The OSI protocol suite (an internationally standardized set of rules for computer communications) offers a unique promise: it has the potential to provide a political and technical solution to world-wide networking. Computers--from supers to workstations and PCs, from the executive suite to the laboratory, and from Palo Alto to London, or anywhere--can all share a common set of rules for communicating. But, with any emerging technology, there are numerous questions to be answered and issues to be addressed. The Open Book is designed to examine those complex questions and issues and provide a balanced set of perspectives.
This is a book to be welcomed with relief, providing a refreshingly clear sighted and amused approach to a subject....recommended both as an introduction to the standards themselves and as a basis from which to look at the direction they are taking. If you are looking for more detailed information about the OSI upper layers in a comprehensible form, this is the book for you. It covers the transport, session, and presentation layers in their entirety, and parts of the applications layer, notably FTAM and MOTIS. The style is highly readable and numerous explanatory figures are provided.
