Consider a channel that can lose packets but has a maximum delay that is known. Modify Protocol rdt2.1 to include sender timeout

and re-transmission. Informally argue why your revised protocol can communicate correctly over this channel

Answer:

See attached picture.

Explanation:

As the packets are being lost, so the introduction of re-transmission and timeout are used to identify the lost packets and re-transmit them. So, the revised protocol can communicate correctly over this channel.

Can someone please help me in answering this!?! <br> The language is C++
Llana [10]

Here is a somewhat cryptic solution that works:

#include <algorithm>

#include <cstdlib>

using namespace std;

void q(char c, int count)

{

for (int i = 0; i < count; i++) {

 putchar(c);

}

}

void p(int b1, int plusses)

{

q(' ', b1);

q('+', plusses);

}

int main()

{

for (int i = -3; i <= 3; i++)

{

 int pl = min(6, (3 - abs(i)) * 2 + 1);

 p(6-pl, pl);

 i == 0 ? p(0, 6) : p(6, 0);

 p(0, pl);

 putchar('\n');

}

getchar();

}

Take this one step at a time. Your teacher has given you the code for step 1. Now write step 2. Then 3, and so on.

For step 2: if you're using Python v2.x you'd use a line like

guess = int( raw_input( "Take another guess: " ) )

For Python v3.x it would be:

guess = int( input( "Take another guess: " ) )

Break it down into small pieces, it's not a complicated assignment.
