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...
