[Opensim-dev] load sharing.....

[バンション ヨハン]

Hi Terry,

As Adam suggested, the 3Di load balancing code has much of the functionality you request. We can already clone a region and specify for each copy how much it should update. We haven't implemented the scenario you describe (an active region with a standby region that you could switch do), but it is just a matter of extending the GUI and making small extensions to the current code. 

So it is no technical problem, but is it worth doing? Who do you think would be interested in this functionality? I could do this, or direct someone to do it, if it is useful, but if it ends up not being used I'd rather use my time on other things.

/Johan

I know the 3Di load balancing code could potentially lend itself to this sort of application.

The best method would be to somehow serialise the scene regularly and send that to a home sim, then write an application plugin to catch exceptions and if one occurs, manually send a "force teleport" (also known as a border crossing packet) to jump the user onto the standby.

I don't actually think that would be insanely difficult to do.
