The traditional virtual private network (VPN), which provides best-effort or static bandwidth allocation service, does not provide sufficient support for bursty Internet traffic.To support bursty traffic, a VPN provider can offer minimum throughput assurance (MTA) service to customers.MTA service provides higher throughput predictability than best-effort VPN service.Although there are many proposed network architectures for MTA service, certain parameters should be decided offline as part of the provisioning process.Determining adequate values of such parameters is necessary for quality of service control of bursty Internet traffic by providers.The difficulty in such provisioning is to meet the minimum throughput requirements in any active state matrices.We propose a provisioning algorithm that uses nonlinear programming for MTA service.We then numerically demonstrate the proposed algorithm and its performance.
