ABSTRACT:
A method for monitoring the availability of resources in a network comprises the computer-implemented steps of receiving an activity announcement packet from a node in the network; determining that the node is potentially inactive if no successive activity announcement packet is received from the node within a specified first time period; and determining that the node is inactive if no successive activity announcement packet is received from the node within a specified second time period.
