At the present day service providers are faced with the growing complexity of telecommunications networks, growth in the volume of data transmitted and increasing the number of devices connected to the operating networks. Active distribution of network devices makes communications providers find opportunities to rapidly reduce the current costs with continuous introduction of new services and technologies. The problem of optimizing the structure of the network by the criterion of minimum cost in the shortest possible time and in real time, as well as the task of finding the optimal routes has previously constructed a network is arises. Coordinated work of service providers, combining expertise in building and managing IP-networks, sharing opportunities for the development and delivery of new customer-oriented services can be particularly advantageous in the work of operators will reduce cost of providing telecommunications services. Collaboration of providers create new revenue streams, improve the quality and accelerate the development of telecommunications services, increase the data rate and the number of involved customers, as well as create innovative networking technology.
In connection with this, the development of adaptive routing algorithms in corporate networks of multiple service providers with different covering areas of subscribers are the actual direction.
Mathematical model and adaptive routing algorithm which reduce the complexity of building a routing table in the course of dynamic changes of the load on the communication lines, as well as produce a complete recalculation of the routing tables are offered in article.
Software of adaptive routing processes modeling, confirming the validity of the proposed model and adaptive routing algorithm in corporate networks of multiple service providers with different covering areas of subscribers is developed. As part of the validation test it was carried out numerical calculations graph models of corporate networks, consisting of 10, 50 and 100 communication nodes in the presence of two service providers in the network. The research of the adaptive routing algorithm show its effectiveness in comparison with existing analogues by constructing an optimal routes data and exclusion of their cost — the cost of unused channels and communication nodes.
