Abstract

A universal access solution is described which includes an Access Unit (AU) that utilizes Virtual Network Functions (VNFs) executed on a server coupled to a plurality of pluggable modules which provide line-side and client-side connectivity. The VNFs enable various different higher-level applications to provide virtualization to end customers, and the pluggable modules allow any type of technology or topology as an application requires. The AUs can be used as a next-generation access device for enterprises, residential, etc. The AUs can support GPON, ADSL, VDSL, and the like. The AUs can also provide dual functionality to service providers, namely a unified access solution as well as forming a distributed data center, expanding the data center from the Central Office (CO) into the access network.

UNIFIED ACCESS SOLUTION USING NETWORK FUNCTIONS VIRTUALIZATION PROVIDING END CUSTOMER ACCESS AND DISTRIBUTED DATA CENTER FUNCTIONALITY

ABSTRACT

[0001]               A universal access solution is described which includes an Access Unit (AU) that utilizes Virtual Network Functions (VNFs) executed on a server coupled to a plurality of pluggable modules which provide line-side and client-side connectivity. The VNFs enable various different higher-level applications to provide virtualization to end customers, and the pluggable modules allow any type of technology or topology as an application requires. The AUs can be used as a next-generation access device for enterprises, residential, etc. The AUs can support GPON, ADSL, VDSL, and the like. The AUs can also provide dual functionality to service providers, namely a unified access solution as well as forming a distributed data center, expanding the data center from the Central Office (CO) into the access network.

BACKGROUND

[0002]               Conventionally, access solutions utilize special build access technology for enterprises, Single Owner Home Office (SOHO), residential, Outside Plant (OSP), Central Office (CO), etc.  Network Functions Virtualization (NFV) technology is nascent in the access field today, but it is an area of wide and growing interest by service providers.  By combining the two technologies, a solution can be formed that provides higher functionality with higher value and the ability to utilize the technology 100% of the time for revenue generating activities.  Conventional access technology, although perhaps less expensive than general server technology, is limited in functionality and the ability to add new features, i.e., it has only a single purpose.
