Stop and wait protocol
R=transmission rate S=signal speed D=Distance between sender and receiver T=time to create one frame F=number of bits in a frame N=number of data bits in a frame A=number of bits in an acknowledgement F>N Q.1 Calculate the channel utilization My take: (F/R) / (F/R + 2*D/S + A/R ... .2 Calculate the effective data rate. My take: ( (F/R) / (F/R + 2*D/S + A/R + 2*T) ) * (N/F)

Efficiency in ethernet
Consider a 10 Mbps Ethernet LAN that has stations attached to a 2.5 km long coaxial cable.Given that the transmission speed is 2.3*10^8 m/s, the packet size is 128 bytes out of which 30 bytes are overhead,find the effective transmission rate ... for the calculation of the effective transmission rate I should consider just the date bytes(not the overhead) i.e 128-30=98 bytes.
