Why would it be used?

PPPoE is used to allow Internet Service Providers (ISPs) the use of their existing Radius authentication systems from their Dial-Up service on a Broadband / Ethernet based service. Dial-Up is PPP, most broadband connections are Ethernet, hence Point to Point Protocol over Ethernet. It also allows for ISPs to resell the same line multiple times. IE: Rated services, Broadband specific content (movies, etc.), metered services, etc.

As an ISP why would we use PPPoE?
The items that need to be remembered are the advantages that PPPoE offers to a provider that PPPoA does not: Brand Management, Revenue Generating Options and Decreased Call Center Support.

PPPoE offers the luxury of being able to easily set up multiple models that allow a provider to resell the same line to one customer multiple times for additional services and/or create multiple options to give more services to choose from to increase their customer base.

Sell the same line multiple times with multiple Services
• Basic Internet Service – This is the basic flat service, that your customer would be using, you could offer multiple services on top of this for additional monthly revenue, for example:
• Movie Server – Partner with a content provider and set up a movie server that you could sell a userid IP and password to access the server and charge by the month, or by the movie etc
• Streaming Radio Server - Partner with a content provider and set up a Streaming Radio (music) server that you could sell a userid IP and password to access the server and charge by the month
• Video Game Server - Partner with a content provider and set up a Video Game server that you could sell a userid IP and password to access the server and host video games tournaments and charge by the month
The above 3 examples are all hosted locally and only customers on your network with a userid and password can access them so all the traffic is local creating no additional bandwidth charges to the provider.
• Speed Options – instead of supporting home network offer multiple userids on the same line that each get their own dedicated speeds, this would be set up via the radius attributes for each userid so they would each have a set speed assigned to that userid. Charge each the flat basic internet service fee
• Rated Access – provide a userid for children which has G rated access to the Internet only and is filtered at the Provider end so children can’t shut it off. Charge the account holder a reduced monthly fee for this service (or offer it as a value add for great marketing)

More Service Options
• Time Packages – Customer may only want 5 hours broadband hours per month due to travel etc so offer different hourly packages at discounted rates and offer an unlimited package for the average user who does not want to worry about hours
• Data amount Packages – Bandwidth is expensive, charge users for the bandwidth they use so offer different monthly data transfer packages at discounted rates with a charge for overage and offer an unlimited package for the average user who does not want to worry about hours (done in much of the Canadian Market, as well as Australia etc)
• Multiple Speed Packages – Provision line once for full speed then create speed packages and throttle the speed by userid (both upload and download) in the radius server instead of a truck roll to the hardware to re-provision the line for a new speed package
• Rated Access Accounts– Set up packages which has rated access to the Internet only and are filtered at the Provider end so customers can’t bypass them. Offer G rate, PG, AA, R, and X packages each with a monthly price associated
• Personal IP – for that user that needs a static IP, set up radius to give that person the same IP on every login, charge a larger monthly price for this package (or offer it as a value add for marketing opportunities)

Ease of Sign up / Advertising
• Use of market existing up sign up software to sign up and provision broadband account attributes with out need of a truck roll if line is currently provisioned for service, if line is not provisioned you could still use the sign up software but it could not avoid you a truck roll if equipment has to be turned on or installed, but if line was already provisioned all above mentioned packages could be advertised in sign up software and provisioned automatically with sign up software
• Dynamic Service Selection (to advertise multiple services without advertising dollars). With PPPoE Broadband Management Servers you can set up the servers (or services available) and a PPPoE client side application can see these services and advertise them to the end user at no cost to the provider, making for free advertising.

Wholesale Market
• Forget call center costs etc, whole sale your access to other providers and charge them a flat fee per month per customer that they sign up and support
