Moreover, TCP is a connection-oriented protocol, requiring a connection to be established before data is exchanged, whereas UDP is a connectionless protocol, which can result in data packets being lost in transmission or arriving out of sequence. NordLynx is a new-generation VPN protocol that provides faster speeds than other well-established protocols. It’s called NordLynx, and it’s based on the WireGuard framework. Simply put, UDP prioritizes fast data transfer at the expense of reliability, while TCP prioritizes reliability over speed. In July 2019, NordVPN announced that they created a new protocol to combat issues older ones have. What is the difference between UDP and TCP? In the ExpressVPN apps, users can toggle between UDP (User Datagram Protocol) or TCP (Transmission Control Protocol) within the app settings if they wish. It has been widely audited by trusted independent researchers, making it appropriate for deployment even in sensitive environments. OpenVPN can most easily be configured to mask itself as ordinary internet traffic, which helps it evade detection by filters and firewalls.
It’s available freely for all platforms and is held in high regard by the community, and it is widely adopted among consumer VPN services. OpenVPN is a highly configurable open-source protocol. This allows Lightway to be used in a wide range of scenarios. In addition to running on the UDP protocol, Lightway also supports TCP, which can be slower than UDP but connects better on certain networks.
Nordlynx vs openvpn code#
We’ve published the source code of Lightway on GitHub under an open-source license, ensuring transparency to our users. When it comes to security, Lightway uses wolfSSL, whose well-established cryptography library has been extensively vetted by third parties, including against the FIPS 140-2 standard. Lightway does the minimum needed to get you connected quickly and securely, so you might even notice less battery usage.
Establishing a VPN connection might take only a fraction of a second, depending on your network, and you’ll stay connected to the VPN even when your device switches networks. Built from the ground up by ExpressVPN, Lightway is created for the modern world, forgoing features that are no longer needed from a VPN and implementing those that provide a smooth, secure experience.
