By dealing with congestion dynamically and quickly, QFabric gets rid of the need to over design the network to accommodate it. That boosts network utilization to near 100%, Juniper says.

What are some numbers on how well this fabric performs?

The average data center – defined by IDC as having 3,000 servers – using QFabric rather than a traditional three-tiered architecture is six times faster, requires 22%fewer devices overall and incurs half the operating expenses.

Does this have implications for cloud architecture?

Yes, but not immediately. Juniper says that it will announce later a means to incorporate WAN connections into QFabric, making it possible to link dispersed data centers to support cloud services.
