3. Circle the most correct answer to each of the following questions: A Switched LAN is different from a Shared LAN in that: (A) each node on the Switched LAN gets access to the full bandwidth; (B) each node is on a separate LAN segment; (C) frames sent by a node are forwarded only to the destination node on the LAN; (D) options (A) and (B) above; (E) options (A), (B) and (C) above. Collisions can happen on a Shared...

Q2.3. (15%) Consider sending a file of F bytes over a path of Q links. Each link transmits at R bps. The network is lightly loaded so that there are no queuing delays at any link. The propagation delay on each link is Tp seconds on average. 1. Suppose the network is a packet-switched virtual-circuit network. Assume the VC setup time is Ts seconds. Suppose the sending layers add a total of h bits of header to the file, and...

Consider three LANs interconnected by two
routers as shown in the Figure.
1. Consider sending an IP datagram from host E to Host B.
Suppose all of the ARP tables are up-t-date. Enumerate all the
steps, as done for the single router example in section 6.4.1.
2. Now repeat the previous steps assuming that the ARP table in
the sending host is empty and the other tables are up to date.
