1. A method comprising: receiving, using a processing device, an update message from an input source, the update message identifying a live object and containing data for updating a property of the live object; identifying a category of the update message based on the input source; determining a node having a node type to which the update message is to be routed based on a mapping of categories of update messages to node types, the mapping controlling an amount of update message traffic through nodes of a routing network; routing, using the processing device, the update message to the node having the determined node type; causing the node, through the update message, to determine a client, different from the input source, that has registered for updates of the live object; causing the node to route the update message from the node to the client; and causing the client to process the update message and to update the property of the lire object.
