The present invention relates to a method and system for pre-loading access nodes with the location of more frequently requested resources. The method includes declaring each locally supported communication protocol for participating to control message exchanges between nodes supporting a same communication protocol; receiving a message to locate a target resource; searching for information related to the location of the target resource in the Local Directory Database; broadcasting an undirected message to the other access nodes in the network to locate the target resource; receiving a control message from the destination access node providing access to the target resource, this control message comprising information related to the location of the target resource; and storing the information related to the location of the target resource in the Local Directory Database.
