Vendor market shares of the Service Provider Edge Router market encountered several changes during the first quarter of 2010. 
“As the Service Provider Edge Router market recovers this year, a number of variables is affecting the vendors’ performance,” said Shin Umeda, Vice President at Dell’Oro Group. “For example, Cisco is benefiting from its large, global customer base and new product cycles, while Tellabs, a much smaller company, is seeing strong demand for its products in wireless networks,” added Umeda.
