My school is a student apartment, PC owns about 1000 units. Using DHCP assigned IP address, with 4 C class addresses, the actual number of addresses available is about 1000. Because of the frequent presence of private DHCP servers in the building, a large number of hosts cannot be assigned to legitimate IP addresses, and because a significant
is also a classic of circuit switching: when users require sending information, the switch establishes a physical data transmission channel with a fixed time slot between the caller terminal and the called user terminal. This channel is a fixed bandwidth, regardless of whether there is data transmission or how big the data transmission is, it occupies and only occupies the fixed bandwidth until the caller terminal and the called user terminal terminate the connection.
