Abstract:

In message-oriented distributed object system, cooperating objects exchange messages and various functions are carried out as a side effect of message exchanges. As objects range from an icon on the screen to a full featured server, the set of messages they can understand is also different. An object may not know the properties of all the objects it is communicating with. Objects may acquire new functionality at runtime and this makes the problem even more difficult. This paper presents message handling in the Bond distributed object system. Bond uses KQML as a communication language allowing every object to parse every message. The solution for the semantic understanding of messages are the subprotocols - highly specialized, closed set of commands. Being object instances themselves, subprotocols can be generated dynamically or stored into persistent storage. Objects implement the handling of subprotocols in their class definitions. Objects can be extended at runtime with probes to understand new subprotocols or, in some cases, can dynamically generate or learn new subprotocols.
