What is a PPPoE Termination unit?
PPPoE Termination units (also known as Access Concentrators (AC), Broadband
Management Servers (BMS), and Broadband Residential Access Servers (BRAS))
answer the PPPoE request coming from a client site PPPoE application
(such as WinPoET).
After the PPPoE process (Involving a PADI, PADO, PADR and PADS) there
is PPP negotiation and Radius authentication. Once all this is complete
the subscriber can now surf the Internet through their service providers
What PPPoE Termination Server should we use?

best suit your needs. Typically a solution like ServPoET

Why Recommend ServPoET
from Fine Point
Today's service providers and carriers are very limited by the expenses
of expanding their broadband networks to support new service offerings
and reducing costs. These challenges can be met by simply offloading
the resource intensive PPP over Ethernet (PPPoE) processing from the
Edge Routers and Access Concentrators. Many of these routers lose about
10 fold their performance the minute PPPoE is enabled on those devices.
This limits the network from it's original capacity, let's say 10,000
subscribers, to about 1,000. With the cost of those devices it's just
not feasible to build out a network to accept more subscribers. With
a product like ServPoET the cost per subscriber can go from 12 dollars
per user on a router to as low as 3 dollars per user with ServPoET.
Broadband Management Server (BMS) platform provides the industry-leading
family of PPPoE subscriber management products that offload and terminate
PPPoE sessions for all types of broadband service at nearly 1/4 the
cost and 3x the performance. The ServPoET
BMS™ platform offers carriers and service providers worldwide
a solution for aggregating and managing broadband PPPoE subscribers
and value-added services.
Are their cheap PPPoE Access Concentrators on the market?
There are inexpensive options on the market. Our test findings have
found some interesting information though on the two inexpensive options
on the market though. Using some of these solutions for PPPoE can cause
a problem depending on the amount of subscriber sessions it's terminating,
as well as the original RP-PPPoE (which is in StarOS as well as general
Linux Distros). Both devices are not cut out for commercial applications
and die out on CPU quite quickly when processing bandwidth due to the
data processing being done in user space.
For example if you had 100 customers in one of these devices with gigabit
ethernet interfaces (a tried and tested example) the throughput is cut
to less than 400 mbps, and this is with no other protocols or features
enabled on the OS, literally just PPPoE. With 250 subscribers the throughput
drops to under 300 mbps, before 100 CPU utilization and this is on a
2.4 GHz server.
Now I realize this all depends on the size of your network and if you
are doing centralized termination or termination at the access point,
but with centralized PPPoE termination and any other features on the
unit most real world experience is major issues at more than 100 subscribers.
What can I do with a PPPoE Server?
You could offer tiered levels of service.
Different levels of Speed can be set by userid in a product like ServPoET.
Maybe you want to charge your users by the hour or minute You could
also charge your users by the "byte"
Some PPPoE Termination Systems, like ServPoET,
offer the ability to roll out Dynamic Service Selection. This option
allows you to set up different services and allows customers the ability
to log in to them if you've set that up in your profile. With software
for example the customer can be shown that services are available for
them to access (of course you'd want to charge them for use of these
