This strategy depends on sending messages between stations. Each message is comprised of a source address, a goal address, managerial data and the (data).
At the point when a station sends data, it does so utilizing the source-goal address framework, guiding its message to the goal address. The message is sent through the network starting with one hub then onto the next. Every hub gets the whole message, stores it quickly while recognizing the following hub, and afterward sends it to the following hub. This infers the root goal way is utilized all the while by various messages. Consequently, networks that utilization message switching are known as store-and-forward networks.
Favorable position:
Line productivity is higher than in a circuit exchanged strategy since more than one gadget might be sharing the network transmission capacity.
Gridlock can be diminished as messages are incidentally put away by gadgets on your course.
A need framework for messages can be built up. Low need messages can be deferred on your course so high need messages outweigh everything else on the way to your goal.
A message can be sent to numerous goals. Unicast sending (balanced), Multicast (one to many) and Broadcast (one to all) are bolstered.
Disadvantages:
The message switching strategy doesn't bolster constant applications. Applications with a high connection proportion are influenced by the defer forced in the store-and-forward plan. For instance, message switching isn't suggested for voice service associations.
Store-and-forward gadgets are commonly over the top expensive since they require exceptionally quick, high-limit stockpiling units.
