title: Fault-tolerant multicast routing in infocommunication network with path and bandwidth protection
abstract: The article presents and investigates a flow-based mathematical model of fault-tolerant multicast routing. Under the proposed mathematical model, the technical task of fault-tolerant multicast routing was reduced to the Boolean programming optimization problem. The mathematical model was based on linear optimality criterion and constraints represented by the conditions of single-path routing, flow conservation, multicast connectivity, and prevention of overload and looping. The routing variables
