A datagram network allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of hops a packet makes per transmission?

 

  1. p^2-3p+3
  2. p^2+3
  3.  3p+3
  4.  p+3
