摘要:
A system and method are described for generating a unique name for a particular subordinate resource of a computer system having a plurality of subordinate resources associated with superior resources. A superior resource is identified that is associated with the particular subordinate resource, and the name of that superior resource is ascertained. A portion of the superior resource name is selected and combined with a unique counter value from a global counter, where the global counter provides a different counter value to each subordinate resource of the plurality of subordinate resources. In this manner, the generated subordinate resource name for the particular subordinate resource is unique across all subordinate resources of all superior resources, not only across subordinate resources of one of the superior resources.

In one embodiment, a method for using a two-hop relay includes receiving an update message for a distance vector routing protocol from a first neighbor. The update message is sent to a different neighbor. Often, it is first determined whether the receiving node is a relay node for the first neighbor in the protocol. The relay node is a node preferred to update a particular node two hops from the first neighbor. In another embodiment, a method for serving as the two-hop relay includes receiving from each neighbor a first message that includes neighbor data that indicates nodes that are in direct communication with the neighbor. A relay set of fewer than all neighbors is determined. Every node two hops from the first node is updated using only the relay set of neighbors. The relay set is sent in a second message for the protocol.

Group key management in a mobile ad-hoc network (MANET) may be provided. Each network node associated with the MANET may comprise a group distribution key and a list of authorized member nodes from which a group key manager may be elected. The group key manager may periodically issue a new group key to be used in protecting communications among the network nodes. A compromised node may be excluded from receiving updated group keys and thus isolated from the MANET.

摘要:
A method for generating a unique subordinate resource name is disclosed where the method includes the steps of identifying a subordinate resource and the name of a related superior resource, truncating the superior resource name to form a truncated name, obtaining a counter number from a global counter, and appending the counter number to the truncated name to form an appended name which is assigned to the subordinate resource.
