PPP is a layered protocol that has three components: [4] An encapsulation component that is used to transmit datagrams over the specified physical layer. A Link Control Protocol (LCP) to establish, configure, and test the link as well as negotiate settings, options and the use of features.
It also supports the encapsulation types: VC-MUX and LLC - see RFC 2364. If it is used as the connection encapsulation method on an ATM based network it can reduce overhead significantly compared with PPPoEoA – by between 0 and ~3.125% for long packets, depending on the packet length and also on the choices of header options in PPPoEoA ...
The Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol for encapsulating Point-to-Point Protocol (PPP) frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet.

There is no widely accepted definition of what a PPP unit is. The World Bank defines a PPP Unit as an organization that “promotes or improves PPPs. It may manage the number and quality of PPPs by trying to attract more PPPs or trying to ensure that the PPPs meet specific quality criteria such as affordability, value for money, and appropriate risk transfer.” [2] Heather Whiteside describes ...

Public–private partnership (PPP or P3) in Canada is a form of alternative service delivery that involves a formal, collaborative arrangement between the public and private sectors, typically of a long-term nature.
