Performance evaluations of a link state update mechanism considering traffic variation

트래픽 변화를 고려한 링크 상태 업데이트 알고리즘의 성능 분석

Routers determine routing path considering network topology and link state information for providing QoS (quality of service) guarantee. Therefore, it is important that routers know link state information to calculate routing path. However, if routers generate link state update messages inordinately, their router performance are reduced due to the process of link state update messages. On the other side, in case that link state information is not updated appropriately, route setup requests can be rejected even though there exist routes. In this paper, we propose an algorithm to improve router performance and evaluate the proposed algorithm performance compare with conventional algorithm by simulations.
