Question
Considering Automatic Repeat Request, suppose two neighboring nodes (A & B) use a sliding-window protocol with X-bit sequence number. Using Selective Repeat with a window
Considering Automatic Repeat Request, suppose two neighboring nodes (A & B) use a sliding-window protocol with X-bit sequence number. Using Selective Repeat with a window size of Y in the ARQ mechanism, A is a transmitting and B is a receiving node. Use the values of X and Y to show the window positions for the following events of data exchange: a. Create window before A sends any number of frames. b. Show the window after A sends frames = X and receives acknowledgment from B for only first two frames. c. After A sends frames 3 to 8 and B sends acknowledgement of frame 6 to A.
