Unreferenced date May 2009 Merge to Wireless Application Protocol date August 2011 Wireless DatagramProtocol defines the movement of information from receiver to the sender and resembles the User DatagramProtocol in the Internet protocol suite . The Wireless DatagramProtocol WDP , a protocol in WAP architecture, covers the Transport Layer Protocols in the Internet model. As a general transport service, WDP offers to the upper layers an invisible interface independent of the underlying network technology used. In consequence of the interface common to transport protocols, the upper layer protocols of the WAP architecture can operate independent of the underlying wireless network. By letting only the transport layer deal with physical network dependent issues, global interoperability can be acquired using mediating gateways.

IPstack In computer network ing, the Reliable User DatagramProtocol RUDP is a transport layer Communications protocolprotocol designed at Bell Labs for the Plan 9 from Bell Labs Plan 9 operating system . It aims to provide a solution where User DatagramProtocol UDP is too primitive because guaranteed order packet information technology packet delivery is desirable, but Transmission Control Protocol TCP adds too much complexity overhead. It extends UDP by adding the following additional features Acknowledgment of received packets Windowing and flow control Retransmission of lost packets Overbuffering Faster than real time streaming RUDP is not currently a formal standard, however it was described in an Internet Engineering Task Force IETF http tools.ietf.org html draft ietf sigtran reliable udp internet draft in 1999. It has not been proposed for standardization. Cisco RUDP Cisco in its Signalling Link Terminals either standalone or integrated in another gateway uses RUDP for Backhaul telecommunications backhauling of Signaling System 7 SS7 MTP3 or ISDN signaling. RUDP v0 no checksums is used for SS7 MTP3 backhaul RUDP v1 with checksum is used for ISDN PRI backhaul The versions are mutually incompatible and differ slightly from the IETF draft. The structure of the Cisco Session Manager used on top of RUDP is also different. Microsoft R UDP Microsoft has introduced another protocol they refer to as R UDP. It is used in their MediaRoom product for IPTV service delivery over multicast networks. This is a proprietary protocol and very little is known about its operation.

The header contains all the information sufficient for routing from the originating equipment to the destination without relying on prior exchanges between the equipment and the network. Headers may include source and destination addresses as well as a type field. The payload is the data to be transported.

merge to Datagram socket date October 2011 Datagram service is a service provided by Internet Protocol IP at the Internet layer . It is a connectionless, best effort, unreliable, message delivery service. Many higher level protocols including Transmission Control Protocol TCP a connection oriented service depend on IP s Datagram service, laying additional functionality on top. User DatagramProtocol UDP uses IP s Datagram service as well. Datagram service is often compared to a mail delivery service, the user only provides the destination address, but receives no guarantee of delivery, and no confirmation upon successful delivery. Datagram service routes datagrams without first creating a predetermined path. There is also no consideration given to the order in which it and other datagrams are sent or received. In fact, many datagrams in the same group can travel along different paths before reaching the same destination. Category Internet Protocol Compu network stub ... more details

In information technology , the Datagram Transport Layer Security DTLS protocol provides communications privacy for packet information technology datagram protocols. DTLS allows datagram based applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. The DTLS protocol is based on the stream oriented Transport Layer Security TLS protocol and is intended to provide similar security guarantees. The datagram semantics of the underlying transport are preserved by the DTLS protocol the application will not suffer from the delays associated with stream protocols, but will have to deal with packet reordering, loss of datagram and data larger than a datagram packet size. DTLS is defined in RFC 6347 for use with User DatagramProtocol UDP , in RFC 5238 for use with DCCP , and in RFC 6083 for use with SCTP encapsulation.

IPstack The Time Protocol is a network protocol in the Internet Protocol Suite defined in 1983 in RFC 868. Its purpose is to provide a site independent, machine readable date and time. The Time Protocol may be implemented over the Transmission Control Protocol TCP or the User DatagramProtocol UDP . A host connects to a server that supports the Time Protocol on port 37. The server then sends the time as a 32 bit unsigned integer in binary format and in network byte order , representing the number of seconds since 00 00 midnight 1 January, 1900 GMT, and closes the connection. Operation over UDP requires the sending of any datagram to the server port, as there is no connection setup for UDP. The fixed 32 bit data format means that the timestamp rolls over approximately every 136 years, with the first such occurrence on 7 February 2036. Programs that use the Time Protocol must be carefully designed to use context dependent information to distinguish these dates from those in 1900. Many Unix like operating systems used the Time Protocol to monitor and or synchronize their clocks using the rdate utility, but this functionality was superseded by the Network Time Protocol NTP and the corresponding ntpdate utility, which report times with sub second accuracy and accounts for clock drift automatically. Inetd implementation On most UNIX like operating systems a Time Protocol server is built into the inetd or xinetd daemon computer software daemon . The service is usually not enabled by default.
