`
`(57) ABSTRACT
`
`A network routes update messages containing updates to
`properties of live objects from input sources to clients
`having the objects. When the clients receive live objects, the
`clients identify the object IDs associated with the objects
`and register the object IDs with the routing network. The
`routing network is adapted to selectively send update mes-
`sages to nodes in the network and the nodes forward the
`messages to the clients. One implementation uses a hierar-
`chy of registries to indicate which nodes and clients receive
`which update messages. Another implementation assigns
`update messages to one or more of N categories and nodes
`to one or more of M types, and the gateways maintain
`mapping between categories and types. To ensure that
`clients receive all of the update messages for which they
`register, the clients connect to client proxies that in turn
`connect to at least one node of each type.
