PACKET SWITCHING

, INTRODUCTION

What is Packet Switching?
Packet Switching refers to protocols in which messages are divided into packets
before they are sent. Each packet is then transmitted individually and can even
follow different routes to its destination. Once all the packets forming a message
arrive at the destination, they are recompiled into the original message.

, • Each packet is given a header containing information of the destination. Each

packet is forwarded through the network to the destination using this information.

• At the destination the data has to be reassembled received packages.
• It uses packets of fixed or variable size. Each packet contains, header with the
addresses source & destination The size of the packet is determined by the network
and the governing protocol.

• If a station has a longer message to send it breaks it up into a series of small
packets. Each packet now contains part of the user's data and some control
information.
