Though PPP/PPPoA is optional, it is a very logical choice for establishing individual
Internet access for each customer over an ATM-based network.
The motive is to use PPP's features
(see the PPP overview, which you can link to from the Stack page).
PPP fits naturally over ATM since both are
connection oriented.
PPPoA encapsulates PPP's packets using the method defined in RFC 2364.
With this method the customer is always connected
after the establishment of the virual circuit. |
