A system is perfect, and the first month of access is the most dangerous. Especially in the early school season, thousands of students are coming in at the same time, with a variety of equipment, rules running for the first time, any detail that has not been taken into account will be magnified and malfunctioned. We have followed the process of going on to many schools, finding high overlaps in the places where the rollovers take place, basically those types.
The first day of school is a very difficult day for me to prove it.
This is the most classic and easy to predict. For two or three days, students are gathered in school, certified for the first time, and measured at a rate of several dozen times the normal average. Many systems run well, with certified servers full up on their first day of operation, Portal pages can't be turned around, students think the network is broken, phone calls are blown. We have seen a school that has been shut down for almost half a day on the day of school opening, and all the centres are fire-fighting. The way to avoid it is to do stress tests by peak values before going online, not to calculate capacity by mean, and the certification nodes and bandwidths must be left over.
The student list and the reality are not right.
The list of students who come online from the school worker often does not match the actual accommodation in the dormitory. Some students have their bed not updated, some new students are not integrated into the system, and some room numbers do not fit either way. The result is that a bunch of students certify that they have no one or tied the wrong room. These problems occur centrally on the line for days. It is more stable to check the list and dormitory data before the line, leave a quick-recording trail on site, and students reflect that they can make manual retries or fix it on the spot, so that they don’t get off the Internet for days because of a data error.
Authentication page cannot be opened on some devices
Students are equipped with a strange number of brands, tablets, notebooks, games and smartphones. A certified Portal page that is measured only on several mainstream phones may not be able to pop up in some machine or some system version. If you can't jump off WiFi, it will be impossible to connect. The pre-line tests must cover as many machines and systems as possible, especially Andre's various custom systems and cold door brands. For actual negative performances, there is an option for students to have a fixed web site that manually opens the authentication page, posted in dormitory announcements or guidebooks. The more the device compatibility is measured, the less repairs are made when it comes online.
The billing rule makes a mistake when it runs.
The fee rule runs for the first time in a real environment, and it is easy to expose errors that are not detected when testing: no charge is made wrong, no set is taken wrong, there is a problem with processing the billing boundary across the day. If this error is directly applied to the whole school, it is a huge amount of mischarges, which are extremely difficult to fix. It is safe to go online and make the billing rule run on a small scale before running for a period of time, either by recording the actual deduction or by checking it. We have seen items that do not get the full deduction of the gray, and we find the first month's reconciliation to be counted wrong, and the refunds are paid back to soft hands and verbally.
No one can take a complaint.
The first month of the line must be the highest number of complaints in the year, with problems of failure to connect, fees, speed, and problems coming together. If we don’t get a pre-arranged response on who will receive the complaint, how can we sort it out, how long it takes to respond?
The evening peak bandwidth was filled with instantaneous wiring.
The network has a very obvious evening peak, which is 8 to 11 p.m., where students from the entire building are brushing videos, playing games, live broadcasts, and bandwidths are filled in instantaneous, with speed of the net. If the export bandwidth is not calculated before being on line, no reasonable limit is given to each account number in the billing system, the first month's peak is daily and the student is scolded every day. To be able to assess the band ceiling before going online, with a maximum speed limit per account, and avoid individual heavy users widening the whole layer.
The first month of trouble is mostly not technical, but preparatory work. And pressure, list checks, equipment compatibility, billing greyscale, complaint duty, bandwidth planning. These six things will smooth the system out of its most dangerous start before a formal switch is implemented. School dormitory Internet billing systems are often shaped in the first month.
