5 Gbps is pretty slow. Internet carrier routers typically connect to each other at 100 gbps (or 400 gbps these days) and a single router will have many such connections, so Tbps of bandwidth, often costing about the same as that IPS FPGA hardware (well, the routers go up to rack size in which case you'd probably want to compare to a rack size IPS box cost).
- wmf 3y agoYes, analyzing hostile traffic is much more expensive than routing.
- zamadatix 3y agoWell yes, you could gather that, but also highlighting that what inspection boxes do in regards to F&R does not necessarily relate to the problems covered in the article because F&R has to work extremely quickly across the internet, often ruling out anything related how the box in the middle could see it and instead being about what endpoints can do independently via things like DPLPMTUD instead. The boxes do run into very interesting problems and knowledge space though, just more on the inverse of the problem at hand (how to properly act like a client receiving already fragmented data).

- egberts1 3y agoThere is a 25Gbps XNS in the work. With even more live updating of newly added Aho-Corrasick and Regex algorithm into the FPGA.
- zamadatix 3y agoOh yeah, things can still scale up but the gap ends up remaining the same as the same scaling drives each. Fortinet does some really insane stuff scaling its custom ASICs (+some FPGA, but it's not fast enough for everything so most is in ASIC instead) on e.g. the FG-7121F chassis to get ~500+ Gbps IPS/NGWF throughput. I haven't had excuse to go past their "smaller" fixed platforms which do 40+ though. Naturally you're paying more for that single 500 Gbps (total), of which elephant flows are limited because that's via parallel flow processing, than you would for something like a Nokia 7750 SR-s with ~500x (216 Tbps) that throughput though but such is life when you need to act as an endpoint instead of a router.
- egberts1 3y agoOops, maybe we can add massively parallel FPGA processors should be in there somewhere before the SSL stage. Goal is to do proper reduction of each ASIC/FFPA stage without a packet drop. Meanwhile, your website is dropping SSL connections, zamadatix.
