Suppose that two peers are connected to a four- node overlay network interconnected with a ring topology, as shown in Figure 16.11. There are 200 requests per second arriving at one of the peers, and the average service rate is 230 requests per second. Assuming that the time required to establish a connection is 10 ms, that the time to finish the service as soon as the connection establishes is 120 ms, and that there is an equal chance that the peer is connected or not connected: Find the total utilization of the peer.
