    All worth mentioning, I admit ... which is to say I would consider
    it... but from a purely academic point of view, having a properly
    accredited journal (with an appropriate editorial board and a proper
    peer review process) would do more for both *BSD and the individual.

    Certainly, I keep abrest of developments in our little world... and I
    respect some of the work that is published in various places for
    FreeBSD, but in the end, my goal is to have FreeBSD stack up against
    the Cisco and Juniper routers ... and that requires a broader audience
    ... both for criticism and for exposure.

    My basic argument on generic OS routing is this: If you never do
    anything unexpected, a closed system router (not even just closed
    source) will do you fine. They're generally reliable beasts and the
    facts about them are known to thier own liberate.

    If you need something to pass 1 gigabit of traffic with a maximum of
    600 kpps, a CCNE should be able to tell you which Cisco to select
    ... and you shouldn't have any problems until your needs substantially
    change.

    No such advice exists for FreeBSD or Linux ... or indeed Win-XP.
    While the latter two don't interest me, it should be no less
    possible. Can FreeBSD pass 600 kpps? Can FreeBSD pass 1 gigabit?
    It's taken months, but I can say yes ... with the right hardware.

    Now... we have an uphill battle. Common knowledge is that the only
    way to massivly route packets are custom ASIC's. Little mention is
    made of route clustering and other technologies that would scale
    generic system routing.

    Even though it's reasonably well known that the modern desktop
    processor has become rediculously powerful.

    Dave.
