The goal of which is using hardware interrupt moderation of NIC and good motherboard. Maybe second cache of CPU to be more and more is better (but i have't tests) I use that configuration: The hardware: S3000AHV motherboard with Core2Quad 6600 processor (4 cores). motherboard has 82571 chip NIC, the two additional cars: EXPI9402 (PCI-E x4 two 10/100/1000BaseTX ports) and EXPI9400 (PCI-E x1 one ethernet port) is installed to the system. The goal of which is to load all cores of CPU or use yandex em(4) driver who uses different rx kernel threads on every CPU/core (if you have one NIC) for the driver see: people. yandex . ru/~wawa The software: 1. FreeBSD 7.0, mpd5.3 + ipfw + dummynet (shaping on this machine - bad idea! for performance. but it is first my setup and works very stable) 2. FreeBSD 7.2, mpd5.3 + ng_car + ng_bpf (rate-limiting on this machine - the perfomance of traffic processing is very good, because ng_car & ng_bpf is in kernel space, but have trouble described in PR kern/137881, i think on FBSD 7.0 it may be works fine, but no test are made, i'm busy) 3. Use PPPoE concentrator and traffic shaper/rate_limiting on different machines - it is best but is very older practice. I think the best choise today is #2 Dmitriy Zamuraev, system administrator The Netline NSP company Russia, Tyumen.

The solution you are implementing will mean to make hundreds of users share= the same broadcast domain. As all your FTTH and other DSLAMS would be work= ing in bridge mode. This scenerio is not safe as if anyone of your clients will start his own p= ppoe server you will be in strange trouble, there can be other issues too. I guess your DSLAMs must have built in pppoe support and radius client, if = its there then every port of dslams can be separate broadcast domain. This = will cause you extra routing management (depending upon your scsnerio) In case your DSLAMS have no pppoe feature then i would suggest you to at le= ast put every DSLAM's uplink port in deparate VLAN and connect pppoe server= using trunk port or multiple single ports. And before implementing this solution consult your DSLAM vendor cause ive o= bserved problems in ipdslams when used in bridge/transperant mode.

The problem is, HOW many VLANS can you open? If I use the Transmode TS DWDM (GE) and/or CWDM (10GE) then I am limited to 4096 VLAN's. So, if you have inside this network business customers which require seperated VLAN routing you run out of VLAN's Yes, I can use a biger system, but this cost at least twice of the "Transmode TS" system. Juniper is much more expensive. > And before implementing this solution consult your DSLAM vendor cause > ive observed problems in ipdslams when used in bridge/transperant > mode. I am already in contact with Iskratel in Kranj/Slovenia, because the Distributor in Germany is a little bit to small for the Project and I get direct help from there engineers to implement this. The only difference between is, that my Servers are running entirely "Debian GNU/Linux" and where it fit better, FreeBSD.
