Question :
Suppose we have a packet switched network in which two stations A and B are always separated by four intermediate nodes/switches, i.e., the two are 5 hops apart. Suppose station A wishes to transmit 1 MB (1024 x 1024 bytes) of data to station B using N packets
Suppose that the networking protocol requires the use of a fixed length 64 byte header per packet.
Suppose that all switching times are negligible and that the hop time between nodes is entirely determined by the data rate of 100 kbps.
Calculate the optimal number N of packets that should be used in order to transfer the entire 1 MB data set in the least amount of time.
