Top Ethernet switch vendors in Q2 2015
Ethernet switching revenue rose 9 percent sequentially to $5.6 billion in the second quarter of 2015, according to the IHS Infonetics Ethernet Switches report from IHS.
North America was the key growth driver with 14 percent sequential growth. China also contributed to the growth in Ethernet switch growth.
The IHS report said there was strong uptake of 40GE solutions in data center environments. At the expense of 10GE, 40GE port shipments rose 132 percent in Q2 2015 from the year-ago quarter.
Matthias Machowinski, research director for enterprise networks and video at IHS, said: “We did see muted demand for white box switch solutions, as web-scale data center operators await the release of 25/100GE solutions later this year, and once these become available, we expect the white box segment to become a key growth driver again in the global Ethernet switch market.”
