Contemporary distributed file systems are monolithic and only support single file abstractions. Nowadays, as Sai-Lai Lo explains, network storage devices have to accommodate new information media such as digital audio and video, with data radically different from the traditional text and binary code that contemporary file systems are optimized for. In this book, the author shows how, by combining new and traditional media, information can be recorded and presented in the most suitable way, and the value of a piece of information can be further enhanced by linking together related pieces. However, composite data and cross-reference between data items raise a number of system issues that have not been addressed properly before. Lo defines a new multiservice storage architecture that meets the needs of existing and emerging applications and can support multiple file abstractions. He also explores a number of related design issues. Researchers in the areas of distributed systems, network multimedia and network storage services will enjoy this book.
