Cisco Systems continues to lose market share to Juniper Networks in Internet core routing, according to the latest figures from Dell'Oro Group.
According to Dell'Oro's data for the third quarter, Cisco's share of the $US680.6 million market for Internet core routers was 69 per cent, down from 75.4 per cent in the second quarter, and 80.2 per cent in the first quarter. Worldwide revenue in those quarters was $503 million and $372.9 million, respectively.
Juniper's share grew from 22.4 per cent in the second quarter to 30 per cent in the third quarter. The company's market share in the first quarter was 17.3 per cent.
The market overall grew 35 per cent in the third quarter, on top of an equal 35 per cent growth rate in the second quarter. Juniper's third-quarter revenue growth was more than double the market, at 78 per cent. Cisco grew less than the overall market, at 23 per cent.
Avici Systems, the distant No. 3 player in Internet core routing, almost doubled its revenue in the third quarter but still has less than 1 per cent market share, Dell'Oro says.
