SOLVED: Two neighboring nodes (A and B) use a sliding-window protocol with a 3-bit sequence number. As the ARQ mechanism, 'Go-Back-N' is used with the maximum allowable window size. Assuming A is transmitting, and B is receiving, A has received RR7 from B and sends frames 7, 0, 1, 2, and 3. Show the window positions and the buffer content at A for each of the following separate scenarios:i) After A receives RR1.ii) After A receives RR4 instead.iii) After A receives RR3 instead.iv) After A receiv
