Question

In th sliding window protocol if the transmission delay is 2ms ,propagation delay 149 ms and 7 bit is fixed for sequence no field ,find maximum efficiency?

Comments

@Gurdeep Saini  ....BECAUSE NOTHING IS MENTIONED IN THE QUESTION WHETHER  GBN OR SR SO SIMPLY CONSIDER THAT WE AR GIVEN 7 BIT FOR SEQUENCE NUMBER FOR WINDOW TO TRANSMIT WHICH CAN GENERATE (0 TO 127 PACKETS) AT ATIME

Ws= 1+2a = 150 (means we can send a maximum of 150 sequence no.)

but this is limited by 7bits fixed for seq. no = 128seq. no.

so maxm eff. = 128/150 = .85 =  85%

 @arvin  ya that is correct way
