Difference between circuit switching and packet switching. Message switching is a connectionless network switching technique where the entire message is routed from the source node to the destination node, one hop at a time. The two most common switching methods are circuit switching and packet switching. Here, the message is divided and grouped into a number of units called packets that are individually routed from the source to the destination. After a small connection setup phase only short compared to full addresses connection identifier are used per packet. Any message exceeding a networkdefined maximum length is broken up into shorter units, known as packets, for transmission. This is the process by which a single message or chunk of data is cut into smaller segments, each wrapped in its own packet headers and sent independently to the destination, where the pieces are reassembled.

Packet switching has reduced the messageswitching delay by a factor of three. Message switching is still used for telegraph traffic and a modified form of it, known as packet switching, is used extensively for data communications. Once all the packets forming a message arrive at the destination, they are recompiled into the original message. Circuit switching vs message switching vs packet switching. Before the advancements in packet switching, message switching acted as an efficient substitute for circuit switching.
