RB 1200 PPPoE Sessions

Fri Dec 09, 2011 3:08 pm

Have anyone tested RB1200 as a pppoe server (BRAS)?
How many sessions does it support? With previous routers we couldn't go higher than 500 session.
Because the router gets loaded.

Thank you

As RB1200 has level 6 license, it must accept more than this (Unlimited) >>

Level 6 has no limits.

But from what i understand, you concern is how much clients it supports while running bellow 100%.

Well, this is a very tricky answer, it depends on the config of the RB1200 and the BW that you give to each customer.

Router performance normally is measured in packets per second, and if you go to the RouterBOARD page you can see that for router it does about 117.000 pps for big downloads (MTU=1518), and this is quite allot for it´s price.

For a simple iperf tcp test between to linux machines with RB1200 in the middle, with routing and simple firewall rules (connection state evaluation), it does about 680Mbits of throughput.

But for a small difference in price, you have RB1100AH that almost doubles the performance of RB1200 (208.500 pps)

How many sessions?

Average throughput per session?

Do you have complex firewall rules?

Are you running any other features? (NAT, QoS, proxy)

etc etc

We use a RB1200 as PPPoE server.
ROS version: 5.8
About 70/80 simple queue simultaneously
No traffic shaping
External radius
A few filter rules

CPU: 30-50%

I don't think it will manage 500 users...

consider a RB 1000 could authenticate 600 pppoe users without any other service
