Exercise 2. An Ethernet switch transmits frames at a transmission rate of 10 gigabit per second (Gbps). The frame average length is 900 bytes. The transmitter utilization is 20%. The average number of frames stored in the switch (including the one in transmission) is estimated to be 150. A) Compute X, defined as the frame average transmission time [pt. 10]. B) Compute T, defined as the average time a frame spends in the switch at steady-state (T includes both waiting and transmission time) [pt. 10)
