Abstract

This paper addresses the provisioning VPN services over shared network infrastructure with QoS guarantees (bandwidth and propagation delay), attempt to minimise the bandwidth reservation on the network. We present general MILP formulations based on the hose model and the pipe model. The reformulated MILP can be solved by standard MILP packages efficiently and scalably. The benchmark results show that the over-provisioning factor about 5 in bandwidth reservation for VPN can be reduced by the hose model, compared with the pipe model.
