Circuit Switching, Message Switching and Packet Switching
Switching
is a technology to connect two end-points.
In
circuit switching a physical path is set up between two end-points duration of
the connection.
In
message switching no physical path is established. The message is stored and
forwarded to the destination.
In
packet switching no physical path is established. The message is divided into
packets, stored and forwarded to the destination.
Packet
switching can reduce delay and improve throughput.
