Abstract

Describes a layer model for networks. For each layer, one or more services are defined, and for each service a protocol is specified. 2 OSI application level protocols have been defined for library services: SR and ILL. The underlying layers are supposed to be OSI services, but some implementations are using TCP/IP, and some are using a mixture of OSI and TCP/IP. The systems based directly on TCP/IP can not communicate with those based purely on OSI. Discusses the pros and cons for choosing OSI or TCP/IP. Gateways between the OSI and TCP/IP networks are needed. The ISO protocol SR and the ANSI protocol Z39.50 are both 'search and retrieve' protocols. The SR is almost a subst of Z39.50, but they may become identical in the future. There is only one protocol for interlibrary loan, the ISO ILL protocol. It covers 3 models of interlibrary loan and all services connected with ILL. Other services such as Explain, Scan and Update are presently being discussed in ISO TC 46. Discusses the needs of the library community for network services such as file transfer, remote login, directories and electronic mail
