Cloud Router PPPOE Connections Handling Problem

RouterOS General
1

Dear Friends,

I’m a Technical Manager for some ISP company. We are using Mikrotik from about 3 years and I’m watching the forum since that time but this is the first time I post on it and hope to actively take part on it in the future.

First I would like to appreciate Mikrotik products and efforts to produce these great good routers.

We Usually use an x86 machine as a PPPOE server. I know that most of the professionals will not approve, but we only use simple queue for the PPPOE clients even when the online for each server reach about 2000 clients. To do so, we use a powerful x86 servers. starting from about 1500 online clients, the performance starts to decrease and the internet service become very slow. We identify this as a router CPU limit problem.

To solve this problem we switched to use the cloud core router CCR1036 (with ROS 6.0RC13). Unfortunately, we had been very disappointed when we used it because when the online PPPOE clients reach 800 - 1000 the router became very unstable and even the local network attached directly to the router cannot be reached.

I think this is an ROS 6.0 problem. Any advise on this problem will be highly appreciated. Sorry for long introduction.

Best Regards

Firas

Hey,

we have about 2500 users on our network, and use titanwireless MikroNoc’s for our LNS (pppoe servers)
my advise is simply to have 2-3 of them on the same network.

They basically self load balance, you will see about a 45/55% ratio of users logging into each box.
the biggest benefit to this other than load is redundancy.

i have tried using a CCR on our live network in a remote part of our network and found it still a little too buggy and will be removing it shortly. The main issue for me at the moment is the broken Queues and the OSPF bug. they are nice units though when it comes to the raw CPU power.

Hi

I read today that the cloud router has an EoIP limitations i the current ROS6 because it uses only 1 CPU for it. May be this is my problem as we use EoIP extensively in our PPPOE router and may be that explain why when we had 800 - 1000 online users we get almost a dead router.

you’d find better performance with freebsd/mp on x86.
