FlowRoute: Inferring Forwarding Table Updates Using Passive Flow-level Measurements ABSTRACT
"... in network topology can impact application performance. While improvements in protocol specification and implementation have significantly reduced reconvergence times, increasingly performance-sensitive applications continue to raise the bar for these protocols. As such, monitoring the performance o ..."

of routing protocols remains a critical activity for network operators. We design FlowRoute, a tool based on passive data plane measurements that we use in conjunction with control plane monitors for offline debugging and analysis of forwarding table dynamics. We discuss practical constraints that affect
Dumb money: Mutual fund flows and the cross section of stock returns,
- Journal of Financial Economics,
, 2008
"... We thank Nicholas Barberis and Judith Chevalier for helpful comments. We thank Breno Schmidt for research assistance. ABSTRACT We use mutual fund flows as a measure for individual investor sentiment for different stocks, and find that high sentiment predicts low future returns. Fund flows are dumb ..."

What FLOW does not measure is the amount of stock that is purchased with inflows; one cannot infer from this example that the technology fund necessarily used its inflows to buy Cisco. To the contrary, our assumption in constructing

Efficient conflict detection in flow-based virtualized networks
- In ICNC
, 2012
"... Abstract—In the current Internet, traffic is routed at the level of destination prefixes. The next-generation Internet requires control of traffic at the level of flows or flow aggregates. To accommodate fine-grained control, modern switching substrates (e.g., OpenFlow) maintain forwarding informati ..."

When using network virtualization, a technique that allows sharing of networking resources among different logical networks, the physical switch
J2EE Performance and Scalability- From Measuring to Predicting
"... Abstract — J2EE applications are becoming increasingly ubiquitous and with their increasing adoption, performance and scalability issues are gaining in importance. For a J2EE application to perform well and be scalable, both the platform on which it is built and the application design must be effici ..."

Industry-standard benchmarks such as the SPECjAppServer set of benchmarks help to evaluate the performance and scalability of alternative platforms for J2EE applications, however, they cannot be used to evaluate the performance and scalability of concrete applications built
Magnet: Robust and Efficient Collection through Control and Data Plane Integration
"... Despite being a core networking primitive, collection protocols today often suffer from poor reliability (e.g., 70%) in practice, and heavily used protocols have never been evaluated in terms of communication efficiency. Using detailed experimental studies, we describe three challenges that cause ex ..."
