back to article Cisco's latest switch packs 32 800G ports into a pizza box

Cisco this week unveiled one of its highest performance and lowest form factor switches yet – a diminutive 1RU pizza box packed with 32 800Gbit/sec ports – at the Open Compute Platform Summit in San Jose. Do you need 800Gbit/sec networking? Probably not – unless you're at webscale, hyperscale, or your enterprise is really gung …

    IEEE 1588v2 and SyncE support with nanosecond-level accuracy

    "1588v2 and SyncE support with nanosecond-level accuracy" - I guess that can be used for flow records, so we can timestamp better than ever, for fingerprinting devices, tracing Tor and VPNs, etc. For looking at side channel information from the operating system or CPU clock? I wonder what use intelligence agencies might find for that... Just speculating, it's not really my area of expertise.

    Nowadays the majority of backbone router on the Internet are spies, collecting our flow data to send off to Team Cymru??? When every single router is an informant for the government and God knows what other third parties?

    Here's a video on Team Cymru's flow based threat detection:

    I guess "threat detection" includes data which will be used for prosecuting people committing the "offence" of watching certain types of cartoon Japanese pornography... And ultimately putting these people on the Sex Offenders Registry, for looking at cartoons, which is insane. Perhaps those doing so using Tor. And VPNs as well.

      Alright, mate, we don't need to know what kind of porn you watch.

      Telcos still have a lot of SONET/SDH carrying everything from T1's to STM's. All those S's stand for SYNCHRONOUS and none of it works without precisely sync'd clocks on both sides of the link. Now that more and more POPs are being interconnected with Ethernet, these protocols allow for that. Precision timestamping is also useful for packet dedupe, chronoology, and correlation at an ASIC-level scale. I.e., to identify causes of microbursts and incast collapses.

      Lop off about five or six orders of magnitude in precision and you'll get to human-scale porn monitoring of the type you're talking about.

    The last time I saw that kind of capacious port density...

    was in a dream I had about meeting Nelson at an Admiralty reunion dinner!

    too slow to market Cisco! Nokia has 800GE running live already...
