect to the QoS control method of prior art, the QoS of present embodiment control is fair more and flexible.
