Abstract: Configuration tool for virtual private network (VPN) topologies. In particular implementations, a method includes accessing a network topology configuration set comprising one or more route target groups (RTGs), wherein each RTG comprises a topology type identifier, one or more site identifiers, one or more role identifiers associated with each of the site identifiers, and one or more route target identifiers; generating one or more route target statements, based on the topology type identifier and role identifiers of one or more RTGs, defining the export or import of network layer reachability information between one or more routing nodes in a virtual private network (VPN) topology; and transmitting the one or more route target statements to one or more routing nodes.

Abstract: A capacity aware system that facilitates activation of a new service in a dynamic network is provided. The system calculates the available capacity of the network, at a given time, and determines if sufficient capacity is available for new service activation as per the SLA (Service Level Agreement) requirements. If SLA conditions are satisfied, the system can active a new service and update the network capacity, else, if the conditions are not satisfied the system can provide means to extend network capacity or reject the service. Thus, the system activates a new service only if the specified bandwidth is available and ensures that the SLA being promised to a customer is met.
