It’s not too early to worry about 40 and 100 GbE migration

A few years ago, a group of network engineers unanimously laughed in my face when I brought up an article I was writing about 10 GbE migration. All of them were still using 1 GbE, and only a few were even testing 10 GbE switches. The transition, they said, would be long and slow. It was the classic gap between a user’s reality and a journalist’s research. So it may seem even stranger this month that we have produced an entire issue about 40 and 100 GbE migration (we even have a piece pondering the future of 400 and Terabit GbE). After all, we are only at the very beginning of widespread 10 GbE implementation. But things are different now than they were a few years ago. The need for capacity and speed is exploding as network teams build private and hybrid clouds and deliver video throughout their campuses and branch offices. So even if they don’t need 40 GbE today, they’ll need to build networks that can be transitioned in the future. And that won’t be easy, as news director Shamus McGillicuddy reports in his feature “40 Gigabit ...
