Instructions and help about Osmosis In Pocket Switched Networks

The applications, like Google chrome, Skype, Outlook, that need Internet to function are called network applications. In a network application, the end systems or hosts need to send data to each other over the Internet. The data can be an image, audio, video or a text file. Instead of sending the whole file at once, it is divided into small data units at the source, say 1 MB, and are called packets. These packets, then, move over a network of packet switches to reach the destination host. Packet switches can be routers or link-layer switches. This method of data transmission over a network of packet switches in the form of small data units or packets is called packet switching. Consider two hosts connected to each other via a network router. Host A wants to send an image to host B. So host A divides the image file into three packets each having L-bits and starts sending a packet at a rate of R bits/sec. Therefore, the total time required to transmit L-bits or one packet is L/R seconds.
