FLOW-BASED ROUTING MODEL WITH LOAD BALANCING UNDER NETWORK SECURITY PARAMETERS

Abstract

Background. In modern telecommunication networks, the functioning of network protocols is aimed at achieving a high level of Quality of Service and network security. Therefore, an urgent scientific and applied problem is the adaptation of routing solutions with load balancing to the requirements of network security. The novelty of the proposed model is the modification of the load balancing conditions, in which, in addition to the link bandwidth (Quality of Service indicator), the probability of its compromise (network security indicator) is also taken into account. The routing solutions obtained within the framework of the proposed model are aimed at reducing the overload of network links that have a high probability of compromise by switching traffic to more secure links.Objective. Developing the flow-based routing model with load balancing, which takes into account the parameters of network security.Methods. Analysis of all known publications on load balancing and network security. Synthesis of a load balancing flowbased routing model. Study of the influence of network security parameters of communication links on routing and load balancing processes.Results. A new condition for load balancing is proposed, which is a modification of the existing Traffic Engineering solution based on accounting the network security parameters - the probabilities of compromising communication links.Conclusions. In routing with load balancing, parameters of network security should be considered. Depending on the network state and user requirements, different models of network security parameters for load balancing processes can be used.
