Many schools had a detailed bidding document before they chose the campus Internet billing system, and the manufacturer's plan was even better than one, but it was only after running out that the problem never came up on those bright spots, but was stuck in a few places where they didn't even know to ask. These questions were not rare; they were simply easy to get around at the selection stage.——The manufacturer would not have offered to say that the school did not know what to ask.
How the authenticated data are landed
The physical name certification in the educational network environment is not a personal identity card API, even if it is complete. The Cybersecurity Act and Ministry of Public Security Order 82 require explicitly that logs authenticated by the real name of the Internet be kept locally for at least six months: authentication records, online behavior logs, account bindings must be maintained and the log format must meet the requirements for access by public security authorities. Here the question is whether the system can have full logs on its servers or all data stored in the market.——Can the school information centre run the original log when a security incident occurs and needs to be investigated? In several cases, schools use the company SaaS model, which leads to a process of vendor approval.
The integration depth of the account system and the school LDAP/ AD
Schools usually have a system of LDAP or Active Directory accounts based on school and work numbers, with certifications for teaching systems, library systems, OAs, etc."Support LDAP" The most common manufacturer to answer, but..."Support"Some are single-directional, some can map properties (e.g. by stratification of traffic), and others can connect in real time (on the basis of a school separation account). If the system is only built up on a shallow level, then the batch processing of accounts during graduation and start-up will become a manual maintenance nightmare for information centres. To make this clear at the selection stage, it must not be just to look at it."LDAP Conduit"These words ask about the specific synchronous frequency, the configuration range of the attribute map and the connection mechanism for account changes.
High-cum-issued certification performance baseline
The high-level reconnection of the residential areas after the breakup is one of the most intense settings for the campus system. For example, a mid-sized college (8000-12,000 students) will be closed within five minutes before and after 11 pm, while the number of equipment to initiate certification requests may exceed 3000. If the system’s certification service is not properly performed and issued in parallel with local buffers, this peak can directly crush the certification Portal, which means that the student cannot sweep it."Support XX users"The best way to do this is to ask the manufacturer for a physical and test report from a school of the same size, rather than accept the numbers in a programme book.
Offline diagnostic capability
Many of the campus-based system's certified servers are located in school rooms, but there are some programmes that place core billing logic on cloud ends. The problem with cloud-side programs is that, once operators export or the backbone of a campus network malfunction, students cannot complete certification even if they have access to the inner web and the Internet is completely disabled. For schools that rely heavily on the network, the site's resilience is a key indicator. Normally, a offline diagnostic strategy is deployed locally: when it is not possible to connect a billing server, the registered user's session can be maintained for a certain period of time or a backup local authentication channel is activated. This capability was not realized by all the manufacturers, and it had to be specifically identified when selecting and written in the contract.
MultiSSID and VLAN strategy launch capability
The modern campus network is characterized by a multiplicity of SSIDs: student dormitories, teaching areas, libraries, and staff dormitories may be separated by different SSIDs, as well as VLAN on the bottom. If the Internet billing system is able to move different flow strategies based on user identity, authentication source SSID, including bandwidth limits, time-time policies, traffic pack deduction rules. If the system’s strategy is only designed to produce an IP or VLAN particle size, and cannot fine-tune the cross-dimensional dimensions of individual users +SSID, then differential management in the accommodation area and the teaching district can only rely on handheld operators to maintain the matrix, which will be cumbersome later.
Reconciling norms for billing and financial systems
The cost of Internet access in public schools usually requires the use of the school finance system, which means that billing data generated by the online billing system must be imported into the financial system or directly connected to existing collection platforms (e.g. campus card systems, micro-mail/poonums). It is common practice for manufacturers to provide a single pay portal but it is two skins and the school finance system, which are processed manually for bill reconciliation, invoice issuance, refund processes. For high schools with large numbers of students and stringent financial management requirements, this interface is an ongoing problem for Treasury and Information Centres if not well-developed. The contract should include clear correspondence protocols, data formats and delivery criteria for interface documents, which cannot be based on verbal commitments.
Equipment management compatibility with AP manufacturers
Campus access billing systems usually need to be used in conjunction with A/AP devices for strategy release, traffic statistics and user kick-line operations. If the school A/AP is an A manufacturer, but the Internet billing system only fits B at depths, there will be a loss of functionality on the interface: certification alone cannot do fine speed limits or the end state of the kick line equipment does not synchronize. This compatibility issue is often described as being in the selection books."Support to mainstream plant equipment"The manufacturer is required to list the complete lists of the models for the equipment that are suitable for use in the selection phase, and to identify the type of equipment available at the school specifically and request field docking tests if necessary.
These are not particularly complex, but they are at the tender stage, and if the evaluation material is only looking at functional lists and prices, these problems can easily be jumped over. When a link is found to be offline, it will either represent an additional development cost or a long-term burden on the carrier.
