7. Higher order protocols such as UDP TCP IP need to be used in any case if an Ethernet network has to be connected with multiple networks ircam Centre Appendice B Network basics Pompidou UDP TCP IP the most important protocols As far back as the 1960 s the American military gave out the assignment of creating a protocol which would enable a standardized exchange of information between any number of various networks regardless of the hard and software used The result of specification was TCP IP protocol which was introduced in 1974 Although TCP and IP are always named together they are really two complementary protocols The Internet protocol IP takes over the actual addressing and delivery of the data packets while the overlying Transport Control Protocol TCP is responsible for transporting the data and making it secure UDP is another transport protocol which like TCP lives above IP But in contrast to TCP UDP is connectionless Each data packet is treated like a separate mailing and there is no confirmation as to whether a packet was received IP Internet Protocol Internet Protocol makes it possible to assemble an indefinite number of individual networks into an overall network This means it enables data exchange between any two network stations located respectively in any given individual network The physical implementation of the networks and transmission paths Ethernet token ring ISDN is immaterial here
