Yep, the microwave links are often using custom layer 3 tech (1 byte messages!).
Beyond that, you need to vertically integrate a hardware shop and get custom layer 3 hardware, otherwise you're not going to beat off the shelf Arista/Cisco switches doing IPv4 routing.
Also, at the end of the day, you need to be shipping your bytes to an external consumer (e.g. an exchange), so you're probably going to need to have an IPv? layer at some point anyways.
- organsnyder 8y agoIt's crazy the lengths to which trading firms are going to squeeze nanoseconds out of latency. It makes me wonder what value we're getting, from a societal perspective.
- Misdicorl 8y agoBetter network tech =). You can probably thank trading for consumer 10G now and 40G in ~5 years.
- amluto 8y agoI doubt that’s true. HFT is big business but nowhere near that big. Keep in mind that a lot of the big HFT players failed a few years back due to revenues being too small to support the R&D operations. I think that what really made 10G affordable is trickle-down from the SAN world.
- Misdicorl 8y agoYeah you're right, above is a bit sensationalized. I think it still probably had a (positive) impact on pricing and time to market though
- blackflame7000 8y agoYea you can pick up a PCIe 10G adapter for $40 on Amazon and a 4 port 10gb dlink switch for $200
- blackflame7000 8y agoIt's all about finding and capitalizing on arbitrages in the market the popup and disappear all the time in the blink of an eye.
