1. A factor in the delay of a store-forward packet-switching system is how long it takes to store and forward a packet through a switch. If switching time is 10 micro-second, is this likely to be a major factor in the response of a client-server system where the client is in New York and the server is in California? Please justify it. Assume the propagation speed in copper and fiber is 200,000 km/second, or 200 m/micro-second, and the distance between New York and California is 5000 km. Explain why Solution
