Virtual Private Networks (VPNs) are overlay networks established on top of a public network backbone with the goal of providing a low cost but secure network solution. The allocation of bandwidth for VPN tunnels to meet the requirements specified by customers is an important traffic engineering research issue. This paper addresses the general problem of(More)
Virtual private network (VPN) design according to a tree topology has been the subject of numerous research papers. Two workload models are commonly used to allow VPN clients to specify the communication capacity they need, the hose and the pipe workload models. As opposed to the pipe model, where bandwidth needs between every pair of endpoints must be(More)
