MPT - Multi-Path Tunnel

What is this?

This is a small tool for network layer multipath. Works like a multpath VPN application: create a logical tunnel interface over the native phisical interfaces and share the tunnel's traffic between them.

The datapath encapsulation of this application is completely standard! See RFC 8086 for the details of the GRE-in-UDP architecture. We have an additonal multipath signalig, which is not standard, but we have some initial effort on that (see this internet draft). So this is a GRE-in-UDP VPN application with multipath extension.

Compilation

Install the dependencies:

$ sudo apt install gcc-multilib libssl-dev net-tools iproute make libev-dev

Compile

$ cd mpt
$ make

Configuration

Here is a guide for configure this application. There are some steps which makes this readme too long so please visit the link below. More information: https://irh.inf.unideb.hu/~szilagyi/wp-content/uploads/2019/05/usermanual.pdf

Running the software

Start the mptsrv binary in root mode. Double check if the configuration is correct and match with the real world test setup.

Resources

The intent of the software is nework layer multipath research. We have a few papers with the capabilities of the software, including new results in the research area:

Aggregating throughput of many ethernet links
Aggregating throughput of high bandwidth ethernet links (Gbit/s)
Super-aggregating Wi-Fi and LTE and Wi-Fi and Ethernet
Quick failover on link errors without connection loss
Multipath HD video streaming
Vertical handover between Wi-Fi and cellular networks
Android implementation and QoE triggered application agnostic multipath
and few more approach...
