A public–private partnership (PPP, 3P, or P3) is a long-term arrangement between a government and private sector institutions. [1] [2] Typically, it involves private capital financing government projects and services up-front, and then drawing revenues from taxpayers and/or users for profit over the course of the PPP contract. [3]
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.
Public–private partnerships (PPP or P3) are cooperative arrangements between two or more public and private sectors, typically of a long-term nature. [1] In the United States , they mostly took the form of toll roads concessions , community post offices and urban renewal projects. [ 2 ]
PPTP uses a TCP control channel and a Generic Routing Encapsulation tunnel to encapsulate PPP packets. Many modern VPNs use various forms of UDP for this same functionality. The PPTP specification does not describe encryption or authentication features and relies on the Point-to-Point Protocol being tunneled to implement any and all security ...
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 ...
Build–operate–transfer (BOT) or build–own–operate–transfer (BOOT) is a form of project delivery method, usually for large-scale infrastructure projects, wherein a private entity receives a concession from the public sector (or the private sector on rare occasions) to finance, design, construct, own, and operate a facility stated in the concession contract.
Sign at the entrance of the Regina Wastewater Treatment Plant. PPP Canada's definition of Public-private partnership was "a long-term performance-based approach to procuring public infrastructure where the private sector assumes a major share of the risks in terms of financing and construction and ensuring effective performance of the infrastructure, from design and planning, to long-term ...
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.
