Sure. By "trident" I really mean any merchant silicon switching platform. The Broadcom Trident ASIC/chipset really kicked this market segment off in 2011/2012ish. I mentioned it specifically as products like the Juniper QFX3500 series really opened up the door for things like fat/high radix clos networks that we're seeing in production. From memory the Trident boxes supported 640gbs of throughput on SFP+ or QSFP ports, about 10,000 prefixes/routes, a couple thousand ACL terms, 1 or 2u, and around 200watts. They cost maybe $20,000 at launch are down to $5-10,000 now depending on volume and vendor. That's great for a TOR or agg switch if you can manage the individual devices (as opposed to a switch chassis like a nexus 7K). The other thing those really opened up is cheap as chips edge devices. 10,000 routes isnt a lot, but it works if you have limited peers or can do summarization off device like a route reflector. These chipsets, and trident in particular, also work great with things like OpenFlow as you move that expensive route computation off device to a specialized platform. The trident platform is basically EOL'd, everyones moved on to Trident II for the most part. Trident II is like 100,000 prefixes, 50,000 ACLs, 1 or 2u, 200 to 400 watts, 1.2TBs of forwarding, and SFP+/QSFP ports. Price is $15-25,000 depending on volume and vendor etc. Pushing 640gbs of throughput for ~$20,000 is pretty crazy. It means I could build a single 10kVa server rack that pushes a legit…

I'm sorry, but you are dead wrong. I would go so far as to say this is the standard informal/slang way to distinguish rotating magnetic media from optical/solid-state media, and off the cuff I'd say it has been since the advent of consumer optical media about 30 years ago. A definition from a decade and a half ago: https://etherealmind.com/network-dictionary-spinning-rust/ From 8Y ago: http://www.dba-oracle.com/t_spinning_rust.htm It's in Wiktionary: https://en.wiktionary.org/wiki/spinning_rust And Urban Dictionary: https://www.urbandictionary.com/define.php?term=Spinning%20Rust

Interesting writeup here: https://etherealmind.com/ethernet-jumbo-frames-full-duplex-9000-bytes/ It claims that CRC32 is sufficient to detect errors in frames as large as 9000 bytes.

I definitely wasn't asking for maximum packet size, which a search feature showed in huge print as the answer to my question. I don't expect the search algorithm to know my precise intent, but I'd like it to weigh the word "typical" highly. Between google, bing and duckduckgo, only duckduckgo presented this above the fold: https://etherealmind.com/average-ip-packet-size/

> spinning rust TIL https://etherealmind.com/network-dictionary-spinning-rust/ > Spinning Rust – term for conventional hard disk drives with motors and using ferrous-based platters for data storage. Probably derogatory now that Flash Drives are beginning to replace conventional drives.

I remember as the average packet size on the internet. Googling average packet size yields that- https://etherealmind.com/average-ip-packet-size/
