I implemented a mechanism for building a James Albus style hierarchical control network as suggested to me by Ben a few years ago. Because message passing between nodes had a maximum speed of about 18,000 messages per second, I also implemented an alternative form of message passing within a single Java virtual machine, in which the sending thread actually performs the message handing process in the receiving node via an ordinary method call. According to the Albus model, each level lower in the control hierarchy processes commands and perceptions at ten times the speed of the superior level. Another issue was suspended threads after sending a message to another node. I avoided many of these at the higher control levels, where events can last for a day or more, by a psuedo-conversational mechanism in which the message contains a UUID (universally unique identifier) that the recipient includes in the reply message, and which allows the restoration of task state in a new thread. By the way I also use a thread pool. I like the message passing, service oriented architecture (SOA) approach within the Albus model. My experiments to date have been within one JVM but I plan to use Jabber as the scalable transport between JVMs on a distributed network. Thanks to everyone for their input. The GPL seems to have the most support so that's what I'll plan for. Cheers. -Steve __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
