Packet Pushers Podcast: Juniper’s PTX Platforms - 800GE and Double-Density 400GE for DC and WAN
Juniper’s PTX Platforms: 800GE and Double-Density 400GE for DC and WAN
The future has arrived: 800 gig Ethernet is here. Amit Bhardwaj and Dmitry Shokarev from today’s sponsor, Juniper Networks, join the show to tell us all about Juniper’s 800 gig Ethernet and what we need to know as engineers: use cases, transition plans, fiber, and power needs (a lot less than you’d think). We also go over the Juniper PTX router family that supports 800GE: line card specs, optics, the capacity for 2000km router-to-router lengths, etc. Finally, we dig into the Express 5 silicon that makes it all go. We talk about Juniper’s chip design philosophy, its use of chiplets, and its built-in features including line-rate MACsec, scalable SRv6, hierarchical QoS, Inline IPFIX, and more. Listen through until the end to hear Ethan ask the question he just can’t hold in: Does this mean 1T Ethernet is on the way?
