The NetWiser project spans several areas of data center networks, from designing new scalable network architectures, understanding network failures
and developing techniques for improving availability of services
hosted in the cloud.
- Understand network failures in data centers:
The aim is to characterize failures of network devices
in data centers by analyzing
failure incidents and correlating them with network traffic, estimating impact of failures, and deriving implications for designing future network architectures. [SIGCOMM 2011].
- Design scalable and flexible data center network architectures
VL2 is a new data center network architecture designed for hundreds of thousands of servers and built from commodity switches that enables high-bisection bandwidth between all communicating server pairs, agility in mapping any service to any server, and achieves graceful performance degradation under failures [SIGCOMM 2009, CACM 2011].
