Subject: Re: 18 step process when a packet enters a router...
That was from my message. I just wanted to get it cleared (for
proprietary/confidiality issues) before posting it. I know a
sanitized version of it went out in one of Russ White's latest
books (his architecture book I think). Give me another day and
I'll get it posted.
