What is the technical side of the "home" Internet provider?

Question

Computer networks

Actually, let's put aside the legal side and, in theory, look at the formation of your own Internet provider for your own personal purposes (not for the sake of selling)? Purely in theory, what might be needed in such cases, not taking into account the connection to the backbone operator?

Answer 1

The question is very broad. At a minimum, there are different types of providers, we will divide them into wired and wireless, different types of connection, different network schemes and, accordingly, different budgets and technologies. What any provider has:
1) Billing - this is the thing that turns on / off access to subscribers, counts money and much more.
2) Monitoring - to monitor the operation of the entire infrastructure
3) There is one or more network cores, where all traffic from clients converges and the channel comes.
Optionally, there are also: BRAS, DSLAM, NAT and a bunch of different hardware, wires, optics, etc.
