Multipath-TCP in ns-3

TL;DR

This paper introduces a new ns-3 simulation model for MultiPath TCP (MPTCP) that adheres to RFC 6824, supporting subflow management and TCP NewReno loss recovery, demonstrated through example simulations.

Contribution

The paper provides the first detailed implementation of an MPTCP model in ns-3 aligned with RFC 6824, including subflow management and loss recovery features.

Findings

The ns-3 MPTCP model closely follows RFC 6824 specifications.

Simulation results demonstrate the model's correct functioning.

Supports TCP NewReno loss recovery on subflows.

Abstract

In this paper we present our work on designing and implementing an ns-3 model for MultiPath TCP (MPTCP). Our MPTCP model closely follows MPTCP specifications, as described in RFC 6824, and supports TCP NewReno loss recovery on a per subflow basis. Subflow management is based on MPTCP's kernel implementation. We briefly describe how we integrate our MPTCP model with ns-3 and present example simulation results to showcase its working state.
