                 Virtual CPE Deployment Considerations
                    draft-pularikkal-virtual-cpe-02

Abstract

   Broadband Service Provider Industry has been gearing towards the
   adoption of Virtual CPE (vCPE) solutions.  The concept of vCPE is
   build around the idea that the physical CPE device at the customer
   premises can be simplified by moving some of the key feature
   functionalities from the physical CPE device to the Service Provider
   Network.  This document starts discussing the drivers behind vCPE
   adoption followed by Solution level requirements.  Two key
   Architecture models for vCPE, which can address the service provider
   and subscriber requirements, are covered in this reference document.
   Document also touches up on some of the key deployment
   considerations, which can influence the adoption of the vCPE
   architecture models.

1.  Introduction

   Broadband Service Providers are constantly looking for opportunities
   to generate additional revenue streams from their existing broadband
   infrastructure.  In order to achieve this, new value added services
   need to be created for the end customers.  Customer retention is
   another key focus area for broadband subscribers, where they have
