Numerical of Flow Control Protocols

In Numerical of Flow Control Protocols, mostly need to calculate efficiency. Before to calculate efficiency, lets learn all basic factors in protocols  

Stop and Wait

Go Back N Selective Repeat
Only one frame can transmit at a time Multiple frame transmission at a time Multiple frame transmission at a time
Sender window size =1 Sender window size = 2K-1 Sender window size = 2K-1
Receiver window size =1 Receiver window size =1 Receiver window size = 2K-1

Note: K is the number of bits to represent the window size)

To find the Efficiency of any protocol use the any of following formula
