We are inundated with data. Resources to analyze the data are finite and expensive. Approximate answers allow us to explore much larger amounts of data than otherwise possible given available resources. Reducing the cost, if doable for a large fraction of the complex queries that run on this data, is of strategic importance because the savings can be re-invested into more sophisticated algorithms or be used as a key differentiator for analytics-as-a-service offerings. Unfortunately, state-of-art…

Seawall provides new ways to share the network in datacenters. SideCar While investigating how we could get explicit feedback from the network middle to the ends for Seawall, we struck upon a way to provide programmability on a modest fraction of all packets flowing through the switches.  Packets are re-directing, via sampling or marking, to commodity servers that are directly attached to and function as dedicated programmable processors for these packets. We call this the SideCar architecture. Using SideCar,…

NetMedic helps operators perform detailed diagnosis in computer networks. It diagnoses not only generic faults (e.g., performance-related) but also application specfic faults (e.g., error codes). It identifies culprits at a fine granularity such as a process or firewall configuration. Our work focuses on both the algorithmic aspects of detailed diagnosis as well as the important task of explaining diagnostic reasoning to the operator.

Overview Networks are being deployed extensively in large corporations, small offices, and homes. However, a significant number of "pain points" remain for end-users and network administrators. To resolve complaints quickly and efficiently, network administrators need tools that can assist them in detecting, isolating, diagnosing, and correcting faults. Furthermore, such tools should also detect network security breaches, possibly caused by innocent employees. The NetHealth project is about detecting, inferring, diagnosing, and recovering from user perceived performance…
