Question 12
A server S requests to retrieve data from two data centers and , which are located at distances of and meters respectively from the server S. The speed of data travelling through the medium that connects S with is m/sec and that connects S with is m/sec. With the given media for data transfer between S and S , it takes an additional 200 milliseconds for the data to reach S from than it takes from if the complete response is ready only when the data is available to S from both the datacenters. Figure out the value of (in m/sec) in terms of , and . [Note: The data centers send responses only when they receive a request from the server]
