The IEEE802.1D Transparent Bridging packet service offers
complete protocol transparency and has inherent configuration
simplicity. Yet it provides excellent forwarding performance.
In contrast to Transparent Bridging, which provides an
"Always On" type of connection, PPPoA to PPTP Relaying
(PPPoA/PPTP), supports a session concept.
Similar to Transparent Bridging, PPPoA to PPTP Relaying is
multiprotocol and offers complete TCP/IP transparency.
An important advantage of PPPoA to PPTP Relaying is that it avoids
the complexity of a router, yet to a certain extent, provides
identical features.
Next to the Bridging and Relaying packet service, the
contains an IP router.
Point to Point Protocol (PPP) combined with IP routing is the
technology of choice to create a small IP based home LAN.
Similar to PPPoA/PPTP , it provides a session concept. Additionally,
IP routing combined with Network Address & Port
Translation (NAPT) allows to multiplex users into a single VC.
The IP router can also be combined with Classical IP (CIP) .
Classical IP is a mature technique for creating classical IP networks
on top of ATM technology. It is widely supported by most, if not all
access routers.
Although not the original aim of Classical IP , it is mostly used for
connecting routers over wide area point to point links.
