* Q2 rev up 11 pct to $24 mln (Adds R&D spend in para 1, background in para 6, share closing in para 7)
July 7 (Reuters) - Canadian network equipment maker Sandvine Corp posted a steep decline in quarterly profit, hurt partly by a surge in research and development expenditure.
For the May quarter, net income was $63,000, or breakeven per share, compared with a net income of $1.7 million, or 1.2 cents per share a year earlier.
Revenue rose 11 percent to $24 million, about half of which came from outside North America.
Excluding items, the company earned a seventh of a cent.
Expenses for the quarter rose 28.3 percent to $18.4 million, driven mainly by a 63 percent hike in research and development spend.
Sandvine, along with rivals Bridgewater Systems Corp and Redknee Solutions Inc , has seen network congestion and greater use of smartphones drive up demand for its products and services.
