A resource management mechanism for hose model based VPN QoS provisioning

Abstract

Among the resource management mechanisms for the hose based Virtual Private Network(VPN) Quality of Service(QoS), VPN-specific state provisioning allows the service provider to obtain highest resource multiplexing gains. However, users of a VPN may experience unfair usage of resources among themselves since the reserved resources of a VPN are shared by the VPN users in a similar way that the traditional LAN bandwidth is shared by the attached hosts. In this paper, we propose a resource reservation protocol and a traffic service mechanism, which not only enable dynamic and automatic resource reservation according to the VPN-specific state provisioning algorithm, but also enforce the fair usage of reserved resources among the users of a VPN in case of congestion. © Springer-Verlag Berlin Heidelberg 2006.
