1) Using the network in the figure below, give the virtual circuit tables for all the switches after each of the following connections have been established. Assume that the sequence of connections is cumulative; that is, the first connection is still up when the second connection is established. Also assume that the VCI assignment always picks the lowest unused VCI on each link, starting with 0, and that a VCI is consumed for both directions of a virtual circuit. Give explanations for obtaining the following virtual circuit tables. 1. Host A connects to host B 2. Host B connects to host D 3. Host B connects to host E 4. Host C connects to host D 5. Host C connects to host E

Question
1) Using the network in the figure below, give the virtual circuit tables for all the switches
after each of the following connections have been established. Assume that the
sequence of connections is cumulative; that is, the first connection is still up when the
second connection is established. Also assume that the VCI assignment always picks the
lowest unused VCI on each link, starting with 0, and that a VCI is consumed for both
directions of a virtual circuit. Give explanations for obtaining the following virtual circuit
tables.
1. Host A connects to host B
2. Host B connects to host D
