applications or device drivers developed by developers. Because Windows CE-based operating systems have similar user interfaces as Microsoft Windows operating systems, they are favored by many end users and developers. Currently, WindowsCE has been widely used in mobile phones, palm computers, personal digital assistants, quick translation, electronic dictionaries, and other portable devices.
For a long time, WindowsCE devices also need to be equipped with a host based on Windows9x/2000/NT for
Android, which have clients connected to PPTP. Of course there is another reason, is that we buy VPS based on Xen PV technology, can build PPTP. This is actually the result, the original to buy based on Xen PV rather than OpenVZ, is because of the plan to build PPTP services. Btw,xen PV is a kind of semi virtualization technology that cannot run Windows, but is said to be more efficient than a fully virtualized Xen HVM run Linux.

Because SDH rings provide point-to-point connections between routes, IP packets must be mapped to point-to-point links. The most common technology is IETF's Point-to-Point Protocol (PPP) encapsulation. IP over SDH is also called Packet over SDHPOS) technology.

Application of pppoe in Broadband Access Network
In recent years, network data services have developed rapidly and broadband users have experienced explosive growth. Operators are using multiple access methods, such as XDSL, lan, HFC, and wireless, to build an operational, manageable, and profitable broadband network, pppoe is one of the following authentication technologies, with great interest in how to effectively manage users.

Background:It should be very easy to build a pptp vpn Server. However, many of my friends have turned to me for help after reading some articles and have taken many detours.Therefore, I think it is necessary to write an article to explain it.

PPPoE Configuration and Management
PPPoE (PPP over Ethernet, PPP based on Ethernet) refers to the operation of PPP on the Ethernet link, which is widely used in ADSL, community networking and other applications. PPPoE uses the Client/server model to provide a standard on a broadband access PPPoE server that is connected to a remote network by multiple hosts. The
