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 UNH-IOL offers testing for the Broadband Forum Gfast Testing Certification Program which now includes 212 MHz certification. Testing for device types, including, DPU Devices, CPE, and Gfast chipsets. Learn more about our group test events, Plugfests, the current and future state of Gfast Certification our latest video.

Take a video tour of our wireless testing here at the lab with our state of the art octoScope Test Bed. Our wireless testing focuses on performance and quality of experience for the 802.11 WiFi technologies. Our octoScope testbed includes two 26” octoboxes, and one 38” octoBox with controllable turntable. It can also be configured for video over Wi-Fi testing, mesh testing (self-forming, self-healing functions of a mesh), high speed roaming and other wireless tests.

The forthcoming Broadband Forum G.fast Certification Program, based on the ID-337 test plan, presents a number of unique challenges, including requirements for testing multiple CPEs (customer premise equipment) connected to a DPU (demarcation point unit) using a multi-pair cable. This white paper describes an approach to the construction of a copper cable plant...

The IEEE 802.11 family of wireless LAN protocols defines multiple physical layers implementations of which direct sequence spread spectrum (DSSS, 802.11b) and orthogonal frequency division multiplexing (OFDM, 802.11a/g) are currently the most popular. Market pressures are forcing the convergence of multiple wireless protocols into the same access device, and shortened product design cycles dictate rapid prototyping of new or enhanced protocols. The computationally intensive signal processing algorithms and high data rates associated with these protocols necessitate dedicated hardware implementation of some portions of the signal processing chain, yet allocating separate hardware resources for each of the standards would make the "universal access device" bulky and inefficient. Re-using the same software-reconfigurable hardware to handle different processing algorithms would enable an efficient, flexible alternative to current prototyping and implementation methods. In this thesis, the feasibility of using Software Defined Radio architectures as a prototyping tool for wireless LAN baseband signal processor implementations is explored. Signal processing architectures and algorithms for DSSS and OFDM protocols were developed in the Simulink and Matlab environments, and were then translated to VHDL hardware descriptions. A reference design for a OFDM transmitter was synthesized for implementation on a Xilinx Virtex II FPGA, and functional and timing simulations verified the design correctness.

Fibre Channel is a computer communications protocol designed to meet the many requirements related to the ever increasing demand for high performance information transfer.

A technical overview of Fibre Channel

Fibre Channel, which is used for high-speed data transfers, supports several higher layer protocols including Small Computer System Interface (SCSI) and Internet Protocol (IP). Until now, SCSI has been the only widely used protocol over Fibre Channel. IP over Fibre Channel had not been successful mainly due to inadequate specification in the standards. Currently IP specifications have reached a stage where interoperable implementations are possible. Although some support does exist for SCSI on Linux, there is no support for IP on Linux. This thesis aims at designing, developing, testing and evaluating a Fibre Channel driver for IP on Linux.

• Why IPv6 interoperability testing is important
• What gets tested and why?
• How IPv6-only deployments are impacting interoperability testing
• How has IPv6 testing impacted overall deployment of IPv6
• Why USGv6 has been critical to IPv6 adoption
• Why IPv6-only is likely to happen sooner than expected
• What should IPv6/IPv4 feature parity look like

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

Please join UNH-IOL’s Senior Engineer, Lincoln Lavoie, on this webinar as he discusses expanded WiFi testing capabilities based on the Broadband Forum’s WT-398 test plan, a set of industry-agreed upon performance testing metrics for WiFi systems that enable service providers to differentiate service offerings and assure wireless quality of service for customers. 

Join the UNH-IOL as we walk thru which tests are mandatory for Plugfest #9 based on testing from our previous Plugfest (#8). We will review for both NVMe drives and NVMe-oF targets. In addition, we will walk thru the new tests that have been added for NVMe v1.3 features.
