A method and/or network configuration configured to enhance network performance using virtual system redundancy is disclosed. The network configuration, in one embodiment, includes a first packet core entity (“PCE”), routing cloud, and a second PCE. The first PCE, which includes a virtual backup module configured to facilitate virtual backup, actively provides network services to subscribers. The routing cloud provides network communication between network entities or PCEs across geographical distances. The second PCE, in one embodiment, includes a virtual smart core (“VSC”), wherein the VSC facilitates a redundancy instance for the first PCE. The first PCE and the second PCE may be separated with a long distance.
