Abstract
Systems and methods that supply a global knowledge on what nodes are available in the system, via employing routing tokens that are analyzed by a centralized management component to infer status for the nodes. When nodes fail, the routing tokens associated therewith are acquired by neighboring nodes, and the global knowledge updated. Moreover, upon inferring a failed or down status for a node, a challenge can be sent to a node reporting such failure to verify actual failure(s).
