To provide a PPPoE connection, each PPP session must learn the Ethernet address of the remote peer and establish a unique session identifier during the PPPoE discovery and session stages. Essentially, it’s more akin to how modems establish a connection with each other than how Internet works.

Point-to-Point Protocol. The PPPoE client is in built in the modem and allocated by BRAS … PPP is a non-proprietary protocol defined by IETF RFC 1661 which can be used on point to point links. The HDLC and PPP are the crucial data link layer protocols used in WAN (wide area network) where the HDLC can also be implemented with PPP …
PPPoE - Point to Point Protocol over Ethernet is basically a way to connect two devices.

Some internet service providers use Point to Point Protocol over Ethernet to manage the connections of individual subscribers.

PPP is a protocol which has three underlying components: An encapsulation protocol such as HDLC , Ethernet or ATM All mainstream broadband routers support PPPoE as an internet connection mode.




Perhaps something fiber-related that makes PPP vastly superior to Ethernet for this scenario. – dlyk1988 Sep 8 '13 at 23:46 Nah, I think PPP is just going to make things worse. The major difference between HDLC and PPP is that HDLC is the bit oriented protocol, while PPP is the character-oriented protocol. PPPoE, short for Point-to-Point Protocol over Ethernet, is an Ethernet encapsulation of the Point to Point Protocol that is commonly used with dial-up connections. Throughout the documentation for both protocols, points are referred to as nodes, computers, or hosts.

Somewhat more specifically speaking, IPoE is often used in comparison to PPPoE when discussing how services such as residential broadband are delivered to the end user. Like the two other WAN protocols mentioned in this article, HDLC is a Layer 2 protocol (see OSI Model for more information on Layers).

Point To Point Protocol (PPP) and Point To Point Protocol over Ethernet (PPPoE) are network protocols that allow data communication between two network entities or points.

computers, smartphones Gigabit Ethernet switch and etc.)

This allows the modem to be a part of the network that multiple users can utilize instead of being connected directly to the computer.

In this mode the modem works as router and the PPPoE session terminates on WAN port of router.

DHCP is a way for a network to allocate unique IP addresses to the devices (i.e.

HDLC stands for High-Level Data Link Control protocol. PPPoE vs DHCP: What Is PPPoE?

There really isn’t a PPPoE IP address.
