“…Thus, in [15] it is proposed to carry out the coordinated solution of the problems of load balancing on © O. Lemeshko [16,17] to protect the level of Quality of Service through the bandwidth and average end-to-end packet delay, which is particularly important when serving multimedia flows. In addition, [18] proposed a solution to the problem of fast rerouting of VoIP flows with protection of the Quality of Service, which is perceived at the level of the user (Quality of Experience, QoE), according to the quality rating R. On the other hand, for data traffic is not critical the controlling of the growth of packet delay, but it is important to ensure that it has an acceptable packet loss rate [19,20].…”

“…To ensure consistency in the calculation of the routing variables responsible for implementing fast rerouting on the network, it is important to ensure that the flow conditions are met, taking into account the possible packet loss caused by the queue buffer overload on the network routers. These conditions for the nodes that are part of the primary path (s) have the following form [17]:…”

“…The analysis performed [4, 1114] showed that this was generally concerned with the protection of network bandwidth, which is one of the main QoS indicators. However, a priority area for the development of fast rerouting facilities, especially in multiservice infocommunication networks (ICNs), is to expand the list of Quality of Service indicators for which values are protected along the primary path with adequate reservation of the network resource [15][16][17][18][19]. Reserving network bandwidth, as a primary Quality of Service indicator, should be complemented by the protection of other key QoS indicators, such as average delay, jitter, and packet loss, which is especially important when transmitting multimedia traffic.…”

The subject of research in the article is the processes of fast rerouting with the protection of the Quality of Service level in infocommunication networks. The aim of the work is the development of a mathematical model of Fast ReRouting with the protection of the Quality of Service level by the bandwidth and probability of packet loss for data traffic. The following tasks are solved in the article: development and research of a fast rerouting flow-based model with the protection of the Quality of Service level of data traffic in the infocommunication network. The following methods are used: the graph theory, the teletraffic theory, the queuing theory, and mathematical programming methods. The following results were obtained: the fast rerouting flow-based model was developed and investigated, which, due to the introduced protection conditions on indicators of bandwidth and packet loss probability, allows providing the Quality of Service along both the primary and backup multipath. Conclusions: Within the framework of the proposed flow-based model, the fast rerouting technological task was formulated as an optimization problem with the constraints of the conditions of implementation of the multipath routing strategy, conditions of flow conservation, and conditions of protection of the link, node, and level of Quality of Service in terms of bandwidth and packet loss probability. The application of this solution contributes to the optimal use of the available network resource while providing the specified level of Quality of Service in terms of bandwidth and probability of packet loss along both the primary and backup routes in the case of a failure of the infocommunication network elements. The proposed flow-based model can be used as the basis of the algorithmic software of existing routers and/or controllers of Software-Defined Networks, which are responsible for the calculation of the primary and backup paths in the fast rerouting of data traffic sensitive to such Quality of Service indicators as bandwidth and packet loss probability.
