Measurement Based Characterization and Provisioning of IP VPNs
Overview Virtual Private Networks provide secure and reliable communication between customer sites. With increase in number and size of VPNs, providers need efficient provisioning techniques that adapt to customer demand by leveraging a good understanding of VPN properties. This paper analyze two important properties of VPNs that impact provisioning - structure of Customer End-point (CE) interactions and temporal characteristics of CE-CE traffic. The paper deduces these properties by computing traffic matrices from SNMP measurements. It was found that existing traffic matrix estimation techniques are not readily applicable to the VPN scenario due to the scale of the problem and limited measurement information. It begin by formulating a scalable technique that makes the most out of existing measurement information and provides good estimates for common VPN structures.
