HeteroSketch - Coordinating Network-wide Monitoring in Heterogeneous and Dynamic Networks

Explore a conference talk on HeteroSketch, a framework for coordinating network-wide monitoring in heterogeneous and dynamic networks. Delve into the challenges of modern network monitoring and learn how HeteroSketch addresses issues of hardware heterogeneity and dynamic resource allocation. Discover the framework's two main components: a profiling tool for quantifying hardware capabilities and an optimization framework for efficient task placement and resource allocation. Understand how HeteroSketch enables optimized deployments for large networks and responds to network topology, traffic, query, and resource dynamics. Examine the evaluation results showing significant resource overhead reductions compared to prior approaches while maintaining monitoring performance, coverage, and accuracy.
