Howdy. We're looking at upgrading our border router(s) from 7500s to (something)
yet undetermined. What we would like to do is perhaps find a platform that is
smart enough to not route more outgoing traffic across a circuit than it can
handle. We have 4 outgoing links to the net at the moment. They all have the
same amount of bandwidth, BGP tends to want to send all of the traffic out to
the same two, so usually those two will carry 80-90% of our traffic while the
other two will carry like 20-30% combined. So if the first two connections burst
up a little bit, sometimes it can cause congestion its fairly rare; but any
congestion is unacceptable as you all know.<o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal style="TEXT-INDENT: 0.5in"><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"> I know the way BGP works, it
will use it rules to determine the way traffic will go. I was wondering if
anyone has heard of any good ways to handle this becoming more well known within
the last year or so I researched this last year and found that prepending and
doing things manually is pretty much the only way to load balance it. (i.e.
manually setting routes based on the best paths through our upstreams for each
connected network) I really just want to tell my router to load balance it;
since that is kind of what I'm paying $100,000 for in the first place, no? I've
also heard of gear from companies like route science that could possibly achieve
the same thing. But I've heard that it runs like $300,000 for a box, is there
anything a bit smaller for companies within the oc-3 range? That could accompany
my router?<o:p></o:p></SPAN></FONT></P>
