40 Gigabit Ethernet: The migration begins
This article is part of the Network Evolution issue of Vol 3/ No.6
The need for more speed and capacity never goes away. Most enterprises are still rolling out 10 Gigabit Ethernet links in their networks, but already network architects and engineers are preparing for the future because data traffic never stops growing. Early adopters are testing and deploying the first generation of 40 Gigabit Ethernet (GbE) switches and routers to get a step ahead of this continuous onslaught of traffic. “We are seeing incidental peaks of traffic nearing 10 Gbps,” said Jeroen van Ingen, a network engineer at the University of Twente in the Dutch city of Enschede. “Given the traffic growth over the years, we expect to need more capacity within 12 to 24 months. That’s why we decided that new core equipment should support 40 GbE.” Van Ingen is not alone in predicting the need for 40 GbE and beyond. Research from the Dell’Oro Group forecasts the overall Layer 2 and Layer 3 Ethernet switch market will reach $25 billion in 2016, with 40 and 100 GbE technology approaching $3 billion in sales. Meanwhile, Infonetics ...

When it comes to 100 Gigabit Ethernet, network monitoring tools fall short. Analyst Jim Frey explains which tools are ready and which must change.
With 40 and 100 Gigabit Ethernet so new, what could possibly drive the need for 400 Gigabit Ethernet in the enterprise? Hint: It’s not just the WAN.
Columns in this issue
It may seem early to consider 40 and 100 GbE migration since 10 GbE is so young, but with the explosion of video and cloud applications, users must build 10 GbE networks today that can be easily migrated in the future.
