To guarantee strict Quality of Service (QoS) for real-time applications, we have previously proposed an output buffer control mechanism in IP routers, confirmed its effectiveness through simulations, and implemented a prototype. This mechanism can guarantee strict QoS within a single router. In this paper, we propose a control scheme of cooperation between IP routers equipped with this mechanism by using one of the signaling protocols. Our proposed scheme aims to stabilize End-to-End (E2E) flow delay within the target delay. In addition, our mechanism dynamically updates reserved resources between IP routers to improve E2E packet loss rate. We present an implemented design of our scheme and an empirical evaluation of the implementation. These results show quantitatively how our scheme improves the quality of video pictures.
