Answer:
End to End Delay = 64 micro second
Explanation:
Given
Bandwidth = 125Mbps
A packet = 1000 bytes
Converting bandwidth from Mbps to bit/s
Bandwidth = 125* 10^6 bits/s
Bandwidth = 125,000,000 bit/s
End to End delay is calculated as
Length of Packet ÷ Bandwidth
Length of Packet = 1,000 byte --- convert to bits
Length of Packet = 1000 * 8
Length of Packet = 8,000 bits
So, End to End delay = 8,000/125,000,000
End to End Delay = 0.0000064 seconds --- convert to micro second
End to End Delay = 64 micro second
