- Summary:
- Network statistics collection, calculation, and reporting, referred to as network telemetry, faces the problem of competing performance and flexibility demands. This dissertation introduces a novel approach to balancing these requirements. Tensions between design goals are overcome by exploiting hardware heterogeneity, where hardware elements fill specialized roles and careful software structuring maps activities to appropriate hardware.The axes of performance addressed here are coverage, throughput, and cost. Coverage can be gauged by the number of simultaneous data flows that a telemetry system can measure accurately. Coverage is important for application correctness, but it is often sacrificed in favor of higher throughput or lower cost because high coverage requires large memories that are inherently slow and expensive. I show that combining processors with heterogeneous memories can yield a somewhat surprising result, namely that high coverage and throughput can be achieved at low cost.Flexibility describes a telemetry system's capability to support diverse application needs, including concurrent measurement and late binding of potentially complex metrics. A small reduction in performance greatly increases flexibility. By enhancing system components to summarize data in an efficient universal format, a hybrid telemetry system can lift metric calculation to software for flexibility by design, while still exploiting workload properties and hardware heterogeneity for high performance.Validation and characterization of underlying principles is the third contribution. The major system elements have been validated with terabit rate implementations and simple but accurate performance models generalize results and guide future work.
