-\section{Related Work}
-
-\subsection{Nix: A Safe and Policy-Free System for Software Deployment}
-
-Nix addresses significant issues in software deployment by utilizing
-cryptographic hashes to ensure unique paths for component instances
-\cite{dolstra_nix_2004}. Features such as concurrent installation of
-multiple versions, atomic upgrades, and safe garbage collection make
-Nix a flexible deployment system. This work uses Nix to ensure that
-all VPN builds and system configurations are deterministic.
-
-\subsection{NixOS: A Purely Functional Linux Distribution}
-
-NixOS extends Nix principles to Linux system configuration
-\cite{dolstra_nixos_2008}. System configurations are reproducible and
-isolated from stateful interactions typical in imperative package
-management. This property is essential for ensuring identical test
-environments across benchmark runs.
-
-\subsection{A Comparative Study on Virtual Private Networks}
-
-Lackorzynski et al.\ \cite{lackorzynski_comparative_2019} evaluate
-VPN protocols in the context of industrial communication systems (Industry 4.0),
-benchmarking OpenVPN, IPSec, Tinc, Freelan, MACsec, and WireGuard.
-Their analysis focuses on point-to-point protocol performance; throughput,
-latency, and CPU overhead; rather than overlay network behavior.
-In contrast, this thesis evaluates VPNs that provide a full data plane
-with peer-to-peer connectivity, NAT traversal, and dynamic peer discovery.
-
-\subsection{Full-Mesh VPN Performance Evaluation}
-
-Kjorveziroski et al.\ \cite{kjorveziroski_full-mesh_2024} provide a
-comprehensive evaluation of full-mesh VPN solutions for distributed
-systems. Their benchmarks analyze throughput, reliability under packet
-loss, and relay behavior for VPNs including ZeroTier.
-
-This thesis extends their work in several ways:
-\begin{itemize}
-  \item Broader VPN selection with emphasis on fully decentralized
-    architectures
-  \item Real-world workloads (video streaming, package downloads)
-    beyond synthetic iperf3 tests
-  \item Multiple impairment profiles to characterize behavior under
-    varying network conditions
-  \item Fully reproducible experimental framework via Nix/NixOS/Clan
-\end{itemize}

-\subsection{UDP NAT and Firewall Puncturing in the Wild}
-
-Halkes and Pouwelse~\cite{halkes_udp_2011} measure UDP hole punching
-efficacy on a live P2P network using the Tribler BitTorrent client.
-Their study finds that 79\% of peers are unreachable due to NAT or
-firewall restrictions, yet 64\% reside behind configurations amenable
-to hole punching. Among compatible peers, over 80\% of puncturing
-attempts succeed, establishing hole punching as a practical NAT
-traversal technique. Their timeout measurements further indicate that
-keep-alive messages must be sent at least every 55 seconds to maintain
-open NAT mappings.
-
-These findings directly inform the evaluation criteria for this thesis.
-All mesh VPNs tested rely on UDP hole punching for NAT traversal;
-the 80\% success rate sets a baseline expectation, while the 55-second
-timeout informs analysis of each implementation's keep-alive behavior
-during source code review.
