Task 1

Consider the two topologies given below, where the link colors represent the different types of links, as explained in the scenario.


        

Write an essay on the comparison between the two network topologies above. When you write it, consider yourself preparing a report for the Bank CEO, who may not have the appropriate background to understand detailed mathematical formulas. Compare the two tolopologies on the basis of:

  • Overall reliability and costs.
  • Fairness: is any one Bank branch clearly favored or disfavored? What consequences could this have under highly probable failure scenarios?
  • Waste: is any one link excessively reliable (and more costly) when not needed?
  • Balance: are there disjoint subgraphs that have notoriously different degrees of connectivity? What consequences may this have for the Bank operations?
  • Other factors: you are welcome to include other factors that you may judge important.
