    Since publication of the IEEE computer society MSS (mass storage system) reference model, two implementation strategies have been competing in the development of the model. Both strategies stress location transparency of files. However, in one strategy the location transparency is confined within a node on the network, requiring cooperation between differing types of nodes. The other strategy stre... View full abstract»
