-\subsubsection{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.
-
-\subsubsection{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.

-\subsubsection{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.
