Internetworking Technology Handbook is a free online book by Cisco and it covers many topics related to internetworking technologies. An internetwork is a collection of individual networks, connected by intermediate networking devices, that functions as a single large network.
Internetworking refers to the industry, products, and procedures that meet the challenge of creating and administering internetworks.The first networks were time-sharing networks that used mainframes and attached terminals. Such environments were implemented by both IBM’s Systems Network Architecture (SNA) and Digital’s network architecture.
Local-area networks (LANs) evolved around the PC revolution. LANs enabled multiple users in a relatively small geographical area to exchange files and messages, as well as access shared resources such as file servers and printers.
Wide-area networks (WANs) interconnect LANs with geographically dispersed users to create connectivity. Some of the technologies used for connecting LANs include T1, T3, ATM, ISDN, ADSL, Frame Relay, radio links, and others. New methods of connecting dispersed LANs are appearing everyday.
Today, high-speed LANs and switched internetworks are becoming widely used, largely because they operate at very high speeds and support such high-bandwidth applications as multimedia and videoconferencing.
Internetworking evolved as a solution to three key problems: isolated LANs, duplication of resources, and a lack of network management. Isolated LANs made electronic communication between different offices or departments impossible. Duplication of resources meant that the same hardware and software had to be supplied to each office or department, as did separate support staff. This lack of network management meant that no centralized method of managing and troubleshooting networks existed.
