Dedicated lines exist between location A and location B, and location B and location C. The distance between A and B is 5000 km and between B and C is 1500 km. The technology used for the media provides a propagation time of 10 microseconds per kilometer between location A and location B, and 5 microseconds per kilometer between location B and location C. If the data rate between A and B is 200 kbps and window size is 4 and packets of 125 8 bit bytes is it possible to choose a minimum data rate between B and C to avoid Bs buffers from overflowing? Explain your reasoning. If it is possible then what is that data rate?
