Research of Secure Routing with Load Balancing and Compromise Probability Behavior Account

The paper investigates secure routing with load balancing and considers compromise probability behavior. Within the framework of the study, the classical flow-based model based on load balancing according to Traffic Engineering concept was improved and supplemented with conditions that allow considering the network security parameters. In this way it was obtained the secure traffic engineering routing model, the novelty of which lies in the modified conditions of load balancing considering such network characteristics as topology, features of the traffic transmitted, as well as links bandwidth and probabilities of their compromising. The use of such a model makes it possible to reduce the overload of network links with a high value of compromise probability, while more traffic will be transmitted over secure links without causing overload. The specific functional dependence of weighting coefficients on the link compromise probability have been used during obtaining the secure-based routing solutions.
