Interworking ● Problem: Interworking! ● Simultaneously to the ARPANET other (smaller) networks were developed ● All the LANs, MANs, WANs, ... ● had different protocols, media, ... ● could not be interconnected at first and were not be able to communicate with each other ● Therefore: ● Development of uniform protocols on the transport- and network level ● without a too accurate definition of these levels, in particular without exact coordination with the respective OSI levels ● Result: TCP/IP networks Univ.-Prof. Dr.-Ing. Jochen H. Schiller ▪ cst.mi.fu-berlin.de ▪ Telematics ▪ Chapter 6: Network Layer 6.26
TCP/IP ● Developed 1974: ● Transmission Control Protocol/Internet Protocol (TCP/IP) ● Requirements: ● Fault tolerance ● Maximum possible reliability and availability ● Flexibility, i.e., suitability for applications with very different requirements ● The result: ● Network protocol ● Internet Protocol (IP), connectionless ● End-to-end protocols ● Transmission Control Protocol (TCP), connection-oriented ● User Datagram Protocol (UDP), connectionless Univ.-Prof. Dr.-Ing.
