Use multiple WAN for upload and download both ?

Hi, we have 3 ISP feeds.
200Mbps each.

And your average peak hours usage will be like 500-550Mbps download and 500Mbps upload, as we sell our upload to a some mini data center clients.

We need all 3 ISP feeds to be simultaneously and the packet request should automatically choose which WAN has the best latency, and it should automatically choose path.

So, basically Tx should use all 3.

Rx should use all 3.

Im choosing to get this router,

So, is it all possible or is there any kind of limitation in Microtik ?

Let me know, before I place the order.

It will easily fulfil your needs as described.

Okay!
But how do I configure ?
Which is the option ?

I asked a friend and he said, Microtik has limitation to use only 1 WAN for upload.
It cannot use more than 1 WAN for upload.

Is that true ?
If false, how do I fix his situation ?

Search for pcc load balancing. Start here. http://wiki.mikrotik.com/wiki/Load_Balancing

He said, ECMP doesnt happen in CCR1009 , which he is using now.

Means he is not able to select 2 WAN for upload.

We already tried PCC, but it doesnt choose the best path, so we have to force a particular WAN for upload. Is there a way, we can make the settings that mikrotik takes the best path for upload ??

Unfortunately I don’t have such relevant experience with this type of load balancing but I saw some kind of metered approach here on the forum that should measure the actual throughput of the wan links and set the ratio according that. Search for it. Maybe you would need to make some tryouts…

Anyway what does mean “the best path” for you?

Can someone Moderator or core developer throw some light how to do this ?
Or shall we consider this as a limitation for microtik ?

There were two talks about load balancing at MUM USA 2012.

The one that allowed proportional load sharing based on actual throughput is this one:

Its behavior was more like: fill up link 1 then use link 2 if link 1 is full, then use link 3 if links 1 and 2 are full.

It’s a little different than you want, perhaps, but in the end it gets the same effect - to load balance differently-sized internet connections proportionally.

That is not a balance then :frowning:
Its fill and switch method

Then try the other method using PCC:

Let me go through. Hope it works, as we cannot afford Cisco.
We have to use Microtik only.
