Managing highly dynamic services using extended temporal network information models

Dynamic virtual private networks (DVPN) are virtual private networks with a high degree of change in terms of membership, implying the necessity for fast reconfiguration and provisioning. Their management requires a time and evolution aware network information model capable to capture both temporal and aggregate information. Such a model is proposed in this paper. The resulting model is used in the framework of a programmable and active network based management platform associated with a DVPN service. The particular DVPN service is used in the context of live TV broadcast to the subscribed residential users
