Hi Olish. Thanks for the comments. Yes, one way to distribute load would be to take an implementation of our existing Asset service (which is REST based) and host it elsewhere. As for Squid, I suspect that’s something one would use internally or as a local cache for a group of regions rather than as a way to distribute data. Asset security in an “open” grid is also an issue. However, having a “closed” grid doesn’t alter the situation all that much, as the asset data still has to go to a person’s client.

Thanks for the pointer Christian. I am aware of the AWG though I simply haven’t had time to follow it recently. I know other developers from OpenSim have been involved with it, though I think it’s always hard when the only time you have to spend on a project is your spare time!

Did you had a look at what the Architecture Working Group in Second Life is doing? It was initiated by LInden Lab but is a community effort which aims to define a protocol for decentralized servers.

The hope is that OpenSim is part of that in the end.

Trust is of course a big issue here and widely discussed and there are some ideas around a web of trust floating around.

Linden Lab seems also committed to port their existing grid step by step towards this.

I myself want to start soon on implementing an agent domain, if I would then be able to connect via this to an opensim region, that would be cool

There’s also a problem with data security for grids wanting to protect residents creation from thief. Distributed asset servers may not be maintained by external people in this case.

Anyway, I like this idea of a distributed system.

Using web servers to store assets/textures is a very interresting way to decrease load on the central database. May be 2 or more webservers could host these as mirrors, this way, if one comes offline, the central grid asset server knows another online location ?

I saw recently the Open UGAI hosted on web servers. May be could it be used to implement such a distributed system ?

Or may be using Squid on each server hosting regions configured to look up assets and textures at other Squid parent caches ?
