Write shorts notes on Sliding Window Protocol

To acquire high throughput rates, protocols employ a flow control technique termed as sliding window. Both, the sender and receiver are programmed to employ a fixed window size that is the maximum amount of data which can be sent before acknowledge arrives. For illustration, the sender and receiver may agree on a window size of 4 packets.

A four-packet window sliding by outgoing data:

(a) While transmission begins

(b) After 2-packets has been acknowledged and

(c) After 8-packets have been acknowledged.
