libvma implementation for TLT

This is an official Github repository for the Eurosys '21 paper "Towards timeout-less transport in commodity datacenter networks.".

• For the simulator, please visit https://github.com/kaist-ina/ns3-tlt-tcp-public.

This repository provides a TLT impilementation (TCP version) on top of libvma (Mellanox's Messaging Accelerator). This implementation also includes DCTCP, SACK on LwIP stack inside libvma.

Guide

0. Prerequisites

Please refer to wiki of the original repository for the prerequisites. We tested the implementation on Ubuntu 18.04.

1. Setup

We placed all required kernel configuration on oneclick.sh.

source ./oneclick.sh

2. Build

Makefile should build libvma.so.

3. Run your application

Please use LD_PRELOAD to run your application with libvma.so.
