Abstract

Over for the past 10 years, the increase in geometric progression for the internet traffic, has allowed the IP protocol framework to be the most important network technology. In addition, the internet service is being developed as a service mode differentiated, aiming to support the new-mode real-time multimedia services such as internet phone, video conference, cyber reality, and internet game, focusing on offering a latest service. These days, aiming to solve the need for broad bandwidth along with guaranteeing QoS, the WDM technology of offering multiple gigabit wavelengths is emerging as the core technology of next-generation optical internet backbone network. In the next-generation optical internet backbone network based on WDM, the QoS framework is one of fore subjects aiming to offer a service of guaranteeing QoS This study analyzes the requirements of performance related to QoS framework in IP Subnet and in WDM optical backbone network, and suggests optical QoS service framework differentiated. in order to guarantee end-to-end QoS through the next-generation optical internet backbone network, using GMPLS control protocol.

지난 10년간 인터넷 트래픽의 기하급수적인 증가는 IP 프로토콜 프레임워크를 가장 중요한 네트워크 기술로 만들었다. 더욱이, 인터넷 서비스는 최선형 서비스 제공 위주에서 인터넷 폰, 비디오 컨퍼런스, 가상 현실, 인터넷 게임과 같은 새로운 형태의 실시간 멀티미디어 서비스들을 QoS보장과 함께 지원하기 위해서 차등화된 서비스 형태로 발전하고 있다. 최근, QoS 보장과 함께 광 대역폭의 요구 해결을 위해 다중 기가비트 파장을 제공하는 WDM 기술이 차세대 광 인터넷 백본망의 중심 기술로 부상하고 있다. WDM 기반의 차세대 광 인터넷 백본망에서 QoS 프레임워크는 QoS 보장형 서비스를 제공하기 위한 핵심 과제 중의 하나이다. 본 논문에서는 IP 서브망과 WDM 광 백본망에서 QoS 프레임워크와 관련된 성능 요구사항을 분석하고, GMPLS 제어 프로토콜을 이용하여 차세대 광 인터넷 백본망을 통해 종단간 QoS를 보장하기 위한 차등화된 광 QoS 서비스 프레임워크를 제안한다.
