Question
Consider the network below. Suppose that this network is a datagram network. Show the forwarding table in router A, such that all traffic destined to host H3 is forwarded through interface 3. Suppose that this network is a datagram network. Can you write down a forwarding table in router A, such that all traffic from H1 destined to host H3 is forwarded through interface 3, while all traffic from H2 destined to host H3 is forwarded through interface 4? Now suppose that this network is a virtual circuit network and that there is one ongoing call between H1 and H3, and another ongoing call between H2 and H3. Write down a forwarding table in router A, such that all traffic from H1 destined to host H3 is forwarded through interface 3, while all traffic from H2 destined to host H3 is forwarded through interface 4. Assuming the same scenario as (c), write down the forwarding tables in nodes B, C, and D.Explanation / Answer
Answer:
a). Data destined to host H3 is forwarded through interface 3
3
b). No, because forwarding rule is only based on destination address.
c)
those two flows (from H1 and H2) must have different VC#s, true for both incoming and outgoing VC#s.
d) Router B
Router C
Router D
Incoming interface
Destination address Link interface H33
