Home routing gateway virtualization: An overview on the architecture alternatives

This paper presents a novel concept in home and access network architectures based on the virtualization within the service provider network of the layer-3 home routing gateway functionality. This new paradigm aims to diminish service providers' capital and operational expenditures in home equipment associated to the deployment of services for residential customers, while easing the deployment of new services due to the layer-2 visibility of the home network from the access network. Several architecture designs for this home routing gateway virtualization are presented together with a qualitative comparison among them. Finally, a list of topics for further study in order to make this paradigm a feasible deployment has been elaborated.
