Hierarchical Delegation and Reservation of Lookup Keys
First Claim
1. A method of reserving lookup keys in a computer communication system including a hierarchy of key manager nodes, the method comprising:
- receiving a first reservation request at a first key manager node at a first level of the hierarchy of key manager nodes, the first reservation request requesting reservation of a lookup key;
determining whether or not the first key manager node has authority to grant the reservation request; and
in response to determining that the first key manager node does not have authority to grant the reservation request, sending a second reservation request requesting reservation of the lookup key to a second key manager node that is at a second level of the hierarchy of key manager nodes.

Abstract
A method of reserving lookup keys in a computer communication system including a hierarchy of key manager nodes includes receiving a first reservation request at a first key manager node at a first level of the hierarchy of key manager nodes. The first reservation request requests reservation of a lookup key. The methods include determining whether or not the first key manager node has authority to grant the reservation request, and, in response to determining that the first key manager node does not have authority to grant the reservation request, sending a second reservation request requesting reservation of the lookup key to a second key manager node that is at a second level of the hierarchy of key manager nodes.

11. A key manager node, comprising:
a processor configured to receive a first reservation request from an application, the first reservation request requesting reservation of a lookup key, configured to determine whether or not the key manager node has authority to grant the reservation request, and in response to determining that the key manager node does not have authority to grant the reservation request, configured to send a second reservation request requesting reservation of the lookup key to a second key manager node that is at a higher level of a hierarchy of key manager nodes than the key manager node. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A hierarchical key management system, comprising:
-
a plurality of key manager nodes arranged in a hierarchy including a root key manager node and a plurality of intermediate key manager nodes; wherein each of the intermediate nodes is configured to receive a first reservation request from an application or a lower level key manager node, the first reservation request requesting reservation of a lookup key, configured to determine whether or not the intermediate key manager node has authority to grant the reservation request, and in response to determining that the intermediate key manager node does not have authority to grant the reservation request, configured to send a second reservation request requesting reservation of the lookup key to a second key manager node that is at a higher level of the hierarchy than the intermediate key manager node.
