TCP/IP packets are directly exchanged. Raw IP has both advantages and disadvantages. Advantages: <UL> <LI> No handshaking (= faster connections)</LI> <LI> Authorization by Caller ID (= fast, safe, no password)</LI> <LI> Fixed IP address (= a broken connection can be continued by redialing)</LI> <LI> Higher data transfer rates</LI> <LI> Better stability (smaller driver = almost no bugs)</LI> </UL> Disadvantages: <UL> <LI> No handshaking => Configuration must occur beforehand (IP addresses,...) => sensible to use for only for one provider at a time </LI> <LI> Authorization only by Caller ID => Dialin only possible from one's own number</LI> <LI> Fixed IP address => must be known ahead of time, more IP addresses required, no dynamic assignment of addresses possible.</LI> </UL> From this summary it should be clear under what conditions it makes sense to use raw IP.</P> <HR> <A HREF="i4lfaq-15.html">Next</A> <A HREF="i4lfaq-13.html">Previous</A> <A HREF="i4lfaq.html#toc14">Contents</A> </BODY> </HTML>
