0:04 Today's AI data center rely heavily on
0:08 rocky B2 and DCQC for lossless Ethernet
0:11 fabric. The new demands are pushing the
0:14 limits. The ultra ethernet consortium is
0:18 redefining the scalability and aiming to
0:22 connect up to 1 million nodes with
0:25 faster ramp up for a workloads. It also
0:29 introduced a transport that understand
0:32 the AI specific communication patterns
0:35 with built-in semantics for
0:37 synchronization and reliable delivery.
0:39 We'll call it as a UE ultra ethernet
0:42 transport.
0:44 At in Tokyo 2025,
0:47 Juniper and Spyron showcased the
0:50 industry first ultra transport demo
0:53 using Juniper's QFX 5240 switch, which
0:57 is 64 into 800 gig capacity.
1:00 The test focused on UE packet
1:02 forwarding, validating a data center key
1:05 KPIs, and proving Rocky V2 and UE can
1:10 coexist.
1:13 A total of four Spiron ports drove both
1:16 Rocky V2 and U type of A workloads
1:20 through the switch as in realistic data
1:23 center setup.
1:26 Captured traffic show the new ultraet
1:29 transport headers including the packet
1:32 delivery sublays we call it as a PDS and
1:34 semantic subs called SCS just after UDP.
1:39 Both traditional and nextg a traffic ran
1:43 simultaneously on QFX 5240 switch
1:47 flawlessly.
1:49 Job ID tracking confirmed error fee
1:52 performance across both a workloads on
1:55 QFX 5240.
1:57 And yes, we won the award. The Ultra
2:01 Ethernet is real and Juniper is leading
2:04 the way.
