- Hi, This may be a FAQ question but I have been unable to find
- the answer to this question for a long time.
- WHY IS PPP BETTER THAN SLIP?
-
- To make this question less general I'll give a scenario that
- I'm currently invloved in.
-
- o I'm developing an application in which a 486 based
- workstation connects to a central database (after dialing up to a
- terminal server). A lot of data is interchanged between the user at
- the workstationa and the central database over tcp socket connection.
- Currently I'm using on the PC side SLIP provided by Chameleon with a
- 8250 UART talking to a Racal-Milgo Modem V42bis. That modem is capable
- of giving sustained 14.4kbs and 38.2kbs burst. Using SLIP my
- throughput (that is counting only usable data, not counting headers
- and retransmission) is around 8kbs. which I believe is pretty good,
- given thae fact that the database is not physically located in the
- same place as the terminal server but is about 250 miles away
- connected to the terminal server through a router and leased line.
-
- o Given this how much can PPP improve performance or what value
- can it add to the whole process.
-
- o As a side note, I have before me a recent article in CW
- titled "Remote user get TCP/IP sans LAN" which goes on to describe
- this prduct called "SupperPPP" whic is "...layered over the Microsoft
- Corp. Windows operating environment and Frontier's TCP/IP or any
- industry-standard Open System Interconnect communications protocols."
- This product, it seems provides TCP/IP functionality over
- serial lines and it "adds error correction, retransmission and speed
- to the older SLIP for remote TCP/IP networking.....speedwise PPP could
- translate into a tenfold improvement over SLIP"
-
- NOW is that really true. I mean I thought I was getting almost
- all I could bet from my POTS line using SLIP. Can it really be true
- that PPP is really that much superior to SLIP?
-
-
- Any help is appreciated.
