Son yıllarda internet kullanımının katlanarak artması, kullanıcılara sunulan internet uygulamalarındaki çeşitlilik ve bunların hızlı gelişimi, çok büyük oranlarda bantgenişliği talebini ortaya çıkarmıştır. Özellikle bire-çok bağıntı ya da çoktan-çok bağıntı iletişimi yapısında olan çoğa gönderim uygulamalarını temel alan yüksek bantgenişliği gerektiren uygulamalardan video konferans, uzaktan interaktif eğitim gibi örnekler optik ağlarda Dalgaboyu Bölümlemeli Çoğullama-DBÇ (Wavelength Division MultiplexingWDM) teknolojisi sayesinde kullanıcılara kolaylıkla ulaştırılmaktadır. Bu çalışmada Optik Çoğuşma Anahtarlama (Optical Burst Switching-OBS) ağlarda çoğa gönderimi sağlayabilmek için Önceden Hesaplanan Yol Çoğa Gönderim (Precalculated Path Multicast-PPM) isimli yeni bir protokol sunulmuştur. Protokol yapısı ve işleyişi durum diyagramları kullanılarak açıklanmıştır

Optical Burst Switching (OBS) and Multicasting Over Wavelength Division Multiplexing (WDM)

Öz

The great increase of internet utilization, the variety and quick developments of internet applications that are proposed to the users, reveals the demand of great amounts of bandwidth requirment. Especially, one to many or many to many transmission type, multicast based and high bandwidth needed applications like video conference and distance interactive education are transmitted to the users easily by the Wavelength Division Multiplexing (WDM) technology in OBS (Optical Burst Switching) networks. In this study, to provide multicasting in OBS networks a new protocol which is named as Precalculated Path Multicast (PPM) is presented. Protocol architecture and mechanism is explained by state diagrams
