IPstack The Echo Protocol is a service in the Internet Protocol Suite defined in RFC 862. It was originally proposed for testing and measurement of round trip times Citation needed date November 2009 in IP networks. A host may connect to a server that supports the Echo Protocol using the Transmission Control Protocol TCP or the User Datagram Protocol UDP on the List of well known ports computing well known port number 7. The server sends back an identical copy of the data it received. The functionality of the Echo Protocol was superseded by the echo request of the Internet Control Message Protocol and the corresponding ping utility. Inetd implementation On UNIX like operating systems an echo server is built into the inetd daemon computer software daemon . The echo service is usually not enabled by default. It may be enabled by adding the following lines to the file tt etc inetd.conf tt and telling inetd to reload its configuration echo stream tcp nowait root internal echo dgram udp wait root internal See also Discard Protocol Daytime Protocol Character Generator Protocol Time Protocol External links RFC 347 Echo Process RFC 862 Echo Protocol Category Internet protocols Category Application layer protocols cs ECHO protocol da Echo protokol de Echo Netzwerkdienst ... more details
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 Datagram Protocol 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used the Time Protocol to monitor and or synchronize their clocks using the rdate utility, but this functionality was superseded by the Network Time Protocol NTP and the corresponding ntpdate utility, which report times with sub second accuracy and accounts for clock drift automatically.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. It may be enabled by adding the following lines to the file tt etc inetd.conf tt and reloading the configuration. time stream tcp nowait root internal time dgram udp wait root internal See also Echo Protocol Discard Protocol Daytime Protocol Character Generator Protocol rdate , a tool for querying ...

Protocol overhead refers to metadata and network routing information sent by an computer application application , which uses a portion of the available Bandwidth computing bandwidth of a communications protocol . This extra data, making up the protocol headers and application specific information is referred to as overhead, since it does not contribute to the content of the message. Protocol overhead can be expressed as a percentage of non application byte s protocol and frame synchronization divided by the total number of bytes in the message.

IPstack The Discard Protocol is a service in the Internet Protocol Suite defined in RFC 863. It is intended for testing, debugging, and measurement purposes. A host may send data to a host that supports the Discard Protocol on either Transmission Control Protocol TCP or User Datagram Protocol UDP port number 9. The data sent to the server is simply discarded. No response is returned. Inetd implementation On most UNIX like operating systems a discard server is built into the inetd or xinetd daemon computer software daemon . The discard service is usually not enabled by default. It may be enabled by adding the following lines to the file tt etc inetd.conf tt and reloading the configuration discard stream tcp nowait root internal discard dgram udp wait root internal The Discard Protocol is the TCP UDP equivalent of the Unix filesystem node dev null .

A binary protocol is a network protocolprotocol which is intended or expected to be read by a machine rather than a human being, as opposed to a plain text protocol such as IRC , SMTP , or HTTP . Binary protocols have the advantage of terseness, which translates into speed of transmission and interpretation. There has always been tension between two software development camps that believe new protocols should preferably be text based or binary, respectively. In recent years, with the ready availability of network bandwidth and mass storage, the text based camp has been gaining significant ground XML based systems are nearly ubiquitous but the debate continues ref http www.webservices.org weblog mark little soap for the masses A representative discussion of text and binary protocol debate, by Mark Little ref . Binary protocol is also used in the context of a protocol between exactly two parties, in contrast to a multi party protocol. Binary protocol, or binary collaboration have been used in the terminology of standards such as EbXML and EDOC ref http www.omg.org technology documents formal edoc.htm EDOC ref . An interface in the UML ref http www.uml.org Unified Modeling Language ref may also be considered a binary protocol.

orphan date January 2011 Protocol Builder is a tool in some programming language s like C and C Sharp programming language C to generate code to build Communications protocolprotocol s in a fast and reliable way. Network programming for all kinds of protocols like Transmission Control Protocol TCP , User Datagram Protocol UDP , SNMP ... includes converting data to be transferred to a raw byte s in the sending side and parsing these bytes in the receiving side. Protocol builders facilitate this stage usually by generating the code automatically. Protocol Programming has many components to be developed, these are server listener, server connection, client connection, packets, and loggers, most protocol builders implement these components automatically so developers save time and money. Currently, there are two Protocol Builders in the market, one for C from UpRedSun which is for TCP and UDP protocols. The Second one is for .NET Framework .Net languages which generates the code in C for TCP Protocols, this tool is called .Net Protocol Builder.

Orphan date February 2009 The swIPe IP Security Protocol swIPe is an experimental Internet Protocol IP security Protocol computing protocol that was specified in 1993. It operates at the Internet Layer of the Internet Protocol Suite . Purpose swIPe provides confidentiality, integrity, and authentication of network traffic, and can be used to provide both end to end and intermediate hop security. swIPe is concerned only with security mechanisms. The protocol does not handle policy and key management, which are handled outside the protocol.
