Which Load-Balance Technique i should use?

Thu Oct 06, 2022 12:51 pm

Hello Everyone,

I have 2 Internet Lines , the 1st one is DSL with 8 Mbps download/1 Mbps upload , and another 4G router with 20 Mbps download / 5 Mbps upload , i would like to aggregate both speeds to give the end user when downloading/uploading a file a total speed of 28Mbps / 6 Mbps , i have seen some tutorials online and i got the below issues.

1-The Download speed is aggregated , i can see from interface statistics that both WAN Links are used and from speed test it's good.
2-From the upload side , only 1 Link is used to upload at a time , it's not aggregated so i don't know why.
3-When i download a file and disconnect 1 of the WAN Link.. the download is disrupted , for exampe..if i ping 8.8.8.8 and disconnect the WAN Link the ping stops , but if i try to ping google.com it will work on the 2nd link so i am wondering if the load balance is a flow based and the flow is saved on the Mikrotik and thats the issue.
4-From mering the download speed i suppose it's a per packet load balancing , but i am not sure.
5-I have attached the topology for your reference.

You cannot aggregate speed!
Dual wan gives you.
a. redundancy in that if one provider is not available you are still providing internet for users ( need two different providers )
b. more bandwidth available to share amongst all users.

One cannot combine ISPs for a single session.
Since you have basically a 1/3 2/3 scenario, you could do pcc load balancinng where the router points users to WAN2 more frequently than WAN1.

or do bandwidth based load balancing......

Thank you very much for the 2 PDFS , i am wondering why when i perform a speedtest from my laptop , i can see that the speed is aggregated , i get more than 30Mbps , when i disconnected the DSL Router , i get the 4G Speed , but when i download a torrent file it will just pick a single Link of the 2 WAN Links..so i assume the load balance here is per flow , i have worked on some SD-WAN Vendors Routers , they provide a per packet load balance so the 1st packet goes to 1 Link the next Packet go to the 2nd Link eventually the speed will be doubled , dunno if this is supported on Mikrotik because if it's per flow load balance then each session will use a random link , i will give the above methods a try and let you know the feedback.

check posts from gotsprings, he has tried every sd-wan package out there for MT devices.
I think the one he has settled on is called smoothWAN
