These systems used proprietary networking architectures and protocols, consisting primarily of plugging dumb terminals or line printers into an intelligent communications controller. Each of these devices used proprietary networking protocols to communicate with the central host. ƒ These computer systems used proprietary design, products, protocols, and services to interconnect. ƒ Companies expanded their existing networks by purchasing more of the same type of equipment. ƒ Cross-platform connectivity did not exist and was not expected. Interworking between organizations ƒ Interworking between vendors first occurred when the US Military realized that different sites around the country could not connect with each other because they all ran proprietary systems and protocols. ƒ Without cross-platform support, effective communication or resource sharing between sites was not possible. This could become critical in the event of a national disaster, or more commonly, equipment failure where the inability to transfer resources or to backup information could leave that information unprotected. Scalable IP Networks v2.00 Module 1 - 5 Alcatel-Lucent Confidential for internal use only -- Do Not Distribute ƒ General interest in cross-platform connectivity was non-existent Significance of ARPANET ƒ Initial ARPANET consisted of: y Interface message processors (IMP) y Host computers connected to IMP via serial line ƒ Another network called ALOHANET funded by ARPA ƒ Other packet switched networks developed in Europe ƒ In 1972, INWG decided to connect all of these networks Alcatel-Lucent Scalable IP Networks v2.00 Module 1 | 6 All rights reserved © 2008 Alcatel-Lucent Cross-organizational communications ƒ The project to enable cross-organizational communications was initiated by ARPA of the DoD. The priority for this project was vendor-independent networking. As a result, the world’s first packet switched network, ARPANET, was conceived. ƒ ARPANET was initially deployed between four sites (Stanford University, University of California at Santa Barbara, University of California at Los Angeles, and University of Utah). It was designed with reliability in mind and consisted of redundant packet switches, links, and a dynamic routing protocol. ƒ In 1969, ARPA funded an experimental packet radio network at the University of Hawaii. This network, ALOHANET was directed by Professor Norman Abramson, and connected sites that were spread throughout the Hawaiian islands to a central time-sharing computer on the University of Hawaii campus. ƒ ALOHANET users could connect to the ARPANET. However, this access through the terminal interface processor (TIP) meant that, from the ARPANET perspective, ALOHANET was just a terminal connection. ƒ Dr. Robert Kahn, one of the BBN IMP researchers who was instrumental in developing the IMP-to-host protocol, architecting the ARPANET, and improving its reliability, organized an event to demonstrate ARPANET. During this event, a new working group called the International Network Working Group (INWG), was organized. One of the tasks that INWG undertook was to connect ARPANET and ALOHANET to some of the new packet switching European networks to create a Giant Global network. Kahn began a lengthy series of discussions with Vint Cerf, the INWG chairman, to find a solution. ƒ Their model was an internetworking of the ARPANET with a packet radio network and a satellite network (SATNET)—each of which used different protocols and different interfaces, and were optimized for each particular network's needs. Scalable IP Networks v2.00 Module 1 - 6 Alcatel-Lucent Confidential for internal use only -- Do Not Distribute y Host-to-host protocol called Network Control Protocol (NCP) The Challenge of ARPANET Challenges ƒ ARPANET was designed for a very high degree of reliability, and NCP depended upon this level of reliability ƒ Addressing ƒ Each network had its own maximum packet sizes ƒ Kahn developed a new host-to-host protocol with global addressing ƒ In 1973, TCP was developed as a protocol to connect these networks Alcatel-Lucent Scalable IP Networks v2.00 Module 1 | 7 All rights reserved © 2008 Alcatel-Lucent Challenges ƒ Packet radio and satellite links could not guarantee the same kind of reliability that was designed into ARPANET. ƒ NCP only supported local addressing to the next hop node. It did not provide the addressing plan that was required for a global network such as the Internet. ƒ Each network supported its own maximum packet size. When a packet traveled from one network to the next it may have needed to be broken into a number of smaller packets to traverse the next network. Solution ƒ The development of a new host-to-host protocol that supported global addressing, the ability to recover lost packets, perform fragmentation and reassembly, calculate end-to-end checksums, and provide host-to-host flow control. ƒ The first version of this new protocol was presented by Kahn and Cerf at a meeting of the INWG at Sussex University in the United Kingdom in September 1973. It was called the Transmission Control Protocol (TCP). ƒ In 1978, TCP evolved to become TCP/IP. TCP/IP The introduction and wide-scale deployment of TCP/IP represented a major shift in computer networking. Prior to TCP/IP, most network topologies required hardware-based network nodes to send traffic to a central host for processing with the central host delivering the data to the destination node on behalf of the sender. With the introduction of TCP/IP, each network device was treated as a fully functional, self-aware network endpoint, capable of communicating with any other device directly without using a central host.
