Quality of Service Protection Scheme under Fast ReRoute and Traffic Policing Based on Tensor Model of Multiservice Network

In the paper, a Quality of Service protection scheme under Fast ReRoute and Traffic Policing based on the tensor model of multiservice networks is proposed. The model considers the set of parameters that have to be protected: the bandwidth, the probability of packet loss, and the average end-to-end delay. In the course of solving the formulated task in accordance with the presented model, a result was obtained while ensuring a given level of Quality of Service and Quality of Resilience over both the primary and backup routes in terms of the bandwidth, the probability of packet loss, and the average end-to-end delay in the multiservice network.
