QFabric

QFabric is a proprietary technology proposed by Juniper Networks. Its goal is to simplify the traditional tree architecture of L2/L3 switches to a single tier any-to-any connectivity. In its QFX3000-M QFabric System, which supports up to 768 10GbE ports, the average end-to-end latency can be as short as 3 microseconds. In QFX3000-G QFabric System, which supports up to 6,144 10GbE ports, it can achieve an average port-to-port latency of 5 microseconds.

QFabric System Components consists of:

• QFabric Nodes - fixed-configuration edge platforms that connect to networked data center devices
• QFabric Interconnect - a high-speed transport device that connects all QFabric Nodes in a full-mesh topology
• QFabric Director - which provides control and management services for the full QFabric System

Competitive technologies to QFabric include IEEE 802.1aq, MC-LAG, VXLAN, and the IETF TRILL standard.
