The User Datagram Protocol (UDP) is simplest Transport Layer communication protocol available of the TCP/IP protocol suite. It involves minimum amount of communication mechanism. UDP is said to be an unreliable transport protocol but it uses IP services which provides best effort delivery mechanism.

Can be both: Every version of Microsoft Windows from Windows XP onward [4] includes an installed Remote Desktop Connection (RDC) ("Terminal Services") client ( mstsc.exe ) whose version is determined by that of the operating system or by the last Apr 16, 2019 · User Datagram Protocol (UDP) User Datagram Protocol (UDP), defined by RFC 768 is a connectionless protocol. This protocol also operates at the Transport Layer of both the Open Systems Interconnection (OSI) reference model and the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack. You can't use TCP over Mcast since TCP is session based. As you stated UDP is the protocol of choice for Mcast applications. Other non session based protocol such as IGMP, OSPF, EIGRP, RIP also use Mcast for message delivery. TCP and UDP are two of the most commonly used connection protocols used for data traversal across the Internet. Data travels across the Internet in packets. Think of them like letters: Like letters, the packets have an envelope with a to/from address on them. TCP and UDP are just two types of envelopes. UDP: The User Datagram Protocol z UDP is another transport protocol in the TCP/IP suite z UDP provides an unreliable datagram service – Packets may be lost or delivered out of order – Users exchange datagrams (not streams) – Connection-less – Not buffered -- UDP accepts data and transmits immediately (no buffering before transmission) TCP is a reliable protocol. UDP is a unreliable or best-effort protocol. Unreliable you might think? Why do I want data transport which is unreliable? Does that make any sense? Let me tell you a little story to explain the difference between the two protocols.

Real Time Protocol (random UDP ports) Closing Remarks. In conclusion, although TCP and UDP both ride over IP, they transmit very differently. TCP is slower, yet more reliable which is great for communication that cannot tolerate loss. UDP on the other hand is much faster, has less bandwidth overhead, and can tolerate more loss.

This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client. Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. Ethernet (UDP and TCP) Ethernet (UDP and TCP) Ethernet UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) are the basic communication languages or protocols of the internet. They can also be used as communications protocol in private networks.

TCP (Transmission Control Protocol): TCP is a layer 4 protocol which provides acknowledgement of the received packets and is also reliable as it resends the lost packets. It is better than UDP but due to these features it has an additional overhead. It is used by application protocols like HTTP and FTP. UDP (User Datagram Protocol): This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

They can also be used as communications protocol in private networks. 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. A suite of networking protocols that includes TCP, IP, UDP, and many others. TCP/IP (Transmission Control Protocol/Internet Protocol) The specialized protocols that work together and belong to a protol suite. TCP et UDP sont les deux protocoles principaux de la couche transport. Lors de la configuration d'un routeur ou d'une box internet, il n'est pas rare d'avoir à choisir entre les ports TCP et les Can be both: Every version of Microsoft Windows from Windows XP onward [4] includes an installed Remote Desktop Connection (RDC) ("Terminal Services") client ( mstsc.exe ) whose version is determined by that of the operating system or by the last
