Same packets over different ISP's for reliability possible?

Hi,

I was wondering if something like this is possible:

Two Mikrotiks. Each with two connections to internet.
Would like to create two tunnels, GRE, IPSEC or ? doesnt matter much.
Then for reliability I would like to have the option to send some traffic through both the connections to make sure the traffic reaches the other end.
The packets would natually have to be tagged in some way for the other end to keep track of which packets are already received (and just discard dublicates)

I would use this for important realtime data like VOIP, Video Conferencing and RDP in and out of China where packetloss and breakdown are a daily struggle.

If someone know Talari or Fatpipe they have these possibilities, but they are expensive af.

Hope someone have an idea. Thanks.

Hi.

I didn’t try it. But i can give you some ideas, you could use routing igm-proxy to route multicast packages using GRE interfaces.

Thanks for your reply. I will def. look into that. Thanks.

A non-MikroTik answer here … You may want to look at the SDWAN space. They offer a lot of products. Two I can think of off the top of my head would be PfR / iWAN, Cisco, alternatively a new product Preseem from the guys that make Nightshift is coming along. They are targeting WISPs so it likely wouldn’t be out of the question for them to integrate with MikroTik devices which may be a little friendlier answer.

Either way both essentially monitor and look deeply at the QoE, quality of experience, per flow on the network. The iWAN approach then will dynamically route each flow based on the best path it identifies for it based on network condition and pre-configured rules. The Preseem product I believe is still more hands off. They are still building the proactive change piece from what I understand.

I’m not aware of any “hub” like device or software setting within MikroTik that would allow traffic to flow equally across more than 1 WAN link like you want.
