WebWhen a UDP connection occurs, there is no beginning, middle, or end to the conversation. Data simply begins to flow between the two systems. UDP is a very simple protocol and is used when speed is an issue. UDP packet receipt is not verified. An example of a use of the UDP protocol is DNS queries. Web1 day ago · The flow in the opposite direction is similar. Packets from valid peers are decrypted after being read from a UDP socket, then are written back to the kernel’s TUN interface driver. The changes we made in v1.36 modified this pipeline, enabling packet vectors to flow end-to-end, rather than single packets.
