Computer A is sending a 100 kByte long file to Computer B via packet-switching over two consecutive 10 Mbps links of 1000 km length each. Assume that the signal propagation speed on both links is 2.5 x 108 m/s. Furthermore, assume that the maximum length of a packet is 1500 bytes and that Computer A fills each packet to the max, if possible. If transmission starts at time t=0, how long (in seconds) does it

Computer A is sending a 100 kByte long file to Computer B via packet-switching over two consecutive 10 Mbps links of 1000 km length each.
Assume that the signal propagation speed on both links is 2.5 x 108 m/s.
Furthermore, assume that the maximum length of a packet is 1500 bytes and that Computer A fills each packet to the max, if possible.If transmission starts at time t=0, how long (in seconds) does it take until Computer B has received the last bit of the complete file transfer?
Assume that the switch between link 1 and 2 is a "store-and-forward" switch. Furthermore, assume that processing and queuing delays are negligible and no other stations are using the links.
