INTERNET ARCHITECTURE

Its authors created architecture for connecting independent networks into seamless whole to federal, without any of the major networks. This was the advent of the Internet as we know it today. To work properly, the architecture of the global mechanism for responding (or Internet address) of computers in the network can invoke and communicate with computers on another network in the Federation. Internet addresses fill essentially the same role as telephone numbers in telephone networks. The design of the Internet is supposed first that the networks can not be changed, new architectural requirements for accommodation, but this is largely a pragmatic acceptance to facilitate progress. Networks have varying degrees of reliability and speed. Host computers will need to be able to upset packages to sit back in the right order and discard duplicate packets generated on the road. It was a big change from the virtual circuit similar services provided by the ARPANET and then this commercial network data services Tymnet and Telenet. In these networks, core network responsible for keeping all information is accurate and retransmission of information that could be lost. Computers Internet design, which are responsible for this trend to network problems. Basic architectural construction, introduction of portals (now called routers) between the networks of other treatments such as different bandwidth, packet sizes, error conditions and your requirements. The port will verify addresses Internet destination of each packet the door to what must be sent to fix. These functions will be combined with certain characteristics, end-end reliable communications production from source to destination. Draft paper the authors describe this approach was given at a meeting of the International Network Working Group in 1973 in Sussex, England and the final report was subsequently published by the Institute of Electrical and Electronic Engineers, the leading professional association for electrical engineering profession in its transactions Communications May, 1974 [VII]. The document describes the TCP / IP protocol. DARPA contracted with Cerf is a group at Stanford for a first working draft of the software TCP and soon after, with BBN and University College London independent implementation of the TCP-building (as they were called - was later split into TCP and IP) for different machines. BBN has a contract with a prototype version of the port to build. These three places in the development and testing of the initial reports on different machines. Cerf, then a professor at Stanford, provided the day to day leadership in the initial TCP software design and testing. BBN deployment of gateways between the ARPANET and PRNET and Satnet. During this period, including the overall management Cannes is DARPA, the initial feasibility of the architecture of the Internet proved.
