Cisco has agreed to acquire Growth Networks, which specialises in networking semiconductor design, for $355 million to beef up its terabit routing strategy.
The networking giant first outlined its terabit routing ambitions last December with the launch of a high-end GSR 12000 switch router that will eventually scale up to 5Tbps from an initial 360Gbps. Cisco began selling the 360Gbps GSR 12016 last December and promised to ship new products every 60 days for the next 12 months.
However, the company will now incorporate Growth's internet switching silicon design into the GSR range and high-end asynchronous transfer mode switch family.
Growth's switching fabric is made of networking silicon that interconnects the input and output ports within high-end switches and routers, said a Cisco spokesman. This enables them to scale from tens of gigabits per second to tens of terabits per second.
The key to Cisco's terabit strategy is the company's cross bar switch fabric architecture, which enables users to connect 10Gbps interface cards together to achieve terabit speeds.
