It's not just the immense traffic throughput, but also consider that some of these routers [0] can do line-rate MACsec encryption at 400Gbps on every port.
This kind of horsepower was unthinkable even a few yrs ago...

Can you explain what the advantages of a 25gbit network are?
It’s the next step up from 10G (which our peak traffic is outgrowing).
If you look at older/used networking gear, 40G QSFP+ might look like the next step, but to me that’s starting to look a bit like an evolutionary dead end at this point.
Low-end 25G routers/switches are relatively cheap, as are 25G SFP28 optics (including bi-directional ones, which get a bit marginal at speeds above 25G).

I guess what I'm really asking is: what are you doing that requires so much bandwidth?
The traffic volumes these devices are intended for are truly mind-boggling to me (as someone currently building a small 25Gbit network with sub-$1k parts).
