Recently, there has been a tremendous growth in the number of installed distributed computing platforms such as those for content distribution networks, cloud computing infrastructures, and distributed data centers. Such distributed platforms need a scalable end-to-end (e2e) network monitoring component to provide Quality of Service (QoS) guarantees to the services and improve the overall performance. An important challenge for a network monitoring infrastructure is the periodicity of the measurements as this aspect trades off the monitoring overheads with staleness of the results. In the Network Genome project, the authors explore the relationships between different e2e network metrics with the aim of leveraging such relationships for reducing monitoring costs while maintaining measurement accuracy.
