Abstract
In this paper, we propose methods for designing the Virtual Private Network (VPN) which guarantees a strict Quality of Service (QoS) over A TM networks. The required Quality of Service is a very strict Cell Loss Probability, and it is guaranteed by pro riding equivalent bandwidth which is computed so that the provided bandwidth is sufficient to guarantee that requirement. We consider two network architectures for constructing VPM, the customer pipe scheme and the Hose scheme, and we propose a method to compute the amount of the required bandwidth for the two schemes. Finally, we investigate the implication of the scheme via numerical experiments.
