Question $8$

$==========$

Consider the stop$-$and$-$wait $($i$.$e$.,$ alternating bit$)$ protocol. Modify the

protocol so that instead of obtaining the data $($i$.$e$.$ the body$)$ of the frame

from the "higher layer", we get it from an array of integers, and the receiver

has an array of integers where it stores the data received. The purpose is to

copy the array in the sender to the array in the receiver $($one element at the

time of course$)$

I.e$.,$ add the following array to the sender:

datasender : array $[$integer$]$ of integer;

ns: integer $/*$ initially $0*/$

I.e$.,$ an infinite array $($hence$,$ the index can be any integer$).$ ns is an index of

which data is the next one to send $($i$.$e$.$ next data to send is datasender$[$ns$]).$

In the receiver, add the following array

datareceiver : array $[$integer$]$ of integer;

nr: integer $/*$ initially $0*/$

nr is an index of where to store the next data to be received

frames will now have the format

frame$($b$,$ x$)$

where b is a bit $(0$ or $1)$ and x is an integer $($from the data array of course$)$ PLEASE NO AI ANSWER
