    ABSTRACT

    We describe the Tycoon approach to scale the successful notion of a uniform, type-safe persistent object store to communication-intensive applications and applications where long-term activities are allowed to span multiple autonomous network sites.

    Exploiting stream-based data, code and thread exchange primitives we present several distributed programming idioms in Tycoon.

    These programming patterns range from client-server communication based on polymorphic higher-order remote procedure calls to migrating autonomous agents that are bound dynamically to network resources present at individual network nodes.

    Following Tycoon's add-on approach, these idioms are not cast into built-in syntactic forms, but are expressed by characteristic programming patterns exploiting communication primitives encapsulated by library functions.

    Moreover, we present a novel form of binding support for ubiquitous resources which drastically reduces communication traffic for modular distributed applications.
