Packet Loss is the #1 Performance issue in Networks Today


Analytic Data vs. Surveys Survey Says Get 10GB

“10 Gigabit Ethernet Port Shipments Exceed 2 Million During 2009 ”

“The report also shows that 10 Gigabit Ethernet (GE) was the only market segment to show sequential port and revenue growth in 2009, due in large part to shipments of purpose-built fixed 10 GE boxes for the data center. The majority of market revenue growth in 2010 is also forecast to come from these 10 GE product”– Dell’Oro Group
