Lattice Based Traffic Measurement

摘要

A lattice of interconnected concepts is constructed from flow entries. Each concept describes a subset of flows and a subset of the flow attributes. Based on user queries, the lattice is used to build disjoint sets of flows referred to as flowsets. Each user query specifies one or more of the flow attributes to be measured. Each flowset includes one or more of the flows to thereby enable sharing of the hardware counters among the flows. One hardware counter is then assigned to each flowset.
