You +would have a single system, for example, handling just combat resolution, +and you would have another system that would keep track of the database... +or on an even more molecular level (assuming you have a very large world +with huge database demands) a database service that is strictly dedicated to +handling certain types of objects (like dynamic world objects such as rocks +and such, as opposed to character objects like their posessions in their +backpacks for example). + +You would have other servers running the service managers for the AI of the +monsters, etc, etc, etc... + +So instead of dividing up the world into geographical sectors and having a +single system handle each sector... you would divide the world up into +different processes, and have each system handle the specific process for +the entire world. + +Let me know if I'm getting pretty close to what you're trying to say here. +;) My only question on the whole thing would be... what happens if you run +into a problem where activity on a process gets to be too much for a +server... would you be forced to upgrade that server? Or could you +theoretically split the process between two systems? (running the same +serice twice in the same cluster, on different systems). + +----- Original Message ----- +From: "Vincent Archer" <<A HREF="mailto:archer@nevrax.com">archer@nevrax.com</A>> +To: <<A HREF="mailto:nel@nevrax.org">nel@nevrax.org</A>> +Sent: Monday, February 19, 2001 10:33 AM +Subject: Re: [Nel] Dynamic load balancing? + + +><i> According to Glaze: +</I>><i> > Hello, +</I>><i> > +</I>><i> > I have one "small" question and I hope this is the right place to ask +</I>it.

In that classic model, each processus is a +</I>><i> complete copy of the code. It contains everything, from spell effects +</I>><i> to pathfinding to combat code. Each process serves a specific "area", +</I>><i> which is defined by an X/Y/Z box (or, for EQ, a zone ID number, since +</I>><i> each area is strictly separate). +</I>><i> +</I>><i> We're not going to use this approach.

That is, each service +</I>><i> provides specific functions. For example, all items in the game are +</I>><i> handled by a single service.
