Abstract

The supply expansion of 5G services and personal smart devices has caused the sharp increase of data traffic and the demand of various services. Again, these facts have resulted in the huge demand of network bandwidth. However, existing network technologies using electronic signal have reached the limit to accommodate the demand. Therefore, in order to accept this request, optical internet has been studied actively. However, optical internet still has a lot of problems to solve, and among these barriers a very urgent issue is to develop QoS technologies. Hence, in order to achieve service differentiation between classes in optical internet, especially in OBS network, a new QoS method automatically tuning the size of data bursts is proposed in this article. Especially, the algorithm suggested in this article is based on fiber delay line.

5G 서비스와 개인용 스마트 기기의 보급 확대는 트래픽의 폭증과 다양한 서비스에 대한 수요로 이어졌다. 이런 사실은 다시 네트워크 대역폭에 대한 거대한 수요로 이어졌다. 그러나, 전기 신호를 사용하는 기존의 네트워크 기술들은 이러한 수요를 감당하는 데 한계에 다다랐다. 이에 이러한 요구를 수용하기 위해, 광 인터넷이 활발하게 연구되고 있다. 그러나, 광 인터넷도 여전히 해결해야 할 많은 문제점을 가지고 있고, 이러한 문제점 중에서 가장 시급한 문제는 QoS 기술을 개발하는 것이다. 그러므로 광 인터넷-특히 OBS 네트워크-에서 클래스간 서비스 차별화를 달성하기 위해, 데이터 버스트의 크기를 동적으로 제어하는 새로운 QoS 기법이 본 논문에서 제안된다. 특히 본 논문에서는 광 지연 라인을 기반으로 하는 알고리즘을 제안한다.
