  1. What is the total time required to send a 50 GB file from Host A to Host B over the below TCP/IP network using Ethernet? 

    Speed of light constants:

    vacuum : 3.0 * 10^8 m/s

    copper : 2.3 * 10^8 m/s

    optical: 2.0 * 10^8 m/s

A The links have the following distance and bandwidth Link 1. Link 2. Link 3. Link 4. Each switch is a store-and-forward switch that introduces the following delays between packets - Switch 1 introduces a 60 µs delay between packets Switch 2 introduces a 50 µs delay between packets Switch 3 introduces a 70 us delay between packets A 2 RTT handshake is needed before data can be transmitted Your answer should be shown in seconds and be accurate to one tenth of a microsecond Link 1 80 m copper An 80 m copper link has a 100 Mbps bandwidth A 2,800 km fiber link has a 20 Gbps bandwidth A 3,500 km fiber link as a 120 Gbps bandwidth A 30m copper link has a 80 Mbps bandwidth Switch 1 Link 2 2,800 km fiber Switch 2 Link 3 3,500 km fiber Switch 3 Link 4 30 m coppe B
