A system and method related to efficiently searching for an object in a
network including a plurality of realms, e.g., a plurality of local area
networks (LANs). The method may ensure that nodes within a LAN are able
to locate objects within that LAN using only computing resources on the
local LAN. Thus, expensive WAN transfers may be avoided where possible.
The system may also scale to many nodes. Nodes may not be required to
know about every other node in the system. Mechanisms for re-distributing
object location information among nodes as nodes are added to and removed
from the system are also described.
