UDP Scan (-sU) | Nmap Network Scanning
Both UDP and TCP run on top of IP and are sometimes referred to as UDP/IP or TCP/IP; however, there are important differences between the two.For example, UDP enables process-to-process communication, while TCP supports host-to-host communication. Furthermore, TCP sends individual packets and is considered a reliable transport medium. On the other hand, UDP sends messages, … ssl - Difference between DTLS and TLS - Stack Overflow DTLS is an implementation of TLS over UDP (a datagram protocol). per wikipedia, TLS uses TCP, and DTLS uses UDP, so all the classic differences apply. UDP communications exist as streams of packets with no ordering, delivery reliability, or flow control. applications that use datagram protocols need to make sure they can handle these concerns OpenVPN over TCP vs. UDP | what are they and what should Jun 23, 2013 udp-server · GitHub Topics · GitHub

Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. TCP or UDP for Logging – Which One to Use? Some reasons for using UDP for transporting logs are: Legacy (some devices/software do not support TCP for logs, especially old devices). Application performance – UDP is send and forget; don’t wait for server confirmation! This is extremely important when you … Testing Sophos SSL VPN Performance - UDP or TCP? SSL VPN over UDP still attempts to connect to the VPN server on port 443, but unlike HTTPS traffic that uses TCP as a transport protocol, it uses UDP. Some firewalls and proxies may flag this as suspicious and drop the traffic. It can also be seen as peer-to-peer traffic (which it actually is) and again be dropped.
