This presentation provides a high level overview and introduction to TRILL, and related technologies.

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.

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 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 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.

Representing the first public summary of objective, multi-vendor Ethernet conformance and interoperability testing conducted over an extended period. This whitepaper summarizes seven years of Fast and Gigabit Ethernet testing data gathered through the end of 2005, including test reports from 900 individual products representing several hundred companies.

Learn about the latest information pertaining to USGv6 Revision 1 (USGv6-r1) and IPv6 Ready Logo. Testing is available now for USGv6-r1. Starting in November 2022 buyers will no longer be able to accept SDoCs for the previous revision of the profile. The UNH-IOL's accredited testing can test your products for USGv6-r1 and IPv6 Ready Logo.

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.

SuperDemo 2003 was the worlds most advanced and comprehensive live test of multiple MPLS services operating concurrently across a multi-vendor MPLS network. The MPLS/FR Alliance SuperDemo included 14 different companies showcasing MPLS services and features such as VPLS, ATM/FR/Ethernet over MPLS, BGP MPLS VPNs and Fast re-route.

SuperDemo 2004 was the product of a partnering of the Multiservice Switching Forum (MSF) with the MPLS & FR alliance. Eleven companies participated in expanded testing including advanced service provider applications. The collaboration of the MSF and the MFA took the meaning of success to another level in the industry. The Multi-Vendor MPLS infrastructure was constructed for stability and reliability. The Demonstration of VoIP services across this network clearly conveyed a feeling of resilience.
