according to the switching mode, the computer network can be divided into
line switching network (Circurt Switching), message switching network (Message Switching), packet switching network (Packet Switching).
our commonly used telephones are line-switched networks, what about message-switched networks and packet-switched networks? What are the examples?
just understand the concept.
first there is circuit switching with independent channels, and then there is the concept of message switching. But in the computer network, TCPUDP is message exchange, it is problematic to achieve message exchange in fact, the message is large or small, the difference is too big, in order to improve the utilization, so the TCP packets are grouped and divided into IP packets, which is called packet switching.
Future networks will all be, ALL Over IP. of IP. Now the phone calls and text messages you send are all transmitted over the IP network.
