Explanation

Implementation Considerations for PPPoA Architecture The number of subscribers that will be serviced currently and in the future, as this affects the number of required PPP sessions. Whether the PPP sessions are being terminated at the service provider aggregation router or forwarded to other corporate gateways or Internet Service Providers (ISPs). Whether the service provider or the final service destination is providing the IP address to the subscriber's CPE. Whether the IP addresses provided are legal public or private. Is the CPE going to do NAT/PAT or will NAT be performed at the termination destination? Profiles of end subscribers, residential users, small office home office (SOHO) customers,and In the case of more than one user, whether all users need to reach the same final destination or service, or they all have different service destinations. Is the service provider providing any value added services like voice or video? Does the service provider require all subscribers to first go to a particular network before reaching a final destination? When subscribers use SSG, are they going to use passthrough services, PPP Terminated Aggregation (PTA), a mediation device, or How the service provider bills subscribers--based on a flat rate, per session usage, or services Deployment and provisioning of CPEs, DSLAMs and aggregation points of presence (POPs). The business model for the NAP. Does the model also include selling wholesale services like secure corporate access and value added services like voice and video? Are NAPs and NSPs the same The business model of the company. Is it comparable to an independent local exchange carrier (ILEC), a competitive local exchange carrier (CLEC) or an ISP? The types of applications the NSP will offer to the end subscriber. The anticipated upstream and downstream volume of data flow. Keeping these points in mind, we will discuss how the PPPoA architecture will fit and scale to different business models for service providers and how the providers can benefit using this
