We wish to send a message of size $150,000$ bytes over the network. There are four hops, each of length $20km$ and running at $100 Mb/s$. Before sending we split the message into $1500$ byte packets. What is the end-to-end delay of the message?
Make following assumptions :
# The switches "store and forward" packets along the path.
# For each hop, propagation speed = speed of light in copper $= c = 2 * 10^8 m/s$.
# The delay over each of the links is identical.
# Net queueing delay is zero.
# Net nodal processing delay is zero.
