Recent work has shown the utility of spatial detection of anomalies via crosslink traffic comparisons. In this paper we identify three advances that are needed to make such methods more useful and practical for network operators. First, anomaly detection methods should avoid global communication and centralized decision making. Second, nonparametric anomaly detection methods are needed to augment current ...
