Transparent Interconnection of Lots of Links (TRILL) Deployment Nears UNH-IOL

An exciting milestone on the road to TRILL deployment occurred from August 3rd to 5th 2010 at the University of New Hampshire InterOperability Laboratory (UNH-IOL), as a group of companies attended the first multi-vendor TRILL plugfest. The plugfest was successful in demonstrating interoperability between TRILL devices. It was a first step towards wide deployment of TRILL and valuable knowledge for increasing TRILL interoperability was gained through the event.

Timing Challenges in the Smart Grid Jason Allnutt, Dhananjay Anand, Douglas Arnold, Allen Goldstein, Ya-Shian Li-Boboud, Aaron Martin, Cuong Nguyen, Bob Noseworthy, Ravi Subramaniam, Marc Weiss

Correct time and timing is one of the foundational elements in enabling the communication and orchestration of technologies for accurate and optimal wide area monitoring, protection and control (WAMPAC) in the power industry. The National Institute of Standards and Technology (NIST) and the International Electrical and Electronic Engineer-Standard Association (IEEE-SA) conducted a workshop to gather inputs from stakeholders to identify, analyze, and provide guidance on technologies, standards and methodologies for addressing the practical timing challenges that are currently being experienced in wide area time synchronization.

The OCP NIC 3.0 Fixture & What is Means for Datacenters

The Open Compute Project (OCP) in conjunction with the UNH-IOL, has projects underway to integrate and validate new form factors for using PCIe in servers to address server needs. Let’s now review the limitations typically faced by server manufacturers, such as thermal considerations, connector size, and data rates, and solutions to these limitations in this interview with David Woolf and Mike Klempa at the lab.

The Extended Sockets Interface for Accessing RDMA Hardware Dr. Robert Russell

The Extended Sockets API (ES-API) is a specification published by the OpenGroup that defines extensions to the
traditional socket API which include two major new features: asynchronous I/O, and memory registration. These
features enable programmers to take advantage of today's
multi-core processors and Remote Direct Memory Access
(RDMA) network hardware, such as iWARP and InfiniBand interfaces, in a convenient yet efficient manner.
This paper describes the UNH EXS interface, an implementation of the ES-API that provides additional API
facilities which enable a programmer to utilize RDMA network hardware while selectively choosing those features of
this interface that are most germane to the particular application. In addition, the UNH EXS interface is implemented
entirely in user space on the Linux operating system. This
provides easy porting, modification and adoption of UNH EXS, since it requires no changes to existing Linux kernels.
Preliminary results demonstrate that applications based on
EXS can achieve high bandwidth utilization and low CPU
overhead.
