A method of passing data between objects located distributed among a plurality of virtual address space domains established by processes executing on a data processing system comprises several steps. First, a session initiation message from a source object in a domain is broadcast to other objects in the domain. Responsive to receipt of the session initiation message by a domain agent (a type of object) for the domain, forwarding the session initiation message from the domain agent to each of a plurality of domain agents in other virtual address space domains. Responsive to receipt of the session initiation message by the domain agent for a second domain, transmitting the session initiation message from the domain agent for the second domain to an agent object in the second domain for the source object. Finally, responsive to receipt of the session initiation message by the agent object for the source object, establishing a session between the agent object for the source object and a target object for passage of data. |
