Abstract

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.

a destination access node in a network declaring a locally supported communication protocol for participating in control of a message exchange using said locally supported communication protocol between access nodes, wherein said supported communication protocol is associated with an internode Functional Address, and wherein declaring said supported communication protocol comprises includes

marking an internode Functional Addresses associated said locally supported communication protocols;

receiving an undirected message from an origin access node to locate a target resource;

determining that access to said target resource is provided;

determining the communication protocol used by said target resource; and

6. The method according to claim 5, wherein broadcasting to access nodes supporting the same communication protocol, a control message comprising information related to the location of the target resource, further comprises broadcasting a control message comprising information related to said location of said target resource the internode Functional Address over a network spanning tree.

7. An access nodes buffering information regarding the location of more frequently requested resources, said access node comprising:

means within an access node in a network, for declaring a locally supported communication protocol for participating in control of a message exchange using said locally supported communication protocol between access nodes, wherein said locally supported communication protocol is associated with an internode Functional Address, and wherein declaring said locally supported communication protocol includes marking said internode Functional Address as being associated with said locally supported communication protocol;

means for receiving a control message from a destination access node providing access to a target resource, said control message comprising information related to a location of said target resource;

means for determining that a Local Directory Database does not include said information related to said location of said target resource; and

means for storing said information related to said location of the target resource in said Local Directory Database.

8. The access node of claim 7, wherein said means for receiving a control message from a destination access node providing access to a target resource further comprises means for receiving information that was broadcast, using said internode Functional Address, by said destination access node, to access nodes supporting the same communication protocol as the target resource.

9. The access node of claim 7, wherein said means within an access node in a network for declaring a locally supported communication protocol further comprises means within an origin access node in a network for declaring a locally supported communication protocol and wherein said system further comprises:

means for receiving a message to locate said target resource;
