Based on the hardware structure, the embodiment of the campus network free flow calculation method is provided.
The campus network free traffic calculation method described with reference to fig. 2 includes the following steps:
s10, responding to the login request of the terminal equipment, and issuing an authentication page to the terminal equipment;
it is easy to understand that, since campus identity authentication needs to be performed on a user using a terminal device to determine the requirement of the user on the internet in a teaching process, a login step needs to be performed, and in this embodiment, an account login step is implemented by issuing an authentication page through the terminal.
S20, receiving an account number and a password input by the terminal equipment on the authentication page, authenticating the account number and the password according to account information in a database, and selecting a corresponding preset flow-free rule according to the account type of the account number in the database;
it should be noted that, a user who can find the corresponding account information in the database is a campus user, and a user who cannot find the corresponding account information is a guest user, for example, for a user who directly closes an authentication page, if the received account and password are null, the user is a guest user, and a user who can find the corresponding account information in the database only needs to execute the corresponding flow-free rule according to the account type recorded in the database.
And S30, calculating free flow according to the statistical data of the flow type of the terminal equipment and the preset flow-free rule.
It is worth emphasizing that the embodiment further implements refined management on the campus network by identifying and counting different types of traffic, for example, for student accounts, a free policy is executed on the traffic only when the traffic is identified as the traffic in the aspects beneficial to learning, such as thesis inquiry, teaching video, etc., and a charging policy is executed on the remaining traffic; and for the teacher account, only when the entertainment video and the game data are identified, the charging strategy is executed for the part of the flow, and the free strategy is executed for the rest of the flow.
The identity of the user using the terminal equipment is confirmed through the authentication page, the campus network is promoted to be utilized in the aspect of improving the campus teaching capacity by setting the flow-free rule corresponding to the campus identity, fine management is achieved through statistics of the flow type of the terminal equipment, and user experience is improved.
Referring to fig. 3, the step of calculating the free traffic according to the traffic type of the terminal device and the preset flow-free rule specifically includes:
s31, obtaining the flow type according to the data flow characteristics and the target Internet protocol address;
it is easy to understand that, since the game traffic, the video traffic and the web traffic are different from each other in terms of the usage environment and usage status of the traffic, different types of traffic can be identified according to their characteristics, and the traffic generated by the ip address known as the video website or the game server can be determined by the ip address accessed by the terminal device.
S32, counting the data traffic of the terminal equipment according to the traffic type to obtain the statistical data;
it should be noted that, when a certain continuous operation is performed through the network, most of the traffic accesses appear in one internet protocol address, so that the classified statistics of the traffic of different operations can be realized only according to the internet protocol address, and then the classified statistics result is further processed according to the traffic type according to the traffic characteristics to obtain the statistical data.
And S33, calculating free flow according to the statistical data and the preset flow-free rule.
It is worth emphasizing that, in this embodiment, the statistical data includes game traffic, video traffic, web traffic, and download traffic, and then the flow-free rule is divided according to the demands of different campus identities for different types of traffic, that is, the preset flow-free rule.
Referring to fig. 4, the step of obtaining the traffic type according to the data traffic characteristics and the target internet protocol address specifically includes:
s34, setting a white list and a black list according to the known learning related website and the entertainment related website, counting the data flow according to different target Internet protocol addresses, setting the white list flow meter as free flow and setting the black list flow meter as charged flow.
It is easy to understand that, in this embodiment, the learned websites are added to the white list in the mode of setting the white list, and the traffic of visiting the websites in the white list is taken as free traffic. .
Specifically, the method further comprises the following steps:
the database caches page data pointed by the Internet protocol address in the white list and caches data reaching an access frequency threshold value in a non-white list;
it should be noted that, because of the particularity of the campus network, in order to reduce the bandwidth consumption of the wide area network and improve the access speed of the campus network to the learning-type website, in this embodiment, the access speed of the learning-type website is improved by caching the websites in the white list which are identified as being beneficial to learning, and by caching the data and the data with a large number of access times, the traffic consumption between the campus network and the wide area network is reduced, and the access speed of the learning data and the hotspot information is improved.
Performing characteristic analysis on the data reaching the access frequency threshold, and when the data reaching the access frequency threshold is non-learning data, taking the flow meter as a charging flow;
it is worth emphasizing that accessing more data may not be learning data, but the data still can help students to recognize the world growth, and caching the data is beneficial to reduce traffic consumption between the campus network and the wide area network, and the network environment for acquiring learning resources of the wide area network is improved to a certain extent, so that caching of the data is reserved at all, but since accessing the data is not helpful to learning, the access traffic to the data still is counted as charging traffic.
And updating the data of the Internet protocol addresses in the white list at regular time, and deleting the non-learning data of which the number of accesses is less than the threshold of the number of accesses for a preset number of days.
It is worth mentioning that, in the embodiment, the cache data is updated 2 hours after the school lights off, and the data exchange is performed with the wide area network by using the idle bandwidth with a small number of network access people, so that the user experience is improved, and the data which is not a hotspot and is not beneficial to learning is cleaned to avoid excessively occupying the storage space of the database.
Specifically, the step of obtaining the traffic type according to the data traffic characteristics and the target internet protocol address specifically includes:
counting the data traffic according to different target internet protocol addresses, and counting the connection stability characteristics and the data traffic characteristics of each target internet protocol address;
it is easy to understand that the connection stability described in this embodiment refers to the time when data is exchanged with the internet protocol address, the longer the time when data is exchanged with the internet protocol address, the stronger the connection stability, and conversely, the weaker the connection stability, and the data traffic characteristic refers to the total data amount of data exchanged with the internet protocol address.
Taking the data flow with the connection stability characteristic as stable and the data flow characteristic below a preset average flow as game flow; calculating the data flow with the connection stability characteristic as stable and the data flow characteristic as the data flow above the preset average flow as video flow; taking the data flow with the connection stability characteristic of instability and the data flow characteristic of being below a preset average flow as the webpage flow; and calculating the data flow rate with the connection stability characteristic as unstable and the data flow rate characteristic as the data flow rate above the preset average flow rate as the lower current-carrying capacity.
It should be noted that the game traffic has a feature of low total amount of data with long transmission time, the video traffic has a feature of high total amount of data with long transmission time, the web traffic has a feature of low total amount of data with short transmission time, and the download traffic has a feature of high total amount of data with short transmission time.
Specifically, the step of receiving the account and the password input by the terminal device on the authentication page, authenticating the account and the password according to account information in a database, and selecting a corresponding preset flow-free rule according to the account type of the account in the database specifically includes:
receiving an account number and a password input by the terminal equipment on the authentication page, and authenticating the account number and the password according to account information in a database;
it is worth emphasizing that the database storing the account information and the database caching the internet data and counting the traffic type of the terminal device are isolated from each other in the technical scheme of the application, so as to improve the security performance of the technical scheme of the embodiment.
When the account is authenticated as an administrator, all traffic of the account accessing the Internet is counted as free traffic and the free traffic limit of other accounts can be changed; when the account is authenticated as a teacher, the flow cached by the account accessing database, the webpage flow and the downloading flow are counted as free flows, and a preset number of free flow limits are set; when the account is authenticated as a student, flow generated by learning data cached by the account accessing database is counted as free flow, and the free flow limit is 0; when the account is authenticated as a temporary account, the account can only browse the learning data cached by the database.
It can be understood that the administrator account can reward or compensate other accounts by issuing free flow rate limit, so as to reduce adverse effects caused by free flow rate calculation errors, and meanwhile, as a teacher needs to prepare lessons, look up and download a large amount of data, and need to select videos beneficial to teaching from a large amount of entertainment videos, the flow rate of the teacher account accessing the database cache, the webpage flow rate and the downloading flow rate are measured as free flow rates.
Specifically, the method further comprises the following steps:
and when the game flow and the video flow exceed a preset flow upper limit or no flow is generated within a preset waiting time, executing automatic offline processing on the terminal equipment.
It should be emphasized that, the technical scheme of this embodiment achieves the anti-addiction effect by limiting the game traffic and the upper limit of the video traffic, thereby avoiding the excessive time of entertainment occupying the school time of the students, and improving the duty ratio of the rest time and the learning time of the students in the school time.
According to the method, the technical scheme is further improved by disclosing the specific preset flow-free rule and the flow type distinguishing method, the calculation accuracy of the free flow of the campus network, namely the beneficial flow for learning is improved, and the user experience is improved.
The invention also provides a campus network free flow calculation system, which comprises:
the terminal login unit is used for responding to a login request of the terminal equipment and issuing an authentication page to the terminal equipment;
the authentication charging unit is used for receiving an account number and a password input by the terminal equipment on the authentication page, authenticating the account number and the password according to account information in a database, and selecting a corresponding preset flow-free rule according to the account type of the account number in the database;
