What is BGP

Aviation telecommunications is one of the main means of providing guidance to civil aviation and air traffic control. Proper organization of communication is one of the main conditions for ensuring the safety and regularity of aircraft operations as well as the production activities of enterprises and civil aviation organizations. The new networks will focus on significantly improving the quality of service. The basis for their construction will form SDN networks. Therefore, the chapter analyzed the advantages and disadvantages of two SDN implementing methods. It was developed the mathematical method to assess their complex effectiveness, which considers QoS requirements of implementing service through special weights for scalability, performance, and packet delay. There were simulations of overlay networks by using soft switches to verify the adequacy of the proposed method. The results showed that the use of SDN networks more efficiently by using IP networks for large volumes of traffic and with a large amount of network equipment.
