Message Switching

  • Message switching is also called as Store & Forward technique
  • In this mechanism, a node (usually a special computer) receives a message, stores it until the appropriate route is free, once the path becomes free, then it sends the message.
  • Store & forward is considered, because there is no direct link between sender and receiver.
  • A message is delivered to the node through one path then routed along another to its destination.
