a programmable work station used to work in a network comprises a conventional operating system and a network layer control program. in addition, the work station includes a support subsystem, application of collaboration that liaises with the application programs.the subsystem responds to a predetermined application program calls, in order to create a logical network model of a collaborative environment. the model includes sets of shared application program sharing data and resources across nodes and links of the logic channels, the specialized data sharing.the subsystem cooperates with the network layer in order to establish the necessary physical links in the implementation of the model in a physical network, and transparently from the application program.
