Abstract:
A method, apparatus and article of manufacture for building next generation improved regional virtual private networks over the Internet. The method comprises of building two layers on top of the public infrastructure (): a network abstraction layer (NAL) () and a network virtualization layer (NVL) (): the NVL () is built on top of the NAL (). The NVL () consists in Group Domain of Interpretation (GDOI) domain deployments on virtualized hardware aggregators over a NAL (). The latter consists in point-to-multipoint Generic Routing Encapsulation (GRE) networks over the Internet (). Both the NVL () and NAL () can be deployed using advanced unattended provisioning methodology.
