IPstack The Daytime Protocol is a service in the Internet Protocol Suite , defined in 1983 in RFC 867. It is intended for testing and measurement purposes in computer network s. A host may connect to a server that supports the Daytime Protocol on either Transmission Control Protocol TCP or User Datagram Protocol UDP port 13. The server returns an ASCII character string of the current date and time in an unspecified format. Inetd implementation On UNIX like operating systems a daytime server is usually 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 telling inetd to reload its configuration daytime stream tcp nowait root internal daytime dgram udp wait root internal An example output may be Tuesday, February 22, 1982 18 45 59 PST See also List of well known ports computing List of well known ports Echo Protocol Time Protocol Network Time Protocol External links RFC 867 http tf.nist.gov tf cgi servers.cgi List of NIST time servers supporting this protocol Category Network time related software Category Internet protocols Category Application layer protocols de Daytime es Daytime nl Daytime zh DAYTIME ... more details

IP is the primary protocol in the Internet Layer of the Internet Protocol ... datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974, the other being the connection oriented Transmission Control Protocol TCP .

Its successor is IPv6 Internet Protocol Version 6 IPv6 , which is increasing in use. Function The Internet Protocol is responsible ... across one or more IP networks. For this purpose the Internet Protocol defines an addressing system that has two functions identifying hosts and providing a logical location service.

Protocol spoofing is used in data communications to improve performance in situations where an existing Protocol computing protocol is inadequate, for example due to long delays or high error rates. Note In a computer security context, spoofing refers to various forms of falsification of data that are unrelated to the techniques discussed here. See spoofing attack . Spoofing techniques In most applications of protocol spoofing, a communications device such as a modem or router computing router simulates spoofs the remote endpoint of a connection to a locally attached host, while using a more appropriate protocol to communicate with a compatible remote device that performs the equivalent spoof at the other end of the communications link. File transfer spoofing Error correction and file transfer protocols typically work by calculating a checksum or CRC for a block of data known as a packet , and transmitting the resulting number at the end of the packet. At the other end the receiver re calculates the number and compares it to what was sent from the remote machine. If the two match the packet was transmitted correctly, and the receiver sends an tt ACK tt to signal that it s ready to receive the next packet. The time to transmit the tt ACK tt back to the sender is a function of the phone lines, as opposed to the modem s speed, and is typically about 1 10 of a second.

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 .

Computer network s use a tunneling protocol when one network protocol the delivery protocol encapsulation networking encapsulates a different payload protocol . By using tunneling one can for example carry a payload over an incompatible delivery network, or provide a secure path through an untrusted network. Tunneling typically contrasts with a layered protocol model such as those of Open Systems Interconnection OSI or TCP IP . The delivery protocol usually but not always operates at a higher level in the model than does the payload protocol, or at the same level. To understand a particular protocol stack, network engineers must understand both the payload and delivery protocol sets.

Known defects in prior protocols must be corrected. Inexpensive. Implementation cost must be low. Based on Meiners experience and reading the literature, he believed Zmodem The ideal protocol. Highly reliable and fast. Only failing is that the cost of implementation is high. Ymodem Very fast, but not network friendly. Also leaves something to be desired on the reliability front. Error correction is slow. WXmodem Fast and network friendly. However, several questions exist with regard to reliability.

Unreferenced date December 2009 Orphan date December 2009 In telephony , a stimulus protocol is a type of protocol that is used to carry event notifications between end points. Such a protocol is used to control the operation of devices at each end of the link. However a stimulus protocol is not sensitive to the system state. In a typical application such a protocol will carry keystroke information from a telephone set to a central call control . It may also carry control information for simple types of text displays. MiNET from Mitel is a typical protocol of this sort. Stimulus protocols are most suited to networks with dumb peripherals and intelligent centralized applications see intelligent network . This is in contrast to functional protocols which are best suited to a network with an intelligent periphery and a dumb core see dumb network . Because these architectures share core hardware over large numbers of peripherals, large and expensive computing capabilities in terms of both hardware and software may be supplied. These centralized architectures excel in solving the problems of complexity for large scale applications since the investment in hardware and software may be amortized across a great many users. However the same virtue of large scale sharing prevents these architectures from providing any significant degree of customization to the preferences of the individual user. The most that can be supplied is a degree of parameterization of service operation. With their suitability tied to the virtues of centralized network architectures, stimulus protocols are being deprecated in favor of functional protocols with the rise of the Internet. A functional protocol such as Session Initiation Protocol SIP from the IETF is more suited for Internet applications.
