5. In the figure below, frames are generated at node A and sent to node C through node B. Determine the minimum data rate required between nodes B and C so that the buffers of node B are not flooded, based on the following: a) The data rate between A and B is 100 kbps. b) The propagation delay is 5 s/km for both lines. c) There are full duplex lines between the nodes. d) All data frames are 1000 bits long; ACK frames are separate frames of negligible length. e) Between A and B, a sliding-window protocol with a window size of 3 is used. f) Between B and C, stop-and-wait protocol is used. g) There are no errors. Hint: In order not to flood the buffers of B, the average number of frames entering and leaving B must be the same over a long interval. A 4000 km 1000 km B 5.
