Host A sends a packet of 1,234 bytes to host B via 2 routers. The distance between host A and the first router is 30m. The distance between host B and the second router is 35m. The distance between the two routers is 400m. The propagation speed is 2108m/sec. The recommended transmission rates are: 3Mbps between host A and the first router, 200Gbps between the 2 routers, and 5Mbps between the second router and host B. Each router spends 1 msec to perform error detection. (a) Show the calculation at what time the last bit of the packet leaves host A? (b) Show the calculation at what time the last bit of the packet reaches the second router? (c) If there is no congestion in the network, show the calculation the total end-to-end transmission delay for host A to send the packet to host B
