Abstract

Communications networks have become a key component to all aspects of a modern organization. Network service disruption can compromise normal operation, even it can threaten survivability of business or enterprise. Because of business risk generated by communication lost, organizations have to planning a dependable infrastructure and configure an architecture that guarantees survivability. This work is focused on tasks that a system has to deploy for assuring continuity on its communications by redundancy. This paper affords a point of view for modelling a redundant network based on graphs. This is proposal of using multi objective genetic algorithms for figuring out an optimal configuration of a communication network taking into account two particular objectives. First, it is related to cost to implement and maintains redundant devices on a network. Second, the availability measured in terms of probability of damage and mean time to fail.
