Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem of the prior art, embodiments of the present invention provide a traffic statistics method and a switching device.
The following first explains the traffic statistical method provided by the embodiment of the present invention. Referring to fig. 1, a flow chart of a traffic statistic method according to an embodiment of the present invention is shown. The method is applied to the switching equipment, and the method can comprise the following steps:
s101: an interface board of the switching equipment receives a flow reporting message from the AP and sends the flow reporting message to a main control board of the switching equipment; the flow reporting message is a message with wireless tunnel encapsulation, and carries an AP (access point) equipment identifier and AP flow size information;
s102: the main control board receives a flow reporting message from the interface board;
s103: and the main control board integrates the AC to extract the equipment identifier of the AP and the flow size information of the AP from the flow report message, and correspondingly stores the equipment identifier of the AP and the flow size information of the AP.
In the prior art, when an interface board of a switching device receives a data packet from an AP, the interface board forwards the data packet to a next-hop device according to a forwarding table, and the data packet flowing through the interface board may come from other devices as well as the AP, so that the switching device cannot distinguish which traffic flows are from the AP and which traffic flows are from other devices, and thus cannot count the traffic flows of the AP.
In the embodiment of the present invention, first, the data traffic flowing through the AP itself is counted by the AP, and a traffic report packet with wireless tunnel encapsulation is formed according to the traffic size information obtained by the counting and the device identifier of the AP. Then, when the preset reporting condition is met, the AP sends the traffic reporting message to the switching device. Then, the interface board of the switching device receives the traffic report message.
In addition, because the interface board has the characteristic of uploading the message with the wireless tunnel encapsulation to the main control board in the switching equipment, after receiving the flow report message, the interface board does not forward the flow report message, but uploads the flow report message to the main control board in the switching equipment. The interface board may send the flow report message to the main control board through the exchange screen or the communication cable.
And then, the main control board integrates the AC to extract the device identification and the traffic size information of the AP from the traffic report message, and correspondingly stores the device identification and the traffic size information of the AP, thereby completing the statistics of the AP traffic.
That is, the switching device can count the traffic of each AP which the switching device is responsible for controlling, by using the traffic counting method. In addition, the main control board of the switching equipment is integrated with the main control board integrated AC. The main control board integrates the AC to analyze the flow reporting message, that is, the switching device can analyze the flow size information of the AP, so that the flow reporting message does not need to be forwarded to an independent access controller AC for analysis, a communication link through which the flow reporting message passes is short, and the speed of acquiring the flow size information of the AP is improved. In addition, corresponding decisions can be made according to the flow of the AP obtained through statistics.
In the present invention, the main control board integrated AC may be: the module is integrated on the main control board and has the whole set of functions of the access controller AC, and can execute flow statistic operation under the call of the main control board.
It is worth noting that the device identification of the AP includes but is not limited to: the IP address of the AP and the product identification serial number of the AP. The traffic size information refers to the number of bytes flowing through the communication interface in a unit time or a preset time period. The traffic report packet with wireless tunnel encapsulation may utilize: the control and configuration of the wireless access point are obtained by CAPWAP protocol encapsulation, and under the condition, the AP can send the flow report message to the exchange equipment through a CAPWAP tunnel between the AP and the exchange equipment.
In addition, the preset reporting condition may be: reaching the preset reporting time; the following steps can be also included: the traffic information obtaining request sent by the switching device is received, but is not limited to this.
For clarity, a specific example of the traffic statistical method provided in the embodiment of the present invention is described below with reference to a network structure diagram of a wireless networking shown in fig. 2.
It is assumed that the wireless networking includes the terminal 201, the terminal 202, the terminal 203, the AP211, the AP212, the AP213, and the switching device 200 as shown in fig. 2, wherein a main control board integrated AC is integrated in a main control board of the switching device 200, and the switching device 200 includes, but is not limited to, a core switch. In addition, it is assumed that in the wireless networking, the terminal 201 can surf the internet through a wireless signal transmitted by the AP 211; the terminal 202 can surf the internet through the wireless signal transmitted by the AP 212; the terminal 203 can surf the internet through the wireless signal transmitted by the AP 213; also, the AP211, the AP212, and the AP213 may communicate with the switching device 200.
Then, in one implementation, the AP211, the AP212, and the AP213 may monitor the traffic flowing through themselves at a set point in time or period of time, thereby obtaining the traffic size information. Then, each AP encapsulates the traffic size information and the device identifier thereof, and encapsulates the traffic size information and the device identifier thereof to obtain a traffic report packet with wireless tunnel encapsulation. Then, each AP may send a traffic report packet corresponding to the AP to the switching device 200 according to the communication address information of the switching device 200.
Furthermore, the switching device 200 may receive the traffic report messages from the AP211, the AP212, and the AP213 through the interface board, and upload the traffic report messages to the main control board of the switching device 200 through the interface board. Then, the main control board of the main control board integrates the AC to analyze the traffic report messages, so as to obtain the device identifier of the AP and the traffic size information of the AP, which are carried in each traffic report message. And then, the main control board of the main control board integrates the AC, and correspondingly stores the equipment identifier of the AP and the flow size information of the AP carried in each flow report message, thereby completing the statistics of the AP flow.
For example, it can be stored as: (device identification of AP211, traffic size information of AP 211), (device identification of AP212, traffic size information of AP 212), and (device identification of AP213, traffic size information of AP 213).
In this way, when the switching device 200 receives a traffic size information acquisition request for the AP211 sent by a technician, the switching device 200 can quickly feed back the traffic size information of the AP211 to a device corresponding to the technician, so that the technician can quickly obtain the traffic size information of the AP 211.
In addition, each AP may report a plurality of traffic report messages to the switching device 200, for example, the AP211 obtains the traffic size information L1 based on the first preset time point, encapsulates the traffic size information to obtain one traffic report message, and sends the traffic report message to the switching device 200. Then, the AP211 further encapsulates, based on the traffic size information L2 monitored at the second preset time point, another traffic reporting message, and sends the traffic reporting message to the switching device 200.
Therefore, in another implementation, the switching device 200 may also count the total traffic flowing through any AP according to all traffic report messages from the AP, and the specific operation may be: the main control board of the switching device 200 integrates the AC, accumulates the traffic size information corresponding to the device identifier of the AP to obtain an accumulated traffic value corresponding to the device identifier of the AP, and correspondingly stores the device identifier of the AP and the accumulated traffic value.
This implementation is explained continuing with the previous example: the switching device 200 firstly obtains the traffic of the AP211 as L1 through the main control board integrated AC statistics; then, after receiving the traffic report message from the AP211 and carrying the traffic size information L2, the main control board integrated AC of the switching device 200 may analyze that the traffic of the AP211 is L2, and at this time, the main control board integrated AC may accumulate the L1 and the L2 to obtain the accumulated traffic value L1+ L2 of the AP 211.
In this way, when the switching device 200 receives a traffic sum obtaining request for the AP211 sent by a technician, the switching device 200 can quickly feed back the accumulated traffic value of the AP211 to a device corresponding to the technician, so that the technician can quickly know the traffic sum flowing through the AP 211. In this way, a technician can determine whether to perform an operation of increasing the bandwidth on the AP211 according to the magnitude of the accumulated traffic value of the AP 211; or, whether the traffic of the AP211 is stolen or not is judged according to the magnitude of the accumulated traffic value, and so on.
In addition, in another implementation manner, the switching device 200 may also perform statistics on the total traffic flowing through the AP211, the AP212, and the AP213 through the main control board integrated AC, and when the statistics are completed, the statistics on the wireless data traffic flowing through the switching device 200 itself are also completed. This is because traffic flowing through the AP211, the AP212, and the AP213 flows through the switching device 200, and traffic flowing through the AP211, the AP212, and the AP213 belongs to wireless data traffic.
The way to count the total traffic flowing through AP211, AP212, and AP213 may be: the switching device 200 counts the accumulated traffic value of the AP211, the accumulated traffic value of the AP212, and the accumulated traffic value of the AP 213; then, the switching device 200 may sum the accumulated traffic value of the AP211, the accumulated traffic value of the AP212, and the accumulated traffic value of the AP213 through the main control board integrated AC, so as to obtain a wireless data traffic value flowing through the switching device 200. In order to facilitate the subsequent technicians to obtain the wireless data traffic value quickly, the main control board integrated AC of the main control board may store the wireless data traffic value.
In addition, when the switching device 200 establishes communication connections with the AP211, the AP212, and the AP213 through the access switch a (not shown in fig. 2), the access switch a is likely to be connected with a wired device (e.g., a computer), that is, the switching device 200 may also receive wired data traffic. In yet another implementation, the switching device 200 may also perform statistics on the wired data traffic flowing through itself, where the statistics are as follows: the interface board of the switching device 200 counts the total traffic value flowing through the interface board and sends the total traffic value to the main control board. The main control board receives the total traffic value, and the main control board integrated AC counts the total wireless authentication traffic value received by the main control board integrated AC, where the total wireless authentication traffic value is the sum of the authentication information traffic values sent by the AP211, the AP212, and the AP213 to the switching device 200. Then, the main control board integrated AC of the main control board subtracts the wireless data traffic value from the total traffic value and subtracts the total wireless authentication traffic value to obtain the wired traffic value flowing through the interface board, and then the main control board integrated AC can store the wired traffic value.
In addition, in order to avoid the situation that the traffic of the AP cannot be counted because the traffic size information of the AP is lost when the main control board of the switching device 200 is powered down or fails, in another implementation manner, the data stored in the main control board integrated AC may be synchronized to the standby main control board AC. Therefore, the safety of the flow information of the AP, the accumulated flow value of the AP, the wireless data flow value and the wired flow value can be ensured.
It should be noted that, the traffic report carries, in addition to: the device identifier of the AP and the traffic size information of the AP may also carry: monitoring time points/monitoring periods, etc., although not limited thereto. Wherein, when the flow report message also carries: when monitoring time points/monitoring time periods, the main control board of the main control board integrates the AC to correspondingly store the equipment identification of the AP, the flow size information of the AP and the monitoring time points/monitoring time periods corresponding to the flow size information, so that more detailed AP flow information can be obtained through statistics.
In summary, by applying the embodiment of the present invention, the switching device can perform statistics on traffic of a single AP, traffic of all APs controlled by the switching device, and wired traffic flowing through the switching device.
