There are two types of Internet Protocol (IP) traffic. They are TCP or Transmission Control Protocol and UDP or User Datagram Protocol. TCP is connection oriented – once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol. Multiple messages are sent as packets in chunks using UDP.
OS Rule Description Port Protocol Direction; Windows Server 2016. Windows Server 2019. Cast to Device functionality (qWave-TCP-In) Inbound rule for the Cast to Device functionality to allow use of the Quality Windows Audio Video Experience Service. TCP and UDP. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are used to transmit network data to and from server and client applications. The main difference between the two protocols is that TCP uses a connection-oriented transport, while UDP uses a connectionless type of communication. RDP version 8 is the first generation of the Remote Desktop Protocol that uses UDP alongside TCP for data transmission. Provided the RDP client supports RDP 8 (e.g. Windows 7 with RDP 8 Update, Windows 8, or Windows 10), the Windows 2012 RDSH server can transmit data using both UDP and TCP. Applications That Use Both UDP and TCP. There are some protocols that actually use both UDP and TCP. This is often the case either for utility protocols that are designed to accept connection using both transport layer protocols, or for applications that need the benefits of TCP in some cases, but not others. UDP – User Datagram Protocol. Both TCP and UDP are built on top of the Internet Protocol (IP), and both send bits of data, known as packets, to and from IP addresses. While both protocols do the same job, they go about it in very different ways. TCP is more concerned about accuracy. Using UDP in LabVIEW Because UDP is not a connection-based protocol such as TCP, you do not need to establish a connection with a destination before you send or receive data. Instead, you specify the destination for the data when you send each datagram. What is User Datagram Protocol (UDP/IP)? UDP is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communications by not requiring what’s known as a “handshake”, allowing data to be transferred before the receiving party agrees to the communication.
May 27, 2019 · When you see that a tunneling protocol uses TCP port or a UDP port, it means that it is setting up a connection between your computer and the VPN server using one of these two protocols. Whether a VPN uses TCP, UDP, or both can make a significant difference in its performance. 10.18. Protocols Using UDP. UDP is especially useful in client-server situations, when a client sends a short request to the server and expects a short response if either the request or response is lost, the client times out and tries again if all is well, only two packets are required
User Datagram Protocol is a simpler message-based connectionless protocol. Connectionless protocols do not set up a dedicated end-to-end connection. Communication is achieved by transmitting information in one direction from source to destination without verifying the readiness or state of the receiver.

Wake-up proxy also uses ICMP echo request messages from one client to another client. Clients use this communication to confirm whether the other client is awake on the network. ICMP is sometimes referred to as ping commands. ICMP doesn't have a UDP or TCP protocol number, and so it isn't listed in the below table.
