Default gateway protection scheme in fault-tolerant IP routing
Oleksandra Yeremenko, Nadia Tariki, Tetiana Vavenko · 2016
The default gateway protection scheme in fault-tolerant IP routing is proposed in the given paper. In solving the technological problem of the fault-tolerant IP routing, it is necessary to solve either mixed integer nonlinear programming problem during minimization of the object function, or nonlinear programming problem with limitations defined. The proposed model also provides the support of load balancing functions on the virtual router interfaces and fault-tolerant routing in the core network. The use of the model for primary and backup routes provides consistency in solving such important tasks as defining the default gateway and routing in transport network allowing to increase availability and fault-tolerance in communications system in a whole.
