Theme: Data transmission based on channel and packet switching

Comparison circuit-switched and packet

Packet Switching

No stage of establishing a connection (datagram method)

Address and other service information are transmitted with each packet

The network is always ready to receive data from subscriber

Network bandwidth for users is unknown, transmission delays are random

Network resources are used effectively when transmitting bursty traffic

Possible data loss due to buffer overflow

Automatic dynamic bandwidth allocation of a physical channel between subscribers

Switching channels

You must first establish a connection

Location is only required when establishing a connection

The network may refuse a connection to the subscriber

Guaranteed bandwidth (bandwidth) for interacting subscribers

Real-time traffic is transferred without delay

High transmission reliability

Irrational use of channel capacity, reducing the overall efficiency of the network
