Given is the following scenario.

• Transfer from Node A to Node B over five hops
• Packet header for datagram and virtual circuit switching = 30 octets
• Packet size = 530 octets (30 octets header plus 500 octets data)
• File size = 5000 octets
• Circuit switched packet header = 0 octets
• Propagation delay = 0.05 msec.
• Link rate = 10 Mbps
• Virtual circuit and circuit switched setup time = 0.5 milliseconds
• Virtual circuit and circuit switched teardown time = 0.1 milliseconds
• Packet processing time for datagrams = 1.15 milliseconds
• Packet processing time for virtual circuit switched packets = 0.55 milliseconds
• Packet processing time for circuit switched packets = 0

Assume datagram switching. If the link rate is increased towards infinity, what would be the time in seconds to fully transfer the file?
