  • Decentralized tuple space is an e®ective
    paradigm for distributed collaborative applications since
    its loose decoupling, availability and °exibility in system's
    organization. However, there are very few research results
    on its replication and consistency. This paper presents
    a decentralized tuple space model to enable tuple update
    by creating loose update links among decentralized Tuple
    space nodes. Besides, tuples are grouped with tuple types,
    the unit of being applied a replication policy, which con-
    trols the distribution of replicas. The model is simulated
    by Desmo-J. The experiments show that applying di®er-
    entiate replication policies used for di®erent purposes is
    absolutely necessary, because no single policy is suitable
    under all use patterns.
