Title: NEIGHBOR MONITORING IN A HYPERSCALED ENVIRONMENT
Abstract:
A network of N nodes performs a monitoring method, where the method is performed by each node. The N nodes are partitioned into domains according to a sorted order. The domains include a local domain in which the node is located and one or more remote domains. Each remote domain has a domain head designated to monitor member nodes in the remote domain. The node sends probes at a given frequency to actively monitored nodes that include all other member nodes in the local domain and domain heads in the remote domains. The node then determines whether each of the actively monitored nodes is up based on replies received from the actively monitored nodes in response to the probes.
