Testing & Interoperability: How the UNH-IOL Continues to Impact NBASE-T Success Mike Klempa

Join us for this 20-minute webinar discussing:

  • Mission and focus of the UNH-IOL in the technology industry
  • The UNH-IOL contributions to the NBASE-T Alliance in leading multi-vendor interoperability events, and demonstrating NBASE-T capabilities and benefits such as 6-around-1 cable testing and Downshift
  • The importance of electrical conformance testing offered for NBASE-T products 
  • Strategies to develop the next generation of networking engineers

Testing Home Routers for World IPv6 Launch Timothy Winters

The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its fourth IPv6 Customer Edge (CE) Router Interoperability Test Event the week of April 16 - April 20, 2012 at its 32,000+ square-foot facility in Durham, New Hampshire. The test event brought together both users and suppliers of CE routers, also known as home router equipment. The purpose of the test event was to gain a perspective on the current status of IPv6 interoperability against the Internet Engineering Task Force (IETF) Basic Requirements for IPv6 Customer Edge Routers and support the Internet Society (ISOC) World IPv6 Launch. The eight participating vendor companies tested a total of ten distinct home router implementations throughout the week using publicly routable IPv6 addresses. Participants included Broadcom, CHT-TL IPv6 Testing Lab, D-Link, NDM Systems, Motorola Mobility LLC, Netgear, Time Warner and ZyXEL.

Observations discussed in this paper include:
* DHCP Solicits Frequency
* Renumbering
* No Default Route
* Forwarding before Address Acquisition
* DHCPv6 IA_PD & IA_NA Interactions

Testing TRILL (TRansparent Interconnect for Lots of Links) Christina Dube

The University of New Hampshire InterOperability Laboratory (UNH-IOL) hosted its second TRansparent Interconnect of Lots of Links (TRILL) Interoperability Test Event the week of November 26 – December 1, 2012 at its 32,000+ square-foot facility in Durham, New Hampshire. The test event brought together implementers of TRILL as well as test equipment manufacturers that support TRILL. The purpose of the test event was to gain a perspective on the current status of TRILL implementation and interoperability. Participants included Hewlett-Packard Networking, Extreme Networks, Ixia and Spirent Communications.

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.

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.
