How to compensate for packet loss with a second provider?

Question

Mikrotik

Faced a problem. There is a user and two providers connected to the MikroTik router, both providers have packet loss. It is necessary that the user sends packets to MikroTik, MikroTik sends identical packets to both providers at the same time, then response packets come from both providers, and are combined to compensate for broken packets, and sent to the user as a whole. Tell me how to implement it or offer your own version. It is not possible to connect to another provider. The problem is exactly in the provider, I checked.

Answer 1

what you propose is writing your own TCP stack,
the router does not repeat anything, if the packet is lost, then it is gone and there is nothing to be done about it, this is RFC, after which the client will send a second packet.
I don’t know on which channels your providers are connected, but if it’s not a radio, then write a claim to the provider.
Another thing is that in my practice, 99% of the problem is in the settings or the equipment is not correctly selected.
If you are sure that everything is fine with you and the provider cannot do anything, then a traffic optimizer will come to your aid, read https://habrahabr.ru/company/croc/blog/214693/
