TCP/IP: Explored and Explained

TCP / IP is not a single protocol, as well as his, as the name suggests a pair of protocols. TCP / IP is actually a set of protocols. In other words, it is a large group of protocols that work together. TCP / IP designers original intent to establish a protocol can deny that the various heterogeneous network without the ability to take multiple routes to the final destination. This flexibility is important. TCP / IP, originally called NCP (Network Control Protocol), is the product of a pilot project for the Ministry of Defense of ARPANET (Advanced Research Project Agency Network) as an experimental protocol, which traveled over packet switching networks. The aim is that if one part of the network has become damaged or inaccessible, the transfer of critical data will continue to reach its destination on the network via alternate routes.

Despite its roots in the defense community, the development and evolution of TCP / IP can not be attributed to any one group of people. TCP / IP is a generic, and it took in the communications protocol for the Internet. As in other matters related to Internet, TCP / IP standards of transparency and published as RFCs (Request for Comments), which are maintained by the Internet Architecture Board (IAB).

In the IAB allow any person or company, or to assess in the RFC. RFCs can contain a variety of information, one using the RFCs is to publish the proposals or ideas, new standards, which can add or change the functionality of TCP / IP protocol suite in a way. RFCs are available on the Internet for public review and discusses the IETF (Internet Engineering Task Force), a division of IAB. After the appropriate amount of discussion and study, recently proposed by the project can be made into a standard, which will then be adopted for the entire web development community. Because the TCP / IP through an open, generic standards, it has been thoroughly revised and many people from all over the world, and thus constantly evolve and improve since its inception.

TCP / IP based on the idea of an open system (generic) model. With respect to system architecture, TCP / IP S functionality maps freely OSI (open systems interconnection) reference model, a basic system architecture is a reference for programmers, to ensure a common framework for the development of network protocols. Using the OSI model, protocol designers can ensure that their design meets the protocol at least basic levels of functionality and that there is some degree of standardization between them and someone elses protocol. Microsoft TCP / IP line with the published RFC-TCP / IP standards. Nevertheless, Microsoft implementation includes support for a number of features not found in other versions of TCP / IP.

Requests for Comments (RFCs)

As mentioned earlier, one of the methods used by RFCs is a document standard. Note that the RFCs that actually document the standards are only a subset of all RFCs that exist. In other words, all the Internet standards are described at least in the RFC, but not all RFCs become standards.

In a number of different types of RFCs exist, including FYIs, Drafts and STD (standard). Any person may file an RFC or make comments for or against, the current RFC. In the IETF and the documents available to the public. If the RFC is a proposal for a new Internet protocol or service, it is considered in the IETF, and recommendations for changes are made. To ensure adequate time for study and revision in the RFC, there is a minimum six-month waiting period before the proposed standard could become a draft standard that is still four months before the draft standard could become standard.

RFC are references to specific numbers, for example, RFC 1880 Internet Official Protocol Standards. These numbers are issued sequentially and never reused. If the current standard is revised, the new number is issued to the revised standard, but an earlier version has become obsolete. Always make sure you have the most recent RFC on any topic you study. RFC 1880, for example, contains a pointer to the latest RFCs Web standards. To find a specific RFC, or learn more about the RFCs in general, you can visit in the InterNIC or one of the many search engines available on the website, such as Search.Com at, and search RFC .
