[j-nsp] Qfabric

[Stefan Fouant]

It's more than just a competitive offering to compete with the likes of the Nexus switches from Cisco, and its also quite a bit different from Cisco's FabricPath or other similar TRILL offerings. With FabricPath and TRILL we solve the problem of wasted revenue ports associated with complex 3-Tier architectures and blocked Spanning Tree ports, but you still have a forwarding table lookup taking place on each node along the path. With QFabric we have a set of devices which combine to form a singular unified fabric, all sharing a single control plane and managed via a single pane of glass, but more importantly achieving reduced latency as a result of a single forwarding table lookup taking place on the ingress node. With such a configuration we can achieve end-to-end Data Center latency on the order of 5 microseconds.

There is a lot more to it which is obviously covered in the whitepapers, but this is truly something which is going to revolutionize data centers as we know it for some time to come.

Its junipers answer to nexus 5k 2k soltuion with larger scalability
essentially.
It has a big fabric interconnect at the core and some routing engines that
control edge switches acting like remote line cards.
