Sales have doubled since the third quarter a year ago.Cisco dominated the enterprise router market in the third quarter, accounting for 80% of sales.Layer 2 and Layer 3 Ethernet switch sales climbed 6% in the third quarter, to $3.95 billion. But 10 Gigabit Ethernet and Layer 4-7 gear were particularly hot: 10 Gigabit sales were up 29% from the previous quarter, and Layer 4-7 gear sales climbed 19% from the same quarter a year ago. With multi-layer switches, SSL technology is becoming a popular feature, Infonetics reports, as 51% of the $181 million in gear sold included SSL capabilities.The SSL uptick could be a sign that enterprises are installing more security measures in data centers, since Layer 4-7 gear is usually put in front of banks of Web and application servers. SSL is also used on Layer 4-7 switches to support SSL-based VPNs, which allow end users to access secure applications via a Web connection and do not require client-side software.As for carrier gear, the worldwide service-provider router and switch market hit $1.86 billion in the third quarter, an increase of 3% over the second quarter of 2005. While Cisco dominated most enterprise switch and router categories, its lead in carrier gear is smaller, with 41% of the market.
