Routerboard 500, Microtik OS and PPPoe

Hardware MikroTik hardware general

Hi

We are currently using FreeBSD PPPoE servers, each handling 150+ concurrent sessions. The number of pppoe connections are ever increasing and in very near future we may have 500+ concurrent connections in each server.
We are also looking at the possibility of using micotik Router OS on Routerboard 500 as an alternative to our current system.

There are few points which I am not sure of :

Microtik Router OS manual says that it can handle 1000 concurrent connections .The same manual also mentions that each pppoe connection consumes aroung 50KB of memory. But the 500 series board has only 32MB memory. In that case how is it going to handle that much of concurrent connections?

Are there any other issues related with it?

I really appreciate answers from 500 series users who have used this hardware in production environment.

Thanks

With v2.9, each PPPoE connection uses 8KB. The tx and rx queues can be as low as 10KB if you set them to bfifo and limit it by size to 5KB each (max of three big packets or lots of small packets).

For 150 PPPoE clients, you should be fine on a RB500.

This topic will get better responses on the forum.mikrotik.com . This forum is more for non MikroTik RouterOS issues.
