Abstract

The demands of network users emphasize the improvement and guarantee of service quality as well as the increment of bandwidth. As a result, high performance and additional new functions are important features to build network equipments, especially and edge router. For this structure, network processors with high performance and flexibility are considered as a main part of a packet forwarding module. In this paper, we design and edge MPLS router with a network processor, which supports high performance and multi-functionalities and examine its advantage and limitation.

인터넷이 급성장하면서 망 사용자들은 대역폭의 증가라는 양적인 측면 외에도 서비스 품질의 개선과 보장이라는 질적인 측면까지 요구하게 되었다. 점점 더 망의 기능성이 강조됨에 따라 망 장비의 성능과 기능도 중요하게 여겨지고 있는데, 특히 에지 라우터는 고성능, 다기능, 유연성이 모두 요구되는 시스템이다. 이러한 특성의 시스템 설계를 위해 최근 고려되고 있는 방법이 네트워크 프로세서를 사용하는 것이다. 본 논문에서는 ASIC의 고성능과 소프트웨어 기반의 유연성을 모두 제공하는 네트워크 프로세서를 사용하여 에지 급의 MPLS 라우터를 개발하고, 그 결과를 기반으로 네트워크 프로세서의 향후 적용가능성을 살펴본다.
