Details on the biggest ever 10GBE network test by Spirent and Juniper Networks.

1. BIGGEST EVER 10GBE NETWORK TEST
QFabric Validated by David Newman!
4X greater Performs, Scales, Interoperates & Simplifies
than previous
tests!
15.3 Tbps throughput at wire speed
(multicast traffic)
Layer 2/3 unicast forwarding delay1
<5usec for most packet sizes
Multicast latency <5usec for any packet
sizes
Interoperates with Cisco Switches
Nexus 7000 & Catalyst 6500-E
1,536 10GbE ports
Full mesh: Millions of traffic flows Entire data center managed as one
Extreme stress conditions logical switch!

 Forwarding delay:
 Close proxy for realistic latency measurements
 Measures how fast a packet can transit a switch under typical loads
 QFabric forwarding delay results2:
 Low latency across L2/L3 unicast & multicast
