Evaluating optical networks' business model

Günümüzde optik ağların iş modeli çeşitli katmanlardan oluşmaktadır: Son kullanıcılar, Servis Sağlayıcılar, Buluşma noktaları ve Taşıyıcılar. Bu katmanlar arasında işbirliğinin, uyumun çok alt seviyelerde olması ve herbirisinin kendi alanlarındaki teknolojik gelişmeleri diğer katmanları gözetmeden uygulamaları iş modelinde eksiklere ve hatalara sebep olmaktadır. Bugünkü modelin en başta gelen problemleri : 1) optimize edilmemiş topolojiler, 2) Düşük akıcılık, 3) Kaynak israfı, 4) Birlikte çalışma güçlüğü olarak sıralanabilir. Bu çalışmada bugünün iş modelinin eksik ve kusurları ile başedebilmek için yeni bir model sunulmuştur. Tümleşik Tarafsız Topoloji Eniyileştiriciler ağ katmanları arasında görev yapan ticari işlevi de bulunan yeni bir katmandır. Bu katman servis sağlayıcılar ve taşıyıcı kuruluşlar arasında, kullanılacak ağın kiralanmasından, üzerinde akan trafiğin görüntülenmesine ve topolojinin eniyileştirilmesine kadar görev yapar. Veri trafiğinin, hangi taşıyıcı kuruluşun hangi ağ parçası üzerinden gerçekleştireceğine bu katman karar verir ve sürdürür.

Today’s business model comprises of several layers: End users, Internet Service Providers (ISP), exchange points, and carriers. Arbitrary technological upgrades and absence of interaction in this layered business model, have led to critical system shortcomings. Foremost issues caused by this model are: 1.) unoptimized topology, 2.) low-liquidity, 3.) waste of resources, 4.) reduced interoperability. We introduce a new and novel concept for coping with the issues and shortcomings of today’s business model. Integrated Neutral Topology Optimizer (INTO) is an over all arbiter layer with commercial functionality. This layer operates with ISPs and carriers during leasing process and continually monitors the traffic to optimize the bandwidth usage. Inter-and-intra carrier connections are made and maintained according to the decisions of this layer.
