Abstract
Unique identifiers referred to as “keys” are generated for objects stored on each node. When a container object including at least one embedded object is transferred from a sending node to a receiving node, the sending node sends the key uniquely identifying the embedded object to the receiving node to determine whether the embedded object is already stored on the receiving node. If the receiving node indicates that the embedded object is already stored at the receiving node, then the sending node determines that the embedded object does not need to be sent to the receiving node. In that case, if the embedded object has not been sent, the sending node does not send the embedded object. If the sending node has already started sending the embedded object, then the sending node terminates sending of the embedded object.
