A simple medium access control protocol would be to use a fixed assignment time division multiplexing (TDM) scheme. Each station is assigned one time slot per cycle for transmission. For the bus, the length of each slot is the time to transmit 100 bits plus the ene-to-end propagation delay. For the ring, assume a delay of 1 bit time per station, and assume that a round-robin assignment is used. Stations monitor all time slots for reception. Assume a propagation time of 2108 m/s. For N stations, what is the throughput per station for

a. A 1-Km, 10 Mbps baseband bus

b. A 10-Mbps ring with a total length of 1Km

Please give answers and explanations so I can understand how to apply the concept to similar questions
