Abstract

The key feature of GMPLS is the provision of network resources and the automatic set-up of a path. And the mechanism of protection and restoration of a path is presented when network component fails. This paper suggests CR-LDP Static Detour Mechanism and Dynamic Detour Mechanism. CR-LDP Detours are a mechanism to set up detour paths automatically at every node to protect working path. Hence suggested mechanism performance is compared with existing mechanisms by computer simulation.

GMPLS는 신호 및 라우팅 기술을 기반으로 트래픽의 요구가 있을 때 동적으로 네트워크에서 경로를 설정하고 자원을 할당하는 기술이다. 또한 많은 양의 트래픽을 처리하는 특성상 네트워크의 실패(failure)가 일어났을 때 동적으로 트래픽을 보호하는 경로 보호 및 복구 메커니즘을 포함한다. 본 논문에서는 GMPLS의 신호 프로토콜 기술인 CR-LDP의 오브젝트를 확장하여 매 노드에서 자동적으로 우회 경로를 설정하여 주 경로를 보호 및 복구하기 위한 정적 우회 기법 및 동적 우회 기법을 제안하고 기존의 경로 보호 및 복구 기법과 성능을 비교 평가한다.
