Fault-tolerant IP routing flow-based model

In this paper the fault-tolerant IP routing flow-based model presented. In solving the technological problem of fault-tolerant IP routing it is necessary during minimization of object function to solve either linear programming problem or Boolean programming problem with limitations defined. Proposed model also provides the support of traffic balancing functions on the virtual router interfaces, which also has a positive impact on the availability and productivity of telecommunication system as a whole.
