    abstract =  {This document describes a declarative model for traffic steering policies in Distributed Data Center (DDC) scenarios. The policy model is a specific data model for traffic steering using VPN technology. It helps the service management in Simplified Use of Policy Abstractions (SUPA) to model the policy (a set of constraints and rules) that defines how a VPN service is monitored by bandwidth and managed during its lifecycle.},
