Question: Using the example network given in Figure 3.42, give the virtual circuit tables for all the switches after each of the following connections is established.
Using the example network given in Figure 3.42, give the virtual circuit tables for all the switches after each of the following connections is established. Assume that the sequence of connections is cumulative; that is, the first connection is still up when the second connection is established, and so on. Also assume that the VCI assignment always picks the lowest unused VCI on each link, starting with 0.
(a) Host D connects to host H.
(b) Host B connects to host G.
(c) Host F connects to host A.
(d) Host H connects to host C.
(e) Host I connects to host E.
(f ) Host H connects to host J.
Figure 3.42)
Host C 3 Host D 2 Host A Switch 1 3 Host E 0 Host J Switch 2 0 2 Host I Host F Switch 4 3 Switch 3 3 2 Host H Host B Host G
