hello and thanks
that's sounds cool. atm im reading a bit about carp and arp balancing. but i think, thats my solution. 500 MBit/s would be enough for my needs. so now, ive to get some boxes and do some tests... the lan party i spoke from is still far away (in early august i think). after this, i will post some links to cacti network graphs and some test results. i will start work in a few weeks. if i get some further questions, i will post them here... thanks marco Am Sonntag, den 29.01.2006, 09:50 -0500 schrieb Jason Dixon: > On Jan 29, 2006, at 6:22 AM, Marco Fretz wrote: > > > hello there > > > > we are planning a medium lan party with about 200 - 300 clients. > > it's a > > normal gamer lan party but there will be a lot of traffic. > > > > we will habe about 6 subnets (like 10.5.0.0/24, 10.6.0.0/24, and so > > on) > > that we have to route under each other. if we get a good sponsor we > > may > > habe some layer 3 cisco swiches that can do wirespeed routing. > > > > but i dont think so... i may have to get some 3 GHz Intel P4 Boxes > > (About 1 GB Memory) and do the VLAN Routing on these openbsd boxes. > > > > will i get about 1GBit/s throughput with such a box? > > is it better to use a gigabit ethernet card for each subnet or > > should i > > get the vlans on one intel card? > > > > is it better to route all vlans on one box or should i split up the > > routing on about 3 boxes? > > I just deployed a similar setup using a pair of OpenBSD/CARP servers > on inexpensive servers and a cluster of Cisco 2950s.
