3. For the following scenarios, calculate the latency (delay) from the first bit of data sent by the sender to the last bit of data received by the destination. Each link has a data rate of 20 Mbps (Megabits per second). The packet size is 5000 bits. Assume that each link introduces a propagation delay of 20 Microseconds. Also assume that a node can begin transmitting data on the outgoing link as soon as it has received the complete packet from the incoming link. (a) A network of two links with a single store-and-forward switch (node) in the path. (b) Same as (a) but in a network of four links connected by three switches (nodes). (c) Same as (a) but assume that the switch (node) can begin transmitting data on the outgoing link after the first 400 bits of the packet have been received.
