Juniper Networks reported fourth-quarter revenue was up 14 percent to $923 million, and full-year revenue was up 26 percent to $3.57 billion. Quarterly income was $132 million, and yearly income was $511 million, both significant improvements.

Customers in Q4 included Singapore Telecommunications (SingTel), which is using Juniper's security solution, and Internet Initiative Japan, which deployed Juniper's Ethernet services routers.

Juniper said it also gained traction with its M- and MX-series products, with customers including Deutsche Telekom, Telenor and Telecom Italia.

New customers include Divona Telecom, a satellite and WiMAX telecom operator in Africa, which selected the MX-series Ethernet Services Routers to create a high-speed, service-enabling backhaul network.

Kevin Johnson, chief executive officer of Juniper Networks, said: “Even in this tough economy, we managed to grow year-over-year quarterly revenue by 14 percent and non-GAAP diluted earnings per share by 19 percent . We continue to play offense and grow market share, while at the same time taking action to responsibly manage our cost structure. The long-term growth fundamentals of high-performance networking remain strong, and by strengthening our product portfolio and focusing on the customer, Juniper is positioned for accelerated growth once market conditions improve.”
