Faster Internet with MPTCP (Multipath TCP)

In radio, a device that aggregates several antennas into one connection is called a beam former. The opposite of a multiplexer.

[@OneMarcFifty]

Hi, many thanks for the feedback ;-) Even though we're not looking at the specific use case of radio here ;-) So the opposite of the multiplexer would be a de-multiplexer ;-)

Wow. I was looking into this about 5 years ago to see how I could work from my remote village in kashmir as I work from home so could be based anywhere. I started to look into peplink routers and speedfusion but then for some reason didn't go any further. I recently became more interested and landed on your great channel. Hopefully with your experience I might be able to progress my original plan of Internet bonding.. Thank you for this great work.

Brilliant content, man. I've just set up my first load balancing router and channel bonding is next on my to do list.

You may use bmon or ntop for the NIC speed, iperf3 to measure throughput and possibly ntopng. Traceroute and pingplotter can be used for latency checks

[@coolkrini6230]

Thank you for the video. Amazing explanation. Even a person who is not much into technical can easily understand this.

[@YLandorin]

I tried this before the video came out (but someone gave me the hint on Marc's channel) and it works brilliant! I was able to speed up my 250 MBit connection to more than 300 (limited by 4G) and doubled my upstream from 40 to 80 Mbit. Quite easy to install thanks to the many VMs and the server script as long as you are a little Linux proficient. The redundancy is a nice bonus! Now if there just were a tutorial how to install this on an existing openwrt environment...

[@OneMarcFifty]

We might get to that :-) Problm will be to safeguard all your firewall, networks and DHCP settings etc...

I would love to see more content around this. Specifically, incorporation into full network setups and including ad blockers and other devices. I would also like to better understand the tuning options available and how the security works. For example, what else can I add on the VPS side? Thank you for all of your excellent work!

I use to use this trick with PFSense and an ADSL + Cable connection. Worked great. Not sure if it was MPTCP or not, either way I got the combined throughput on most everything.

[@OneMarcFifty]

Hi Jeff, many thanks for sharing - yes, you could do load balancing on many Router OS'es - Mikrotik RouterOS, pfSense, OPNSense and the like - also with OpenWrt. Usually they would NOT use MPTCP but rather aggregate the total bandwidth. But you would still benefit from that if a) the software(s) that you are using is using multiple streams or b) you have many people in the network round-robin between the connections.

What a fantastic explanation, I have been reading the multipath TCP RFC but had so many questions that you addressed well in this video! So here is something that am not sure about. Given that we are guaranteed now to get more out of order packets because some paths are faster than others, what is the cost of reordering those packets aggregated from the multiple paths at the destination?

[@OneMarcFifty]

Hi Hussein, many thanks for your feedback. The cost of reordering depends on the scheduler of course. Olivier Bonaventure has written a nice article on this: blog.multipath-tcp.org/blog/html/2018/12/09/the_multipath_tcp_packet_scheduler.html

[@julienchlebowski516]

Hey Marc, I'd like to make use of MPTCP wonders, but on LAN only : I am throwing together a bunch of servers that are all 2x or 4x 1Gbps NIC equipped. I have a 24 ports gigabit switch sitting there, unused. So I can live with wasting eth ports on the switch side. I'd prefer using 2 - 4 ethernet cables per host, and boost the throughput to ~ 2Gbps to/from hosts with 2 eth ports , ~ 4 Gbps for hosts with 4 eth ports, than spending hundreds / thousands on 10G switch and pci NICs, or dedicated infiniband / flexiblelom for the servers. Is there a way to make MPTCP work directly between these few hosts, and to get multi gigabit speeds on a budget ?? All hosts be running ubuntu 21.04, and will all be in the same room in a rack. Thanks for sharing your insight on that matter.

[@OneMarcFifty]

Hi Julien, you could use MPTCP for this but as you seem to be in an Ethernet environment, there is a much easier solution which is taylored for this - Ethernet bonding.

Hi Marc congratulations for the video which was something I was waiting for !! Question: can I use my server with debian linux on board instead of a remote VPS server since I have a 100MB vdsl with 70 MB down and 30 Mb up available? Thanks Massimo

[@LampJustin]

I don't think you're understanding right. You can of course use your local debian server but how are you benefiting from that? You can only benefit by having multiple links to the internet be it dsl, LTE, 3G, Starlink or Cable. This software just let the packets use different routes to reach its destination. If every server on the internet would also have it, then yes you could totally be fine using a local debian server with multiple uplinks, but since the server on the other end don't know that all those incoming packets are in fact from one person or computer, it drops the connection and Linux would fall back to normal TCP with which you'll never see higher speeds than that of your fastest line.

[@massimopovoleri1079]

@@LampJustin Hy modzilla thanks for the reply, actually it is a somewhat complicated topic and I think I have explained myself wrong: I will use a router with openWRT with MPTCP connected to two 4g LTE modems of two different operators in a mobile station. Then I will point to the address of the server that aggregates the streams. I wanted to understand if instead of the VPS server that will do the aggregation of the two flows I can use a physical server installed in my house where I have a very fast VDSL. Is that a stupid question?

[@LampJustin]

@@massimopovoleri1079 it indeed is complicated! But no its definitely not a stupid idea or question. The only thing that would limit your speed is your local vDSL connection. You therefore won't get more than 30 Mbit/s down on your mobile station.

would this benefit from gaming? because i tried the channel bonding technology from speedify and it sucks

[@OneMarcFifty]

Fair point. Now the difference - and that gives me hope - is that ECN was designed 20 years ago where video on demand and the like were not really an issue. Second difference is that router vendors just did not implement it where as with MPTCP they would need to explicitely discard it. We‘ll see - but what gives me additional hope is that network providers would actually make business if they continued to allow MPTCP. The future will show - either way it could also just be a temporary thing until we get highspeed internet everywhere which would make it obsolete.

Hi

honestly useless

[@OneMarcFifty]

Hi Leland, have you tried out MPTCP ? What is it exactly that you find useless ?

[@tech-net830]

Thanks for the great video. I did everything completely and without errors, however, amiusingmptcp.de returns no, what can be the reason?

[@OneMarcFifty]

Did you build this in a virtual environment or with two physical lines? If you only use one physical line then you can’t use multipath

@@OneMarcFifty Thank you so much for the response. The issue was because of using ubuntu 22.04. I have changed to Ubuntu 20.04 and everything works well. Thanks for your great videos. Just a quick question: 1.093670] MPTCP tokens hash table entries: 65536 (order: 7, 524288 bytes, linear) [ 1.093770] MPTCP request tokens hash table entries: 65536 (order: 7, 524288 bytes, linear) [ 1.093885] MPTCP: Unstable branch The Unstable branch is strange, what is the reason? Thanks a million

@@OneMarcFifty Sorry another question: when I want to configure routine and download the files, then use chmod 755 or chmod a+x. my IP rule does not change and I should configure the routing manually, what can be the problem? Thanks a million
