That network now essentially allows Google to treat all computing resources within a single data center as one giant computer. “This means that each of 100,000 servers can communicate with one another in an arbitrary pattern at 10Gbps,” he said.
The architecture also tries to manage all the resources, everywhere on the network, as part of a single computing fabric.
“Our latest-generation Jupiter network has improved capacity by more than 100x relative to our first generation network, delivering more than 1 petabit/sec of total bisection bandwidth,” said Vahdat.
Google released four papers that details various aspects of its networking architecture, including its reliance on software defined networks.
