Networking giant Cisco is losing market share in its core router market to rival Juniper Networks.

Figures from Infonetics Research show Cisco market share slipping from 72 per cent in the third quarter of 2003 to 58 per cent in the third quarter of 2004. Over the same period Juniper grew its market share from 20 per cent to 36 per cent. But the market as a whole is still growing. Infonetics estimates worldwide revenue for service provider routers and switches at $1.6bn, up 28 per cent on the same period last year.

Merrill Lynch analysts spotted a similar trend. They estimate Juniper increased market share from 12.9 per cent to 14.8 per cent sequentially. Most of these gains were made at the expense of Cisco. Analysts warned that Cisco's router revenues were showing more volatility than the market as a whole. More details here.
