Question

Text: Packet-switching and circuit-switching a) An access switch has a link rate of 1 Mbps (1x106) and supports 35 users using packet switching. Each user generates data at an average rate of 80,000 bytes per minute. What is the average link utilization, i.e., the percentage of time the link is busy sending data? b) An access switch has a link rate of 1 Mbps (1x106) and uses circuit switching with time division multiplexing (TDM) to support 50 users. Assume 10% of the link capacity is used for management overheads. What is the maximum rate (throughput) for each user? c) What is the difference between shared memory and a crossbar switch design? Where is each type of design most applicable?
