OSI model. SOCKS. SOCKS performs at Layer 5 of the OSI model (the session layer, an intermediate layer between the presentation layer and the transport layer).
History[edit] The protocol was originally developed/designed by David Koblas, a system administrator of MIPS Computer Systems. After MIPS was taken over by Silicon Graphics in 1992, Koblas presented a paper on SOCKS at that year's Usenix Security Symposium, making SOCKS publicly available.[1] The protocol was extended to version 4 by Ying-Da Lee of NEC. The SOCKS reference architecture and client are owned by Permeo Technologies,[2] a spin-off from NEC. Category:Application layer protocols. This category includes protocols from the Application Layer of the Internet Protocol Suite as well as the protocols of OSI Layer 7.
The Application Layer of the Internet Protocol Suite includes Session Layer protocols and Presentation Layer protocols from OSI.

Web services protocol stack. SOAP. Characteristics[edit] SOAP can form the foundation layer of a web services protocol stack, providing a basic messaging framework upon which web services can be built.
This XML-based protocol consists of three parts: an envelope, which defines what is in the message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing procedure calls and responses. SOAP has three major characteristics: extensibility (security and WS-routing are among the extensions under development), neutrality (SOAP can be used over any transport protocol such as HTTP, SMTP, TCP, UDP, or JMS), and independence (SOAP allows for any programming model). Network packet. Packet framing[edit] Different communications protocols use different conventions for distinguishing between the elements and for formatting the data.
In Binary Synchronous Transmission, the packet is formatted in 8-bit bytes, and special characters are used to delimit the different elements. Other protocols, like Ethernet, establish the start of the header and data elements by their location relative to the start of the packet. Internet Protocol. This article is about the IP network protocol only.
For Internet architecture or other protocols, see Internet protocol suite. The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. Secure Shell. Secure Shell (SSH) is a cryptographic network protocol for secure data communication, remote command-line login, remote command execution, and other secure network services between two networked computers.
It connects, via a secure channel over an insecure network, a server and a client running SSH server and SSH client programs, respectively.[1] The protocol specification distinguishes between two major versions that are referred to as SSH-1 and SSH-2. The best-known application of the protocol is for access to shell accounts on Unix-like operating systems, but it can also be used in a similar fashion for accounts on Windows.
Definition[edit] SSH uses public-key cryptography to authenticate the remote computer and allow it to authenticate the user, if necessary.[1] There are several ways to use SSH; one is to use automatically generated public-private key pairs to simply encrypt a network connection, and then use password authentication to log on.

Internet protocol suite. The Internet protocol suite is the computer networking model and set of communications protocols used on the Internet and similar computer networks.
It is commonly known as TCP/IP, because its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP), were the first networking protocols defined in this standard. Often also called the Internet model, it was originally also known as the DoD model, because the development of the networking model was funded by DARPA, an agency of the United States Department of Defense.
TCP/IP provides end-to-end connectivity specifying how data should be packetized, addressed, transmitted, routed and received at the destination. Session Initiation Protocol. SIP works in conjunction with several other application layer protocols that identify and carry the session media.
XSLT. XSLT (Extensible Stylesheet Language Transformations) is a language for transforming XML documents into other XML documents,[1] or other objects such as HTML for web pages, plain text or into XSL Formatting Objects which can then be converted to PDF, PostScript and PNG.[2] The original document is not changed; rather, a new document is created based on the content of an existing one.[3] Typically, input documents are XML files, but anything from which the processor can build an XQuery and XPath Data Model can be used, for example relational database tables, or geographical information systems.[1] XSLT is a Turing-complete language, meaning it can specify any computation that can be performed by a computer.[4][5] History[edit]
XHTML. XHTML (Extensible HyperText Markup Language) is a family of XML markup languages that mirror or extend versions of the widely used Hypertext Markup Language (HTML), the language in which web pages are written. While HTML (prior to HTML5) was defined as an application of Standard Generalized Markup Language (SGML), a very flexible markup language framework, XHTML is an application of XML, a more restrictive subset of SGML. Because XHTML documents need to be well-formed, they can be parsed using standard XML parsers—unlike HTML, which requires a lenient HTML-specific parser. XHTML 1.0 became a World Wide Web Consortium (W3C) Recommendation on January 26, 2000. XHTML 1.1 became a W3C Recommendation on May 31, 2001. Middleware. Middleware is computer software that provides services to software applications beyond those available from the operating system. It can be described as "software glue".[1] Middleware makes it easier for software developers to perform communication and input/output, so they can focus on the specific purpose of their application.
Middleware in distributed applications[edit] Software architecture: Middleware The term is most commonly used for software that enables communication and management of data in distributed applications. Distributed computing. "Distributed Information Processing" redirects here. For the computer company, see DIP Research. IRC reviews. Resource Description Framework. The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications[1] originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax notations and data serialization formats. It is also used in knowledge management applications. RDF was adopted as a W3C recommendation in 1999. The RDF 1.0 specification was published in 2004, the RDF 1.1 specification in 2014.
Overview[edit] RDF is an abstract model with several serialization formats (i.e. file formats), so the particular encoding for resources or triples varies from format to format. Semantic Web.
