![Task2: In packet switching technology the packet size is an import parameter when it comes
to efficiency and reducing the network latency. Let us assume a network which consists of a
sender host and a receiver host at nh hops faraway from each other's (nh-1 routers R).
s>R>R> ..>S. If we assume that all links have a bit-rate B bps and originally the
message to be send from the sender to the receiver is of size L bits.
1) Give the formula to compute the network latency if we assume circuit switching
(switching time per switch is s seconds).
2) Same as in 1) but we assume packet switching with packet size p bits.
3) From 2) drive the best packet size p which give the best performance (minimum
network latency). Hint. One way to find out the minimum of a function f is to find its
derivative f'(0).
4) Verify your result by providing prove example.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8d27752c-955a-44ce-bf3c-477256cec794%2Fcfef020b-5c0f-4e30-a607-b66a885bfdfd%2Fmxie2n_processed.jpeg&w=3840&q=75)
