Quality-of-Service Based Network Traffic Management in Air Traffic Management System’s Core Network (Air-SDN)

Öz

Air Traffic Management (ATM) Systems provide managing all flights in the airspace including commercial air transporting. Because of this system contains real-time, consistent and critical data, the network traffic which occurs in the core network of this system should be managed to satisfy these parameters; in other terms, a quality of service (QoS) approach should be applied to this network structure. Air-SDN method, which is proposed in this paper makes enable to manage network traffic fast and reliable within ATM System’s core network using a specified quality of service (QoS) manner in Software Defined Networking (SDN) concept. Air-SDN method is emulated in a test-bed and it has been observed that this method provides performance gain as 153% for TCP transport protocol, 63% for UDP and Burst-UDP transport protocols.

Hava Trafik Yönetim Sistemleri Çekirdek Ağlarında Servis Kalitesi Temelli Ağ Trafik Yönetimi (Air-SDN)

Öz

Hava Trafik Yönetim (ATM) sistemleri, ticari hava taşımacılığının yanı sıra hava sahasında gerçekleşen tüm uçuşların yönetimini sağlar. Bu sistemin gerçek zamanlı, sürekli ve kritik veri barındırması nedeniyle, sistemin çekirdek ağında gerçekleşen ağ trafiğinin bu parametrelere cevap verebilecek şekilde yönetilmesi, başka bir ifade ile bu ağ yapısında belirli bir servis kalitesi (QoS) yaklaşımının uygulanması gerekmektedir. Bu çalışmada önerilen Air-SDN yöntemi, ATM sistemlerindeki çekirdek ağlarda Yazılım Tanımlı Ağ (SDN) konsepti çerçevesi içerisinde belirli bir servis kalitesi (QoS) yöntemi uygulayarak ağ trafiğinin hızlı ve güvenli yönetilmesine olanak tanımaktadır. Air-SDN yöntemi bir test ortamında emüle edilmiş ve önerilen yöntemin, TCP taşıma protokolü ile %153, UDP ve Burst-UDP taşıma protokolleri için de %63 oranında veri çıkış hacmi parametresinde performans artışı sağladığı gözlenmiştir.
