Sales rose 11% sequentially and 22% year-on-year in the fourth quarter to $112.9m (£70.49m). For the full year to the end of December, sales were up 18% on 2008 to $394.1m.

He added that Riverbed's cornerstone WAN optimisation technology was now "firmly established" as a priority spend in enterprise IT budgets.
