The enhanced method of calculating the probability of message compromising in a communication network when using overlapping routes with series-parallel and combined structure are considered. A number of numerical examples have been used to analyze the influence on message compromising of security parameters belonging to certain elements (links) and fragments of the network. It is shown that the proposed...
In this paper, in order to increase the scalability of the communication network, a three-level method of hierarchical coordination routing in multi-area network is proposed, which is based on the principle of goal coordination. The method is based on the decomposition representation of the flow-based routing model and it includes three levels of the calculation hierarchy: at the zero level, the routing...
The method of segment hierarchical coordination routing in multi-area network has been proposed. The method based on decomposed implementation of How-based model of inter-area routing and goal coordination principle. In this method on the lower level, there is the calculation of the routing variables, and on the upper level, there is the coordination of the solutions obtained from lower level for...
A flow-based model of fault-tolerant routing with path protection has been improved. In the course of the improvement, when the fault-tolerant routing problem was presented in optimization form, an optimality criterion has been formulated, which contains the conditions for path protection when it is possible to implement both single path and multipath routing strategies. The novelty of the proposed...
The tensor model of QoS-routing has been proposed, where accounting of the network state dynamics was performed. The QoS-routing problem has been reduced to solution of the optimization problem associated with differentiated maximization the probability of timely delivery of packet flows in the network having a different service priority.
The improvement of the scalability of routing decisions is quite relevant in modern telecommunication networks. In this regard, effective approach is associated with the implementation of hierarchical routing. This involves carrying out a structural and functional decomposition of the network, based on the introduction and supporting of multi-level routing decisions. However, the existing protocol...
The routing tensor model in the basis of interpolar paths and internal node pairs with the guarantees by the packet rate and end-to-end delay is presented. The research demonstrated that the guarantees is provided for all paths in realization of the routing tensor model. The use of specified coordinate system facilitates compliance with the requirements for the packet end-to-end delay, i.e. average...
Dynamic presentation of tensor model for multipath routing with QoS guarantees over the multiple parameters proposed. Expressions for different queuing systems modeling state of the network router interface used for representing the average packet delay as time-varying function. Conditions of ensuring QoS for the set of parameters as packet transmission rate and average delay obtained. The novelty...
Effective solution for scalability and productivity improvement in fault-tolerant routing using the flow-based model was proposed. In practice, the fault-tolerant routing based on reservation of network resources is usually associated with decrease in overall performance and scalability of protocol solutions. In this regard, in structure of the model introduced conditions that are responsible for...
