On the J-series device, PPPoE establishes a point-to-point connection between the client (J-series device) and the server, also called an access concentrator. Multiple hosts can be connected to the device, and their data can be authenticated, encrypted, and compressed before the traffic is sent to the PPPoE session on the J-series device's Fast Ethernet, Gigabit Ethernet, ATM-over-ADSL, or ATM-over-SHDSL interface. PPPoE is easy to configure and allows services to be managed on a per user basis rather than on a per site basis.
