Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
The invention provides a school network optimization system based on a hierarchical structure optimization model, which comprises a campus subnet, a core server, an authentication server and an intranet server, as shown in figures 1-2.
The campus subnet refers to an intranet located in a school. The campus subnets are multiple and can be divided according to dormitory areas, teaching areas, living areas, libraries and various buildings of the school. That is, the campus subnet may include dormitory zone subnet, teaching zone subnet, living zone subnet, library subnet; meanwhile, the dormitory zone subnet may be further divided into a plurality of dormitory zone subnets according to dormitory buildings, such as a first-building dormitory zone subnet, a second-building dormitory zone subnet, and the like, as shown in fig. 2, for each subnet (the illustration in this embodiment is only to give a specific example that the subnet may have a plurality of subnets, and does not represent the number of subnets in an actual application process). The teaching area subnet and the living area subnet are arranged in a same manner.
Each campus subnet comprises a user side terminal device, an optical splitter and a station side terminal device. The user accesses to the user side terminal device through the user side equipment. The station-side terminal device forms a plurality of optical fiber lines by an optical splitter. One end of each optical fiber line is connected with the output end of the optical splitter, and the other end of each optical fiber line is connected with one corresponding user side terminal device and used for feeding back an access request sent by a user side acquired by the user side terminal device to the station side terminal device through the optical splitter.
The campus subnet is in communication connection with the core server. Specifically, the station side terminal device of the campus subnet is in communication connection with the core server, and is used for forwarding the user access request to the core server.
More preferably, a plurality of station-side terminal devices are provided in one campus subnet, and each station-side terminal device is connected to a plurality of user-side terminal devices through one optical splitter. Further, the optical splitter in the present invention includes an N-class optical splitter. A plurality of optical fiber lines are arranged through a hierarchical structure. More specifically, N is less than or equal to 2. That is, the present embodiment maximally employs only two-stage splitting, and the optical splitter includes the first-stage optical splitter and/or the second-stage optical splitter, so as to simplify the network topology of the sub-network. One end of the first-stage optical splitter is connected with the station side terminal device, and the other end of the first-stage optical splitter is connected with the user side terminal device or connected with the user side terminal device through the second-stage optical splitter.
For example, normally, the number of people in a dormitory is generally 4-6, and the optical splitter can be a 1-split 8-optical splitter. In the teaching district, since there may be a plurality of network users, and the resources of each station-side terminal device are limited, the optical splitter cannot be provided with a large number of optical fiber lines, and for example, the optical splitter may be a 1-to-8 optical splitter.
Preferably, the core server is in communication connection with the authentication server, and is configured to perform parsing on the received user access request and send a parsed result to the authentication server. And the authentication server is used for authenticating the analysis result so as to judge whether the user access address is a campus intranet or a campus extranet.
Specifically, when the user access address is the campus extranet, the core server forwards the user access request to the operator network for processing, receives the user access result, and feeds back the user access result to the device at the user end through the station side terminal device and the user side terminal device of the corresponding campus subnet.
When the user access address is a campus intranet, the core server forwards the user access request to the intranet server, so that the intranet server directly processes the user access request. And meanwhile, the intranet server is also used for directly feeding back the obtained user access result to the equipment of the user side through the station side terminal device and the user side terminal device of the campus subnet, so that the access efficiency of the campus intranet is greatly improved.
Preferably, the intranet server comprises an intranet main server and a plurality of intranet sub-servers. One end of the intranet main server is in communication connection with the core server, the other end of the intranet main server is in communication connection with the intranet sub-servers, and the intranet main server is used for receiving the user access request sent by the core server and forwarding the user access request to the corresponding intranet sub-server or processing the user access request.
More specifically, forwarding the user access request by the intranet main server to the corresponding intranet sub-server specifically includes: comparing the idleness of a plurality of internal network sub-servers, and forwarding a user access request to an internal network sub-server with high space degree; or comparing the priorities of the internal network sub-servers and forwarding the user access request to the internal network sub-server with the higher priority. Through setting up intranet main server and a plurality of intranet branch server, can guarantee data processing's efficiency, still can provide the possibility for follow-up system extension simultaneously. Meanwhile, the whole system can be prevented from being broken down when one intranet server breaks down, and the operation safety of the system is improved.
More preferably, each intranet sub-server also feeds back signals to the intranet main server at regular time, so that the intranet main server obtains the resource utilization rate of each intranet sub-server, and the idleness of each intranet sub-server is calculated.
Preferably, there are also a plurality of core servers. The priorities of the plurality of core servers are the same. By arranging the plurality of core servers, the safety of system operation is ensured, and the system operation is prevented from being obstructed when one core server breaks down.
More specifically, the station side terminal device of the campus subnet is further implemented according to a preset random algorithm when sending the user access request to the core server. The preset random algorithm is set according to the network condition and the duty cycle of the core server.
Preferably, in order to limit the access requirements of the user to the external network, the present invention also charges the user for accessing the external network. Specifically, when the authentication server judges that the user access address is a campus extranet, the authentication server also acquires the account information of the user from the system and judges whether the internet surfing expense of the user is enough, and if not, returns a limited internet surfing notice to the core server; if yes, returning a network access permission notice to the core server. The core server is used for feeding back the internet access limit notification to the user side, or forwarding the user access request to an external operator server for processing according to the internet access permission notification.
Preferably, the internet fee of the user in this embodiment is not only an actual fee, but also any virtual currency, and can be set according to the internet time. Aiming at the difference of teachers, students and the like in the access requirements of the external network, the excessive external network access requirements can be ensured by setting the internet surfing cost, and the study or teaching work is influenced. For another example, for students in different grades, the access requirements for the extranet are different, so that the problem that students in lower grades excessively access the extranet to influence the learning of the students is avoided. That is, the invention sets different internet surfing expenses for the demand of the user for accessing the external network, thereby not only ensuring the effective utilization of resources, but also limiting students and avoiding the problem that the learning is influenced by the excessive entertainment; meanwhile, data records of students accessing the external network can be collected subsequently, and data support is provided for teaching contents or other teaching contents.
Preferably, the school network optimization system based on the hierarchical structure optimization model provided by the invention can greatly improve the expandability of the campus network by constructing a hierarchical network topology structure. Specifically, when the campus subnets in the system are increased, each station side terminal device of the newly-increased campus subnetwork is initialized and connected to any one core server, so that the core server notifies each station side terminal device of the newly-increased campus subnetwork to all the core servers, expansion of the campus subnetwork is achieved, and expansion of the campus network is facilitated.
Preferably, the core server in this embodiment is implemented by an ME60 device, the device is a multi-service control gateway, and the device has the characteristics of high performance, large capacity, intelligent service processing and strong convergence, and services that can be carried include not only traditional broadband services, but also strong security control functions, service isolation means, high reliability guarantee, and QoS guarantee capability, which guarantee the carrying of multiple services, and at the same time, the construction cost and operation and maintenance cost of the network can be reduced.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
