Abstract

Admission control is required for satisfying QoS requirements in IP networks. Recently many researches report that end-point measurement-based admission control (EMBAC) is promising, because it does not request any signaling and functionality in routers, and thus is scalable. In this paper, we focus on an active end-point admission control and a passive end-point admission control. The former uses probe packets to measure network state. The latter does not use probe packets. We study probe packet interval in an active one, and a time required to measure packet loss rate in a passive one. We show that admission control performance depend on probe packet interval and monitoring time in active EMBAC. We also show that the optimal monitoring time is around 30sec in passive EMBAC.
