Abstract

In this paper, we implement a diffserv-capable router on the linux system and evaluate its performance. The router supports the packet marking for the input finks that is different from the previous implementation. The edge diffserv-capable router can guarantee the performance of each class, even in a congested condition. We compare the performance of the diffserv-capable router with that of the normal router in terms of PDBs (per domain behaviors), which are defined with traffic conditioning rules and PHBs (per hop behaviors).

본 논문에서는 차등화서비스모델(differentiated service model)을 지원하는 라우터를 리눅스상에서 구현하였다. 구현한 라우터는 기존 구현과 달리 입력 단에서부터 패킷마킹이 가능하도록 하였다. 입력 단에서부터 패킷마킹이 가능한 에지 라우터는 네트워크 병목현상이 발생한 경우에도 각 클래스간 독립적으로 서비스를 보장해 줄 수 있다. 구현된 라우터는 기존 라우터와의 성능비교를 하였으며, 망의 입력 라우터의 트래픽 조절 규칙과 망 내외 PHB(per hop behavior) 특성을 규격화하여 정의되는 PDB(perdomain behavior) 실험을 통하여 성능을 측정하며 검증하였다.
