This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model. This list is not exclusive to only the OSI protocol family . Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Message delivery at the network layer is not necessarily guaranteed to be reliable; a network layer protocol may provide reliable message delivery, but it does not need to do so. A number of layer-management protocols, a function defined in the management annex, ISO 7498/4, belong to the network layer. These include routing protocols, multicast ...
Layer 4: transport layer [ edit ] The connection-mode and connectionless-mode transport services are specified by ITU-T Rec. X.214 [ISO/IEC 8072] ; the protocol that provides the connection-mode service is specified by ITU-T Rec. X.224 [ISO/IEC 8073] , and the protocol that provides the connectionless-mode service is specified by ITU-T Rec. X ...
A large portion of HL7 messaging is transported by Minimal Lower Layer Protocol (MLLP), also known as Lower Layer Protocol (LLP) [22] or Minimum Layer Protocol (MLP). [23] For transmitting via TCP/IP, header and trailer characters are added to the message to identify the beginning and ending of the message because TCP/IP is a continuous stream ...
IEEE 802.11 a/b/g/n are standards for implementing a wireless local area network (WLAN) in 2.4 GHz and 5 GHz frequency bands, utilizing the same basic protocol. [ citation needed ] Regulatory organizations and industrial associations, such as Integrating the Healthcare Enterprise (IHE) initiative and Continua Health Alliance , are working ...
IPX is a network-layer protocol (layer 3 of the OSI model), while SPX is a transport-layer protocol (layer 4 of the OSI model). The SPX layer sits on top of the IPX layer and provides connection-oriented services between two nodes on the network. SPX is used primarily by client–server applications. IPX and SPX both provide connection services ...
Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.
