SCION looks very promising, and by now it has also been deployed in Switzerland's financial network, so it seems ready for production:

(Actually, the original creator of SCION teaches my CompNet course, which is pretty cool. His rants on BGP are quite legendary.)

>"His rants on BGP are quite legendary"

I'm assuming the context of these is lectures? Are they online anywhere? If not could you share what specifically about the protocol they feel so strongly about?

Indeed, he talks about BGP and SCION in the lectures. Sadly I think the lectures aren't available to non-students. What is available though are explanatory videos by him (Adrian Perrig) on the SCION website, where he talks about the issues BGP has: https://scion-architecture.net/pages/videos/

The tl;dw is that today's internet has comparatively poor availability, packet paths can be hijacked and there's little transparency in routing. SCION sets out to solve these problems, and has a few nice things in store, such as guaranteed bandwith between two hosts making DDoS attacks much less effective (COLIBRI QoS), or an incredibly high throughput packet filter (LightningFilter).

Thanks for the link, this is great. Cheers.

I gave up when I saw new packet headers which means you might not be able to use existing ASICs.
