Summary form only given. Many key tasks in computer network monitoring, such as load balancing and the detection of anomalies (e.g., DoS attacks, link failures, and routing loops), fundamentally require a whole-network perspective - that is, methods of 'spatial' traffic analysis. A key challenge to advances in this area is posed by the fact that the 'space' in question, deriving from a network, is not some Euclidean sub-space but rather a graph. We focus on the problem of developing analyses sensitive to 'spatial' scale and introduce a framework for graph-based wavelets. In conjunction, we also consider the important issue of characterizing the underlying 'spatial' auto-correlation structure.
