 Wireguard \citep{donenfeld_wireguard_2017} is a state of the art VPN solution. Though Wireguard does not serve to combine multiple network connections, it is widely considered an excellent method of transmitting packets securely via the Internet, demonstrated by its inclusion in the Linux kernel \citep{torvalds_linux_2020}, use by commercial providers of overlay networks \citep{pennarun_how_2020}, a security audit \citep{donenfeld_wireguard_2020}, and ongoing efforts for formal verification \citep{donenfeld_formal_nodate,preneel_cryptographic_2018}.
 
-For each Layer 3 packet that Wireguard transports, it generates and sends a single UDP datagram. This is a pattern that will be followed in the UDP implementation of my software. These UDP packets suffer many of the same problems as will occur in my software, such as replay attacks, so the Wireguard implementation of such protections will be considered throughout. Finally, Wireguard provides an implementation in Go, which will be a useful reference for Layer 3 networking in Go.
