Hi,
for the new location, Telekom offers a Hybrid access and wants to sell its own Speedport.
hybrid means some bonding of a DSL 6000 :"( with an LTE 25M-50M.
I have the option to take over a nearly new RB1000AHx4.
How would it be possible to integrate
br
the stuff they do is huawei proprietary. it is dome with modified GRE tunnels, and there’s a device called HAAP that is merging the two halves together.
in most cases the traffic uses the LTE link as the idea of this hybrid access came from the fixed access folks who wanted to work around shitty copper accesses. (i have all specifics of the solution but cannot share them here)
HAAP and the special CPE is responsible for packet-reordering upon GRE decapsulation. this requires some buffer which introduces some extra delay though.
this way even a single tcp stream can be forwarded on both paths.
how to do it via mikrotik? definitely not with bonding.
you can have 2 routes and RouterOS will do per destination load balancing: 1 stream will either go to LTE or to DSL. 2 ‘wan’ addresses, it works, but cannot deliver proper load sharing with just a few streams.
if your clients(apps) support MP-TCP, then it’s all fine, it would balance even a single stream, but in many cases this support is missing from ‘regular’ programs.
i have another idea of using L2TP and MLPPP, but since routeros doesn’t support L2TP sequencing, you would end up with a loads of OoS segments on the far end due to inconsistent delays on the two available paths and throughput will suffer heavily, so you’ll lose more than you can gain.
