refimprove date January 2009 FileServiceProtocol FSP is a User Datagram Protocol UDP based replacement for the File Transfer Protocol , designed for anonymous access with lower hardware and network requirements than FTP. In particular, because it uses UDP, it avoids the problems that many FTP servers have had with requiring a separate process for each client, and because it is built to use an unreliable protocol, it can more easily handle resuming a transfer after a network failure. History FSP never reached the popularity of FTP for legitimate use although WU FTPD wuarchive and id Software provided FSP service in addition to FTP for some time , but became very popular in the early to mid 1990s for Darknet file sharing underground sites containing pornography and or warez .

Refimprove date March 2010 IPstack File eXchange Protocol FXP and FXSP is a method of data transfer which uses File Transfer Protocol FTP to transfer data from one remote server to another inter server without routing this data through the client s connection. Conventional FTP involves a single Server computing server and a single client computing client all data transmission is done between these two. In the FXP session, a client maintains a standard FTP connection to two servers, and can direct either server to connect to the other to initiate a data transfer. The advantage of using FXP over FTP is evident when a high bandwidth server demands resources from another high bandwidth server, but only a low bandwidth client, such as a network administrator working away from location, has the authority ...

In computing , Multisource File Transfer Protocol MFTP is designed for the purpose of file sharing . It is still under development, and therefore may acquire more features or other improvements in addition to those discussed in this article. This is the communication protocol used by such clients as eMule and eDonkey and, in its extended implementation, by the Overnet network. Features Strengths In addition to being able to search by filename, MFTP is able to uniquely identify files based on their contents, regardless of how they are named on each individual computer. It also has bandwidth management also known as leech resistance built into the protocol, and every known mature client allows the user to tweak file and user upload priorities. It is also possible to share Metadata computing metadata about a given file with links on Web sites such as this file is good, this file is corrupted, this file is not what the name may indicate in this case, the files are identified with their MD4 Hash function hash numbers which are consistent rather than their filenames which will often vary from one computer to the next . The Protocol computing protocol is still under development, so additional features and other improvements are still possible. There are several unique forks of the protocol eDonkey2000 implemented what it called hoarding of sources, eMule uses a credit system, and xMule has extended the credit system to facilitate in the transfer of rare files. It has recently when date April 2011 been announced that MFTP had been used successfully in Internet2 project, achieving excellent results in terms of speed and reliability when transferring or sharing files.

As servers are booted up, they may advertise their services using SAP when they are brought down, they use SAP to indicate that their services will no longer be available. IPX network servers may use SAP to identify themselves by name and service type.

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.

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.

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 ...
