Abstract: An example method for topology aware provisioning in a software-defined network environment is provided and includes receiving, at a provider edge device (PE), access network topology information associated with a customer edge device in a network environment, synthesizing the access network topology information and a local router information associated with the PE into a topology message, and publishing the topology message to a central controller in the network environment. The synthesizing can include aggregating the access network topology information and the local router information, modeling the aggregated information in a representation-independent format and encoding the representation-independent formatted aggregated information in standardized machine-parsable format.
