2 15 points! Read the Communication Methods section on pages 21-23 of the textbook. Write minimum network latency expressions for sending a message of size L bits over a path of length links in a multiprocessor interconnection network assuming each link has bandwidth B bps for the following communication methods: packet switching (the original message of size L bits is divided in packets each of size p bits), virtual cut-through (header field of length Lh bits) and wormhole routing (flit of size Lfbits). Assume a hardware/software overhead of to seconds at each node along the path
