초록

본 논문에서 광 네트워크에서 광 버스트 스위칭(Optical Burst Switching, OBS)과 광 회선 스위칭 (Optical Circuit Switching, OCS) 기술의 장점을 동시에 가지는 새로운 광 hybrid 스위칭(Optical Hybrid Switching) 시스템을 제안한다. 이 시스템은 들어오는 IP 트래픽을 hybrid 스위칭을 위해 짧은(short-lived) 흐름과 긴(long-lived) 흐름 구분한다. 성능 분석을 위하여 시스템을 Markovian 환경에서 단일 서버 큐로서 모델링 한다. 버스트 생성 프로세스는 two-state Markov Modulated Poisson Process (MMPP)를 따른다고 가정하고 서비스 율은 동시에 발생하는 OCS 세션의 수에 따라 변한다. OBS 버스트에 대한 평균 지연 및 큐 사이즈의 결과를 보인다.

In this paper, we propose a new optical hybrid switching system that takes advantage of both Optical Burst Switching (OBS) and Optical Circuit Switching (OCS) technologies. This system classifies incoming IP traffic flows into short-lived and long-lived flows for hybrid switching. For performance analysis, we model the system as a single server queue in a Markovian environment. The burst generation process is assumed to follow a two-state Markov Modulated Poisson Process (MMPP), and the service rate fluctuates based on the number of concurrent OCS sessions. Results of the mean delay and queue size for OBS bursts are derived.
