Question about Load Balance

I was looking for some detail about Load Balance in Ice, but didn't find too much in the manual. The manual mentions Federated Service and Replicated Service, but doesn't expose enough details.

And it seems IcePack doesn't allow multiple servers register same Object Adapter(or Object) with different endpoints, I mean DNS can bind multiple IP with one domain name and can dispatch load to them.

Can you guys give me some guide to implement Load Balance through Ice?

Thanks,
Rong.

Sorry, I did a bit search in the forum after this post. Now I know two ways to load balance.

the simple way, use IcePack::Query::findObjectByType to get a randomly selected object.

the powerful way, use IceGrid.

If anyone knows any other approach, please tell me

Thanks,
Rong.
