Faster Internet with MPTCP (Multipath TCP)

MANY THANKS TO ALL MY PATRONS on   / onemarcfifty   !!!

Multipath TCP or MPTCP could be the next big thing in the linux kernel. In this episode I built a Test lab with my Proxmox and simulate three slow connections which I aggregate at the other end into a faster one using MPTCP. In real life you could aggregate 4G, 5G, 3G, LTE or Starlink, Docsis or DSL lines into one fast line.

The second episode (OpenMPTCPRouter) is here    • Faster Internet with OPENMPTCPROUTER ...  



The Multipath TCP Project site is here: https://www.multipath-tcp.org/

To test if you are using MTCP V0 : http://amiusingmptcp.de/
Compare the two RFCs here: https://www.ietf.org/rfcdiff?url1=rfc...
Yannick / ysurac OpenMPTCPRouter page is here : https://www.openmptcprouter.com
and his github : https://github.com/ysurac

In order to install the Multipath TCP enabled Kernel do the following steps:

(remove the spaces or underscores in the URLs)

wget https:/_/raw.githubusercontent.com/onemarcfifty/mptcp-tools/main/makescript.sh
chmod 755 makescript.sh
./makescript.sh
this creates the fetch_ycarus_kernel.sh
chmod 755 fetch_ycarus_kernel.sh
./fetch_ycarus_kernel.sh
this now creates two debian packages in the /tmp directory
apt install /tmp/llinux-image....deb
apt install /tmp/llinux-headers....deb



in order to enable boot menu in Grub make sure you have the following lines in /etc/default/grub


GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10



then launch update-grub


In order to add the routes do the following:

wget https:/_/github.com/multipath-tcp/mptcp-scripts/blob/master/scripts/rt_table/mptcp_up

cp mptcp_up /etc/network/if-up.d/
chmod 755 /etc/network/if-up.d/mptcp_up
wget https:/_/raw.githubusercontent.com/multipath-tcp/mptcp-scripts/master/scripts/rt_table/mptcp_down
cp mptcp_down /etc/network/if-post-down.d/
chmod 755 mptcp_down /etc/network/if-post-down.d/mptcp_down




Other commands I used:



iptables --list
iptables --list-rules
ip route list tables

iperf3 -s

iperf3 -c (ClientIP)
ip route list table (name of NW interface)
