In which order and at what times are m1 and m2 delivered

In a token ring network: A Each node has to 'grab' the token at a designated time and send or receive a message B Messages can be passed round the ring in either direction C Message tokens can simultaneously be passed around the ring D The message is passed to the correct recipient by a central computer

Distance vector routing is used. Router L receives distance vectors from routers I, H, and K as shown below.(image)  The distance from L to I is 30, from L to H is 10, and from L to K is 9.  Show L’s updated routing table based on the vectors.

Suppose we have switches S1 through S4; the forwarding-table destinations are the switches themselves. The tables for S2 and S3 are as below, where the next_hop value is specified in neighbor form: S2: ⟨S1,S1⟩ ⟨S3,S3⟩ ⟨S4,S3⟩ S3: ⟨S1,S2⟩ ⟨S2,S2⟩ ⟨S4,S4⟩ From the above we can conclude that S2 must be directly connected to both S1 and S3 as its table lists them as next_hops; similarly, S3 must be directly connected to S2 and S4. (a). The given tables are consistent with the network diagrammed in exercise 6.0. Are the tables also consistent with a network in which S1 and S4 are not directly connected? If so, give such a network; if not, explain why S1 and S4 must be connected. (b). Now suppose S3’s table is changed to the following. Find a network layout consistent with these tables in which S1 and S4 are not directly connected. Do not add additional switches. S3: ⟨S1,S4⟩ ⟨S2,S2⟩ ⟨S4,S4⟩ While the table for S4 is not given, you may assume that forwarding does work correctly.…
