Revenues deriving from sales of Ethernet switches rose by almost a third in the year leading to the end of the second quarter of 2010.
Figures from analyst IDC show a 32.7 per cent annual increase in revenues for Ethernet switches.
Meanwhile, the Ethernet routing market also saw growth at the more modest rate of 11 per cent year-on-year.
Data centre and cloud computing installations helped to drive investments into high-speed equipment, particularly 10 Gbps devices.
Over the second quarter, more than a million ports supporting this level of bandwidth were shipped.
Rohit Mehra, director of enterprise communications infrastructure at IDC, says: "The second calendar quarter builds on the performance of the first, which is what the market delivered, showing strong year-over-year growth from the slowdown the market witnessed in 2009."
IDC's enterprise communications infrastructure continuous intelligence service addresses topics such as small office, home office, headquarters and branch infrastructure to provide insight into trends in the networking market.
