	Communications protocol - Wikipedia, the free encyclopedia
		In the field of telecommunications, a communications protocol is the set of standard rules for data representation, signalling, authentication and error detection required to send information over a communications channel.
		An example of a simple communications protocol adapted to voice communication is the case of a radio dispatcher talking to mobile stations.
		Protocol layering allows the parts of a protocol to be designed and tested without a combinatorial explosion of cases, keeping each design relatively simple.

	Communications Protocols (Site not responding. Last check: 2007-11-05)
		Protocols are normally defined in a layered manner and provide all or part of the services specified by a layer of the OSI reference model.
		Protocols are usually implemented by writing a number of programs (processes) which communicate with one another through queues and by function calls.
		Protocols are generally described using a layered architecture known as the OSI reference model.

	(Features) Communications-protocol testing: Balancing technology, planning, compliance (MEM archive, Oct 04)
		Communications software is unique in that the software for both sides of the communication needs to be working to fully exercise the software on either side (unless some type of simulation is used).
		More often than not, these devices are communications monitors, and, while useful for examining the communications traffic on the communications medium, they are typically limited in their ability to insert errors to test the handling on both sides of the communication.
		Communications interfaces in medical devices are notorious for their ability to defy traditional manual test efforts for exposing communication software defects.

	RFC 3304 (rfc3304) - Middlebox Communications (midcom) Protocol Requiremen (Site not responding. Last check: 2007-11-05)
		This states that the protocol must include mechanisms for avoiding race conditions or other situations in which the requests of one agent may influence the results of the requests of other agents in an unpredictable manner.
		This states that the protocol must provide clear identification for requests and results and that protocol operations must be atomic with respect to the midcom protocol.
		The protocol must support the concept of a ruleset group comprising a multiple of individual rulesets to be treated as an aggregate.

	Microsoft Communications Protocol Program
		Microsoft accordingly encourages developers interested in licensing the company's protocol technology for purposes other than described in the standard MCPP license agreement (for example initializing the Rights Management Services environment) to discuss their technical requirements with Microsoft's protocol licensing team so that a suitable solution can be worked out.
		Many of the protocols used by Windows 2000 and Windows XP client operating systems to interoperate or communicate with Microsoft server operating systems are available through standards organizations or are otherwise published and available from third-party sources.
		A royalty-free license for such published protocols is available from Microsoft for those who want to ensure that they have a license under any intellectual property rights Microsoft may have in any or all of those published protocols.

		Communications protocols are often sophisticated, involving a sequence of complex message exchanges.
		Known protocol analysers for testing communications protocols involve the use of data bases, which are pre-programmed with all possible combinations of messages sequences which correspond with the protocol to be tested.
		By using a neural network within the protocol analyser, a sequence of messages exchanged in accordance with a correctly operating communications protocol may be learned, obviating the need for a data base.

	RFC 4097 (rfc4097) - Middlebox Communications (MIDCOM) Protocol Evaluation (Site not responding. Last check: 2007-11-05)
		The protocol is designed as a base protocol in RFC 3588 [24] to be supported by all implementations, plus extensions devoted to specific applications.
		The protocol is also stateful in that it allows the server to push configuration information to the client, and then allows the server to remove such state from the client when it is no longer applicable.
		Protocol Machinery This section describes the compliancy of the proposed protocols against the protocol machinery requirements from section 2.1 of the requirements document [1].

	What is communications protocol? - A Word Definition From the Webopedia Computer Dictionary (Site not responding. Last check: 2007-11-05)
		All communications between devices require that the devices agree on the format of the data.
		These protocols are almost always implemented in the hardware; that is, they are built into modems.
		In addition to the standard protocols listed in the table, there are a number of protocols that complement these standards by adding additional functions such as file transfer capability, error detection and recovery, and data compression.

	FCP - Five-bit Communications Protocol
		The Five-bit Communications Protocol (FCP) is a method of communicating, similar to Baudot code, that uses two states (expressed as '1' and '0') to represent characters in fixed five-bit code sizes and which also defines a standard procedure for transmissions.
		This protocol is designed to be easily retained by humans in memory.
		This protocol can be used to communicate between two persons where there is some way to represent two distinct states (expressed as '1' and '0') to send the five-bit characters.

	PRESS RELEASE JCB and MasterCard Agree to Share Common Contactless Communications Protocol (Site not responding. Last check: 2007-11-05)
		Visa International made an announcement to support the protocol in March 2005, and JCB`s adoption of the specification means that these major international card brands will be basing their contactless payment applications on the same communications protocol.
		While contactless payment applications vary by brand, the common specification for communications protocol will allow POS terminal vendors to reduce the burden of system development, as well as reducing initial costs and lead time for most financial institutions and merchants because they do not have to purchase multiple POS terminals to support contactless card products.
		The common communication protocol ensures global interoperability for contactless payment products and as a result it is anticipated that the pace of deployment of contactless terminals will accelerate.

	WebRoom: InterMUD Communications Protocol with Extensions to VRMLize Multiuser Domains
		On the other hand, interactive Internet communication applications such as the MUD (Multiuser Domain/Dimension/Dungeon) provide a ready mechanism for stateful real-time communications in which the powerful hyperlinking concept of the WWW can be incorporated.
		We describe an implementation of this extended protocol using a prototype Web-browser MUD client incorporating the interactive characteristics of a MUD session with seamless MUD-to-MUD navigation, WWW document hyperlinking, and VRML 3-D rendering of MUD rooms.
		With VRML support in the IMC protocol, it is now possible for a person on the Internet to navigate from MUD room to MUD room, interacting with other people in the same room through a VRML world.

	User-Defined Communications
		A queue is used by the user-defined communications support to inform an application program of some action to perform or of an activity that is complete.
		Contrast this with Figure 1-3 which shows how much more of the protocol is defined by the user-defined communications application than by the APPC application.
		Because user-defined communications does not allow applications to define the data link and physical layers, the entire token-ring or Ethernet frame is not available to your applications.

	XON/XOFF Communications Protocol Not Supported in QuickBasic
		The XON/XOFF handshaking protocol of the ASC option of the OPEN COM statement is not implemented in any version of QuickBasic (including versions 2.00, 2.01, 3.00, 4.00, 4.00b, and 4.50), in Microsoft Basic Compiler version 6.00 or 6.00b for MS-DOS, or in Microsoft Basic Professional Development System (PDS) version 7.00 or 7.10 for MS-DOS.
		During communications, the ASC option expands tabs to spaces, forces carriage returns at the end-of-line, treats CTRL+Z (ASCII value 26) as the end-of-file flag, and transmits CTRL+Z when you CLOSE the communications channel.
		This behavior occurs because the XON/XOFF handshaking protocol of the ASC option of the OPEN COM statement is not implemented.

		Another is the time-honored tradition of blocking unauthorized clients from using your protocols, and then keep changing the blocking techniques as each one is worked around by the intruding client's own developers.
		But the communications protocol could be opened up and documented, maybe even with a supported official API.
		That would be a hit with trendsetting übergeeks, and eBay has a history of supporting outside developers, though it could cut into ad revenue.

	EETimes.com - Enea's Inter Process Communications protocol now open source
		On the agenda for discussion is a proposal by Wind River to standardize on the already existing Transparent IPC (TIPC) protocol, first developed by Ericsson for distributed applications in the telecommunications and networking environment.
		However, the transport protocols part of LINX is linked with the Linux kernel (as a kernel module) and therefore is licensed under the GPL.
		A key element in the new LINX open source protocol is the use of a unique address mapping model, in which the IPC nodes store only the addresses needed for local connections, and as a result require minimal memory for code/data storage, allowing easier on-the-fly reconfiguration.
