Tunneling through a concatenated virtual-circuit subnet is straightforward: the multi protocol router at one end just sets up a virtual circuit to the other end and passes packets through it. Can tunneling also be used in datagram subnets? If so how?

What is the maximum number of hosts it can handle?ARP and RARP both map addresses from one space to another. In this respect, they are similar. However, their implementations are fundamentally different. In what major way do they differ?In our example transport primitives of Fig. 6-2, LISTEN is a blocking call. Is this strictly necessary?
