Bzzt. You're overloading semantics. SPI's enumerate the set of packets for which a given security policy applies. That may have exactly zero to do with the QoS policies you'd like to apply. > > I didn't say it makes no difference.

By all means, let's just ignore silicon considerations. Moore's Law trumps all, obviously. -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
