25G Ethernet consortium releases 25G/50G Ethernet specification, focuses on multivendor interoperability

January 31, 2017

The 25G Ethernet Consortium completed the first 25G and 50G Ethernet plugfest at the University of New Hampshire InterOperability Laboratory (UNH-IOL) in Durham, New Hampshire, reporting record participation from the vendor community.

During the plugfest, 16 companies attended the week-long event where they engaged in a wide variety of test scenarios including auto-negotiation and stressed conditions.

These companies focused on vendor interoperability including adapters, switches, test and measurement devices, and interconnects. Additional areas of focus centered on proving...

The Importance of Auto-Negotiation in Ethernet Architectures

October 28, 2016

The critical role of standards in today’s environment is often overlooked, because their inherent nature is to make sure you don’t notice it working. Imagine going on a job interview in a world without standards. If you were to ask someone for directions to your interview, they might tell you it’s 500 steps away, but they have a longer stride so you ended up having to walk 1000 steps and you were late. You take out your laptop to give...

The 25 Gigabit Ethernet Rollout: Expect the new Ethernet standard show up quickly in data centers and campus networks

October 18, 2016

IP traffic is predicted to grow 10 fold in less than 10 years. This fact alone speaks to why even incremental increases in Ethernet speeds are important. The ever-rising demand for data is driven by cloud services and already can be seen in early Internet of Things devices. This trend helped lead to development of the 25 Gigabit Ethernet data rates. Even though the technology is rather new, in the two years since the 25 Gigabit Ethernet Consortium was created,...

5 Challenges for 25G Ethernet

September 28, 2016

The UNH-IOL has been testing Ethernet products since its inception in 1988, and over the years we have come across some Ethernet products that really puzzled us. Here are the top problems we see.

Not supporting or disabling auto-negotiation: The importance of auto-negotiation (Aneg) to 100G interoperability was acknowledged by making it mandatory to be fully compliant to IEEE 802.3 Clauses 92 and 93. The more recent 25G standard also mandates Aneg.

Not supporting Aneg could...

UNH-IOL capitalizes on data center growth with 25G Ethernet testing service suite

September 14, 2016

The University of New Hampshire InterOperability Laboratory (UNH-IOL) has begun offering 25 Gbps Ethernet Testing at its facility in Durham, New Hampshire, targeting equipment vendors that are selling to data center providers and service providers that are using higher network speeds to support cloud-based services.

While 10G is still a dominant network speed, Ethernet technology is migrating to 25 Gbps per lane to take on current silicon and system design. What makes 25 Gbps compelling is that it is...

Industry events demonstrate Ethernet speeds

July 15, 2015

Ethernet's ability to evolve is a true testimony to its design. Starting at 10 Mbps in 1983, Ethernet now tops out at 100 Gbps with 400 Gbps in the works. During the week of June 22, 2015, the Ethernet community came together at the UNH-IOL in Durham NH for two events that kept Ethernet moving forward. I attended the events on June 23 and met with John D'Ambrosia, chair of the Ethernet Alliance and Jeff Lapak, Senior Manager, Ethernet Technologies...

Ethernet Standards Ramp Up For Faster IT

July 1, 2015

"Fast IT" has become a marketing slogan, and is also a very real challenge for today's IT professionals. But rolling out new applications on the fly, providing continuous improvement, and adapting to changes and feedback in real time can only happen if your basic IT infrastructure is extremely sound.

In pursuit of this robust architecture, the Ethernet Alliance held its largest plugfest to date at the University of New Hampshire InterOperability Laboratory (UNH-IOL), last week. Engineers from 23 companies...

Ethernet industry builds on innovation

February 25, 2015

This year is shaping up to be an active one for Ethernet as the industry builds on innovations that occurred in 2014. The University of New Hampshire InterOperability Laboratory (UNH-IOL), an independent provider of broad-based testing and standards conformance services for the networking industry, stands ready to support the industry with expanded interoperability testing and support for 40 and 100 Gigabit Ethernet (40G/100G), according to Jeff Lapak, senior manager, Ethernet Technologies, at UNH-IOL. The lab sees considerable interest in 40G...
