I have 3 diffrent ISP providers
i need to get sum of speeds on router 1
i also have externel ISP with high speed on router 2
what software i have to install on router 1 and router 2 in order to agregate all ISP providers ?
You need https://www.openmptcprouter.com/
and you won't really get the agregated speed of all three connections on a single client, unless you use protocols supporting that kind of traffic.
To make this work using vanilla OpenWrt (ie not a third party fork), you would need the mptcpd package, but this is only available on x86-64 as far as I can see.
See:
so there is no solution to make it all work on simple router OpenWrt? like 500 Mhz 64 RAM
The mptcpd package in operation is going to be highly cpu intensive (eg sorting and reordering streams of packets ). Your 500MHz 64MB outdated router will grind to a halt if it does not oom-crash first.
Got it , so i have to replace router 1 and router 2 with mini PC then install OpenWrt x86 and mptcpd on both miniPC and make config on both miniPCs?
Yes, but the "miniPC" will have to be "mini" in size only. Think very fast multi-core cpu and very large ram, multiple real ethernet ports (not usb ones) etc.
For example, this is done in large corporate environments using server grade hardware between their data centres. Your aggregated bandwidth is a great deal lower though, so that is in your favour.
