چکیده
요 약 IP 망을 활용한 VPN(Virtual Private Network)에서의 QoS 보장 및 광대역 서비스 제공에 대한 해결 방안으로 차세대 광 인터넷을 통한 OVPN(Optical VPN) 기술이 제시되고 있다. 차세대 광 인터넷의 구현 이 IP/GMPLS(Generalized Multi-Protocol Label Switching) over DWDM(Dense Wavelength Division Multiplexing) 프로토콜 프레임워크로 표준화되고 있는 현실에 비추어 볼 때, IP/GMPLS over DWDM 백본망을 통한 OVPN 은 차세대 가상사설망으로써 멀티미디어 서비스 제공을 위한 최적의 방안이 다. 이러한 멀티미디어 서비스 제공을 위한 OVPN 에서는 최적의 Optical-LSP(Label Switched Path)의 설립이 요구되고 있다. 따라서 본 논문에서는 차등화된 광 QoS 서비스를 제공하는 OVPN 의 모델을 제시 하고, 네트워크 이용률의 향상을 위한 미래의 잠재적인 연결 요구에 대해 간섭을 최소화하면서 경로를 설 정하는 MW-MIPR 라우팅 알고리즘을 제안한다. 그리고 기존의 알고리즘들과의 성능 비교를 통해 제안 된 알고리즘의 효율성을 검증하였다.

متن کاملA Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...

In this paper, a new traffic engineering-capable routing and wavelength assignment scheme is proposed to efficiently handle LSP and lightpath setup requests with different QoS requirements on modern multi-layer (fully optical core and time-division multiplexed edge) transport networks. The objectives of the proposed algorithm are to minimize the rejection probability by maximizing the network l...
متن کاملA minimum interference routing algorithm with reduced computational complexity
Minimum Interference Routing algorithms are designed to reduce rejections of future requests for the establishment of Label Switched Paths (LSPs) but make no assumption about specific patterns of arrival request. This paper introduces a novel minimum interference routing algorithm, Light Minimum Interference Routing (LMIR), which is based on a new approach to the identification of critical link...
