You are transmitting a file of 300,000 Bytes. The header sizes of the protocol headers are 20 bytes for the Transport Layer, 20 bytes for the Network Layer and 18 bytes for the Ethernet Link Layer. Also assume the following: ' The maximum size of the transmitted frames is 1518 Bytes on Ethernet (1500 bytes data + i 8 bytes header). Interframe Gap is 9.6 10 sec. and the Transmission rate B is 10 Mbps. Distance between source and destination is 2 Km and velocity V#2-10s mLs First calculate the Total Time required to transmit the whole file a. b. Second calculate the Normalized Throughput
