Question: As shown in Figure, frames are generated at node A and sent to node C through node B. A B C Figure. Configuration for problem

As shown in Figure, frames are generated at node A and sent to node C through node B. A B C Figure. Configuration for problem Here, - The data rate between A and B is 300kbps, - The propagation delay is 3s/km for both lines, - There are full duplex lines between the nodes, - All data frames are 3000 bits long; ACK frames are separate frames of negligible length, - Between A and B, a sliding-window protocol with a window size of 6 is used, - The buffers of node B are not flooded, - There are no errors. a. Determine the minimum data rate required between nodes B and C so when stop-and-wait is used between B and C. b. Determine the minimum data rate required between nodes B and C so when a sliding-window protocol with a window size of 3 between B and C
