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 30 m. The distance between host B and the second router is 35 m. The distance between the two routers is 400 m. The propagation speed is 2 x 108 m/sec. The recommended transmission rates are: 3 Mbps between host A and the first router, 200 Gbps between the 2 routers, and 5 Mbps 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
