Understanding Traffic Characteristics in a Server to Server Data Center Network

Understanding and Abstracting Total Data Center Power

The alarming growth of data center power consumption has led to a surge in research activity on data center energy efficiency. Though myriad, most existing energy-efficiency efforts focus narrowly on a single data center subsystem. Sophisticated power management increases dynamic power ranges and can lead to complex interactions among IT, power, and cooling systems. However, reasoning about tot...

Coarse-grained traffic matrix estimation for data center networks

We address the problem of estimating the real-time traffic flows in data center networks (DCNs), using the light-weight SNMP data. Unlike the problem of estimating the traffic matrix (TM) across origin-destination (OD) pairs in ISP networks, the traffic flows across servers or Top of Rack (ToR) switch pairs in DCNs are notoriously more irregular and volatile. Although numerous methods have been...

Traffic Isolation on Multi-Tenant Data Center Networks

To satisfy demanding clients and o↵er features comparable to the competition, infrastructure-as-a-service providers (IaaS) need fast, flexible and easily configurable local networks. OpenStack is one of the most well known open IaaS platforms. Although OpenStack meets most needs of a IaaS platform, its virtualized network implementation still lacks flexibility to support isolation on a multi-te...

Understanding the limitations of retrospective analyses of poison center data.

Limitations of retrospective analyses R.S. Hoffman Poison centers provide poison prevention and safety information, professional education, and assistance with the diagnosis and treatment of poisoning. These invaluable efforts are linked to medically and legally mandated record keeping, which entails continuous and archived collection of data over time. Surrounded by gigabytes of information re...
