Re: (ASCEND) STAC Compression? (fwd)
Once upon a time Laurence G. Kahn shaped the electrons to say...
>>1) Stac (Ascend native version)
This is based on an early RFC draft and was obsoleted in development.
>>2) Stac-9 (Draft 9 version aka RFC1974)
AKA Stac LZS Option 3
>>3) MS-Stac (Mickeysoft MCPP or such aka RFC2118)
This is NOT MPPC (MS PtP Packet Compression or Per Packet Compression, I
forget which) - this is Stac LZS Option 4. Also provided in the RFC.
MPPC is yet something else, and is used by WinNT. Win95 uses MS-Stac.
>anyone know what/if usr total control frames talk in terms of compression
3Com TCs can do Stac LZS Option 3, and I believe Option 4 too - but they
do it in software so it slows things down.
The MAXen, and the Lucent PM-3, use HiFn Stac chips to do it in HW. The
older 4000s used the 9703 I think - current 4048/60 units, and the PM-3,
use the 9711 chip.
