We propose a hose bandwidth allocation method to achieve a minimum throughput assurance (MTA) service for the hose model. Although the hose model, which has been proposed as a novel VPN service model for provider provisioned virtual private networks (PPVPNs), has been proven to be effective for network resource efficiency and configuration complexity, there has been no consideration of a mechanism to assure quality of service (QoS) in the hose model. The basic idea of our method is to gather

We evaluate and clarify our method through computer simulation runs. The simulation results show that our method can achieve an MTA service in the hose model.
