Question: Given is the following scenario. Transfer from Node A to Node B over five hops Packet header for datagram and virtual circuit switching = 30

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?
