: End-to-End message transport: (a) without message segmentation; (b) with message segmentation. Networks and Broadband systems Assignment 1 1. This elementary problem begins to explore propagation delay and transmission delay, two central concepts in data networking. Consider two hosts, Hosts A and B, connected by a single link of rate R bps. Suppose that the two hosts are separated by m meters, and suppose the propagation speed along the link is s meters/sec. Host A is to send a packet of size L bits to Host B. a) Express the propagation delay, d prop in terms of m and s . b) Determine the transmission time of the packet, d trans in terms of L and R . c) Ignoring processing and queuing delays, obtain an expression for the end-to- end delay. d) Suppose Host A begins to transmit the packet at time t=0 . At time t=d trans , where is the last bit of the packet? e) Suppose d prop is greater than d trans . At time t=d trans , where is the first bit of the packet? f) Suppose d prop is less than d trans . At time t=d trans , where is the first bit of the packet? g)
