Many institutions of higher learning have more than one campus, the main school district, sub-schools, new campuses are scattered in different urban areas, and some schools have secondary schools, institutes, etc. independent campuses.——The unified deployment of the multi-school campuses is an important feature in building a campus network certification system.
Value of unified deployment in multi-school areas: uniform account numbers, unified strategy, harmonized data
The campus network certification system is deployed in a unified manner, with three flats of benefits most directly. The uniform account numbers: the accounts of students open in the main school area are equally available to the sub-school and do not require reopening; the staff members work across campuses and use the same account number to authenticate the Internet.——All school district user data are kept in a user library, students synchronize from the teaching system, teachers synchronize from personnel systems and schools no longer maintain an account number for each school. Strategy is uniform: the school-wide certification strategy, billing packages, access control strategy centralization, the main campus strategy set up, the campus automatically takes effect, there is no need to duplicate it across campuses; and support adaptation to the campus differences——For example, the main campus has a school code certification, additional text message backup for the campus, and each campus can have its own strategic template but is centrally configured and managed on the headquarters platform. Data harmonization: user data, authentication records, central storage of billing records and statistics are available to school management on-line in schools, with operational data such as the number of users, the success rate of certification, bandwidth usage, etc., per campus, by college, by department, by user group, and statistical analysis to support network planning and business decision-making. These three unified managerial efficiency gains are core values for integrated multicadre deployments.
Deployment structure: centralized management, distribution access, cloud-side deployment
The deployment structure of the Multi-School Campus Network Certification System, which is usually used"Centrally managed, distributed access": Management platform and user data centralized deployment (headquarters office or cloud end), NATSHEL_AUTH_GATEWAY and RADIUS services deployed according to campus distribution (local access to campuses). Specifically, headquarters deployment management platforms——Management functions such as user management, strategy configuration, billing management and statistical reports are all centralized at Headquarters platforms. Network administrators in each campus visit the headquarters platform through Web interfaces for day-to-day management. Headquarters can allocate administrator privileges by school district and role. School area managers manage data and strategies only for their own campus.——Each campus deploys NATSHEL_AUTH_GATEWAY and RADIAS service nodes (or reuses the existing Authentication Gateway equipment in this campus) to be responsible for the certification jump, authentication request processing and access rights of users in this campus. Local access node links with the Headquarters platform: user data is synchronized to local nodes in real time (or quasi-real time), local creaking is prioritized when local authentication is done, reducing time delay over campus calls; authenticating logs, billing records are uploaded to centralized storage at headquarters. Cloud end deployment model: If schools choose cloud-side deployment, management platforms and user data are deployed at cloud-ends, schools locally deploy lightweight Authentication Gateway to communicate via the Internet with cloud-side platforms. The benefits of this mode are that headquarters does not need self-built office and server maintenance, flexible extension facilities and suitability for multischool rapid deployment; reliance on Internet connectivity requires an assessment of downgrading options (local cache strategy) for offsite settings. According to the product information of NATSHEL_BRAND V7, the system supports a variety of models such as local deployment, cloud-end deployment, distributional deployments, any dynamic IP access (NAS devices supporting any IP address when cloudy public network addresses are deployed), and distributed deployment can be used for multiple campuses or large-scale scenarios that provide the structural basis for integrated multi-school deployments. The specific structure (local concentration, cloud end, blend) depends on the school’s network conditions (inter-school line or Internet), IT lift capability and budget, which need to be assessed comprehensively in project planning.
Technical highlights of multi-school settings: data synchronization, cross-campus certification and fault segregation
The unified deployment of multi-school campuses has several key points in technology realization. Synchronization of data: the mechanism for synchronizing headquarters user data with local nodes in each campus is reliable——The user adds, changes, disables changes to the campus nodes in real time and avoids that students cannot authenticate the campus after opening the main campus or that the sub-school will remain accessible after account is disabled; there are clear mechanisms for synchronization delays, conflict processing (the same account number is modified simultaneously in both campuses), failure retesting. Cross-school certification: students move from the main campus to the campus using the same account number authentication system that identifies users and correctly distributes the campus's web strategy (VLAN, bandwidth, authentication pages). Harmonization of billing data: cross-school access billing records are aggregated to Headquarters for uniform settlement——Students generate traffic and cost calculations in the main campus and sub-camps respectively, and failure to divide the campuses into separate settlements leads to confusion of accounts. The central management of logs: central storage at headquarters for the school district certification logs, NAT logs, uploading of online behavioural logs to meet audit retroactive requirements for uniform querying and analysis; evaluation of bandwidth occupancy and storage costs for uploading logs. System assessments of multi-school areas or multiple links are to be conducted separately from the rules for the campus network AAA upgrade and the RadiusProxy interface.——The docking of different campuses and links is verified separately, and the results of individual cadets cannot be extrapolated to all campuses.
Implementation elements and common problems for the unified deployment of multi-school areas
The first is to take stock of the existing network equipment in each campus: AC, Bras, switch branding models may differ from one school to another and certification systems will have to match different equipment in each campus.——Support for multi-plant equipment interfaces is a basic condition, and according to V7 system information the system supports docking AC, BRAS, gateways, switchboards of dozens of mainstream manufacturers such as Naka, Nakaeng, H3C, RUCKUS, ARUBA, Cisco, JUNIPER. Second, confirmation of network conditions in schools: whether school campuses are connected by wire or by Internet, how wide and long it is, and influences structural selection (the exclusive conditions allow for centralized deployment, Internet connectivity requires local buffers and downgrading). The third is the harmonization of user data sources: identification of the source of authority for user data in each school district (the main campus teaching system or the respective school area data source), harmonization of data synchronization mechanisms to avoid multi-data sources conflicts. The fourth is a phased move: integrated multi-school deployments recommend phased implementation——Piloting of structures and processes in one campus, then gradually extending to other campuses; pilot campus experience (data synchronization issues, cross-school certification problems, wiring process) is solidised before scaling up.——Headquarters administrators are school-wide, campus administrators run their own campuses, fee collectors, maintenance staff, etc. roles are distributed on a needs basis and based on V7 system information, systems support multilevel competency management (advance roles such as administrators, chargers, maintenance personnel, collaborators), unlimited level of area management and project management cross-cutting, agent independent competencies. Common problems include: delays in data synchronization lead to failed certification across campuses (need to optimize the synchronization mechanism and monitoring synchronization); inconsistencies in school district strategies result in differences in user experience (need to harmonize headquarters norms); migration of historical legacy systems (there is already a self-certified system in the campus) (need to assess collusion and retreat programmes); Log data surges (multi-school logs are concentrated and pressure on storage and querying increases, requiring rational planning of storage structures). The key to these issues is to map the status of each campus at the planning stage, taking into account differences and evolutionary pathways when designing programmes.
Integrated multi-school management and campus network evolution
The centralized accreditation platform is the common entry point for further expansion of the campus network.——When the new campus is connected, it can be quickly accessed by deploying local Authentication Gateway and accessing the Headquarters platform without re-establishing a system; the campus network, in cooperation with operators, interfaces with operational systems such as one cartoon, and compliance with audit requirements can be built on a single platform. From an evolutionary path, many schools are running single campus certification systems, then gradually expanding to multiple campus integrated management, deployment to cloudy ends or mixing cloud structures. The core of the campus network certification system is to be integrated in a unified deployment of multi-school areas, with an expanded structure: the platform will be managed to support multi-School, multi-tenant (managed area by campus); Authentication Gateway and RADIUS services will support distributed expansion; data will be centrally managed but local crevices will be supported. The authentication system that supports these capabilities will be selected, so that the multiple campuses can be deployed smoothly and the campus network continuously evolves.
The campus network certification system is centrally deployed in multi-school areas, with centralized management of the school-wide network through account reconciliation, strategy alignment and data harmonization."Centrally managed, distributed access"Structure——Headquarters centrally deploys management platforms and user data, and campus distributions of NATSHEL_AUTH_GATEWAY and RADIUS service nodes may be implemented using cloud-end deployment models. The implementation should focus on such elements as the data synchronization mechanism, cross-school certification, billing harmonization, centralized log management and fault segregation, inventory of current network equipment capabilities and network conditions in each school district, harmonization of user data sources, and phased implementation. The system should support multi-manufactor equipment interface, multiple-level access management, distributed deployment and cloud end deployment, provide a structural basis for multi-cadre management and continue to expand as campus networks evolve. Specific multi-school deployment programmes require a comprehensive assessment of the existing network in each school district and cannot be separated from direct commitments on-site conditions.
