How to combine multiple modems on the same network to increase throughput?

Question

Yota

At the cottage you need a powerful Internet. The choice fell on Yota. But you need to combine several yota modems so that they all work within the same network (to increase bandwidth).
How to do it - What equipment do you need/where to dig?
PS- One modem was connected to the DIR-320, we indulged, we realized that one modem is not enough. But DIR-320 (and other routers with one USB) do not have a socket for the second, third yota USB modem ... what should I do? All modems must be on the same network in order to forward packets through a free modem.

Answer 1

Well, here you can either prescribe special routing conditions so that the router sends different requests to different modems. But the linear streaming download speed in this case will not increase and will hang on one of the modems.
Or throw vpn home, where the aggregator will stand and wrap the traffic in the outside. Accordingly, in the country it is similar, all traffic is divided into modems. FreeBSD supports this at the kernel level and is very fast, Google Link Aggregation and Failover linux for anyone can also do something like that.
