The LAN in Fig. 6 consists of two self-learning Ethernet switches. Initially the switching
tables are empty.
At time t =1 a message is sent from the source H to the destination J. The destination
J then sends a response to H.
At time t =2 a message is sent from the source F to the destination E. The destination
E then sends a response to F.
At time t =3 a message is sent from the source K to the destination F. The destination
F then sends a response to K.
At time t =4 a message is sent from the source I to the destination D. The destination
D then sends a response to I.
i) At time t =1, what is the entry in S1 when the message is sent from the source?
(ii) At time t =1, what is the entry in S1 when the response is sent back from the
destination?
(iii) At time t =1, what is the entry in S2 when the message is sent from the source?
(iv) At time t =1, what is the entry in S2 when the message is sent back, from the
destination?
(v) At time t =2, what is the entry in S1 when the message is sent from the source?
(vi) At time t =2, what is the entry in S1 when the response is sent back from the
destination?
(vii) At time t =2, what is the entry in S2 when the message is sent from the source?
(viii) At time t =2, what is the entry in S2 when the response is sent from the destination?
(ix) At time t =3, what is the entry in S1 when the message is sent from the source?
(x) At time t =3, what is then entry in S2 when the message is sent from the source?
(xi) At time t =3, what is the entry in S2 when the response is sent back from the
destination?
(xii) At time t =4, what is the entry in S1 when the message is sent from the source?
(xiii) At time t =4, what is ten entry in S1 when the response is sent back from the
destination?
