Computer networks resilience challenges: Routing protocols

Computer networks are the core of the cyberinfrastucture and are endangered by malicious activities and natural disasters. These threats stress the need for a resilient computer networks to ensure business operational continuity and optimum performance. Several aspects affect computer network resilience level such as network topology, routing protocols, and others. This paper demonstrates Redundancy, Fault Tolerance and Resilience concepts within the computer network domain to illustrate the computer networks resilience goals. It also proposes a set of parameters to evaluate routing protocols´ resilience. Results showed that the compounded use of throughput rate, convergence time, and routing protocol table size can be used as to evaluate the routing protocols behavior towards the computer networks resilience.
