This User Datagram Protocol (UDP) is defined to make available a datagram mode of packet-switched computer communication in the environment of an interconnected set of computer networks. This protocol assumes that the Internet Protocol IP is used as the underlying protocol. This protocol provides a procedure for application programs to send messages to other programs with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery and duplicate protection are not guaranteed. Applications requiring ordered reliable delivery of streams of data should use the Transmission Control Protocol TCP. l
The Novell protocol is SPX
This would be UDP. The User Datagram Protocol. It has no error checking or correction or congestion measures.
UDP
Datagram is UDP that is connectionless,best effort-delivery protocol which means it sends data and doesnot take responsibility for the data's integrity.But,it is useful when large number of data has to be sent. Kritika Raj
Transmission Control Protocol (TCP) is used when data reliability is needed since it is connection oriented and guarantees delivery.
Guaranteed reliable delivery is provided by TCP transport.
user datagram protocol
A datagram socket represents a connectionless, non-guaranteed communication protocol. It represents the UDP protocol in the TCP/IP suite.Contrast this with a stream socket, which represents a connection oriented, guaranteed, communication protocol. It represents the TCP protocol in the TCP/IP suite.UDP is the underlying protocol for TCP. If you are talking OSI model, UDP is layer 3, and TCP is layer 4.
I believe Skype uses UDP or User Datagram Protocol.
• low overhead • no flow control • no error-recovery function
it indicates which layer 4 protocol is carried in a datagram
