Abstract
A technique is performed in a first device of a set of devices. The technique involves receiving a query message from a network node, the query message requesting data regarding a network resource. The technique further involves accessing an identifier which indicates whether the first device is in charge of the network resource, and providing a response message to the network node in response to the query message. The response message is provided after waiting a predefined amount of time when the identifier indicates that the first device is not in charge of the network resource and there is reason to believe another device of the set is operating. The response message is provided without waiting the predefined amount of time when the identifier indicates that the first device is in charge of the network resource. Moreover in some situations, the first device may choose to not respond.
