The Simple Mail Transfer Protocol (SMTP) is a communication protocol for electronic mail transmission. As an Internet standard, SMTP was first defined in 1982 by RFC 821, and updated in 2008 by RFC 5321 to Extended SMTP additions, which is the protocol variety in widespread use today. Mail servers and other message transfer agents use SMTP to send and receive mail messages. Proprietary systems such as Microsoft Exchange and IBM Notes and webmail systems such as Outlook.com, Gmail and Yahoo! Mail may use non-standard protocols internally, but all use SMTP when sending to or receiving email from outside their own systems. SMTP servers commonly use the Transmission Control Protocol on port number 25.
SOAP is a messaging protocol specification for exchanging structured information in the implementation of web services in computer networks. Its purpose is to provide extensibility, neutrality and independence. It uses XML Information Set for its message format, and relies on application layer protocols, most often Hypertext Transfer Protocol (HTTP) or Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission.
The Transmission Control Protocol (TCP) is one of the main protocols of the Internet protocol suite. It originated in the initial network implementation in which it complemented the Internet Protocol (IP). Therefore, the entire suite is commonly referred to as TCP/IP. TCP provides reliable, ordered, and error-checked delivery of a stream of octets (bytes) between applications running on hosts communicating via an IP network. Major internet applications such as the World Wide Web, email, remote administration, and file transfer rely on TCP. Applications that do not require reliable data stream service may use the User Datagram Protocol (UDP), which provides a connectionless datagram service that emphasizes reduced latency over reliability.
The Society for Worldwide Interbank Financial Telecommunication (SWIFT) provides a network that enables financial institutions worldwide to send and receive information about financial transactions in a secure, standardized and reliable environment. SWIFT also sells software and services to financial institutions, much of it for use on the SWIFTNet network, and ISO 9362. Business Identifier Codes are popularly known as "SWIFT codes".
The term Web service (WS) is either:
Direct Client-to-Client (DCC) is an IRC-related sub-protocol enabling peers to interconnect using an IRC server for handshaking in order to exchange files or perform non-relayed chats. Once established, a typical DCC session runs independently from the IRC server. Originally designed to be used with ircII it is now supported by many IRC clients. Some peer-to-peer clients on napster-protocol servers also have DCC send/get capability, including TekNap, SunshineUN and Lopster. A variation of the DCC protocol called SDCC, also known as DCC SCHAT supports encrypted connections. An RFC specification on the use of DCC does not exist.
Two-way communication is a form of transmission in which both parties involved transmit information. Two-way communication has also been referred to as interpersonal communication. Common forms of two-way communication are:
Message-oriented middleware (MOM) is software or hardware infrastructure supporting sending and receiving messages between distributed systems. MOM allows application modules to be distributed over heterogeneous platforms and reduces the complexity of developing applications that span multiple operating systems and network protocols. The middleware creates a distributed communications layer that insulates the application developer from the details of the various operating systems and network interfaces. APIs that extend across diverse platforms and networks are typically provided by MOM.
Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email. SPF alone though is limited only to detect a forged sender claimed in the envelope of the mail which is used when the mail gets bounced. Only in combination with DMARC it can be used to detect forging of the visible sender in emails, a technique often used in phishing and email spam.
The Resource Reservation Protocol (RSVP) is a transport layer protocol designed to reserve resources across a network for quality of service (QoS) using the integrated services model. RSVP operates over an IPv4 or IPv6 and provides receiver-initiated setup of resource reservations for multicast or unicast data flows. It does not transport application data but is similar to a control protocol, like Internet Control Message Protocol (ICMP) or Internet Group Management Protocol (IGMP). RSVP is described in RFC 2205.
Wire transfer, bank transfer or credit transfer is a method of electronic funds transfer from one person or entity to another. A wire transfer can be made from one bank account to another bank account or through a transfer of cash at a cash office.
The RTP Control Protocol (RTCP) is a sister protocol of the Real-time Transport Protocol (RTP). Its basic functionality and packet structure is defined in RFC 3550. RTCP provides out-of-band statistics and control information for an RTP session. It partners with RTP in the delivery and packaging of multimedia data, but does not transport any media data itself.
In game theory, a signaling game is a simple type of a dynamic Bayesian game.
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. It provides a mechanism for the receiver to control the transmission speed, so that the receiving node is not overwhelmed with data from transmitting node. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred. Flow control mechanisms can be classified by whether or not the receiving node sends feedback to the sending node.
In finance, market data is price and trade-related data for a financial instrument reported by a trading venue such as a stock exchange. Market data allows traders and investors to know the latest price and see historical trends for instruments such as equities, fixed-income products, derivatives, and currencies.
Bilateral Key Exchange (BKE) was an encryption scheme utilized by The Society for Worldwide Interbank Financial Telecommunications (SWIFT).
Group Domain of Interpretation or GDOI is a cryptographic protocol for group key management. The GDOI protocol is specified in an IETF Standard, RFC 6407, and is based on Internet Security Association and Key Management Protocol (ISAKMP), RFC 2408, and Internet Key Exchange version 1 (IKE). Whereas IKE is run between two peers to establish a "pair-wise security association", GDOI protocol is run between a group member and a "group controller/key server" (controller) and establishes a security association among two or more group members.
The telex network was a public switched network of teleprinters similar to a telephone network, for the purposes of sending text-based messages. Telex was a major method of sending written messages electronically between businesses in the post-World War II period. Its usage went into decline as the fax machine grew in popularity in the 1980s.
The Cross-Border Interbank Payment System (CIPS) is a payment system which offers clearing and settlement services for its participants in cross-border RMB payments and trade. It is a significant financial market infrastructure in China. As planned, CIPS will be developed in two phases. On 8 October 2015, CIPS went live. The first batch of direct participants includes 19 Chinese and foreign banks which were set up in mainland China and 176 indirect participants which cover 6 continents and 47 countries and regions. On 25 March 2016, CIPS signed an MoU with SWIFT with mutual understanding of deploying SWIFT as a secure, efficient and reliable communication channel for CIPS's connection with SWIFT's members, which would provide a network that enables financial institutions worldwide to send and receive information about financial transactions in a secure, standardised and reliable environment. CIPS is sometimes referred to as the China Interbank Payment System.
Linked Data Notifications (LDN) is a W3C Recommendation that describes a communications protocol based on HTTP, URI, and RDF on how servers (receivers) can receive messages pushed to them by applications (senders), as well as how other applications (consumers) may retrieve those messages. Any web resource can advertise a receiving endpoint (inbox) for notification messages. Messages are expressed in RDF, and can contain arbitrary data.
