So, you'll have 96*200 possible PPP clients. How many concurrent PPP sessions do you care to support? And more importantly, how much aggregate bandwidth? > What I now need are a PPPoE Severs (round-robin and loadbalancing) which > must work using FreeRadius and PostgreSQL. Don't understand what you mean round-robin and loadbalancing?

FreeBSD has a RADIUS library in base. The two notable users of libradius are ppp and net/mpd. The only choice in a ISP environment I think is the net/mpd5 port. Read the outline here: http://www.freebsd.org/cgi/url.cgi?ports/net/mpd5/pkg-descr It is very good and is actually used in large setups. > So, what I like to know is, if I have a 1GE and 10GE network, how many > clients can one PPPoE Server handel and what are the CPU/Memory > requirements? Can't reply, but keep in mind that filling a 10GE pipe is a hard task on its own. I *think* having more low fidelity BRASs, will serve your needs better that a few high fidelity ones. > [snipped] > > Note 1: Even if I use a Sun Fire, I would prefer a microBSD > running from an industrial SD/CF card. MicroBSD seems OpenBSD based. Can't comment on this. You can try NanoBSD and TinyBSD which are FreeBSD based and I believe can fit the bill. These two run with their filesystems read-only mounted which is ideal for flash memories. Nikos
