Stolen from the article: > “So, essentially SCION is an architecture to provide an alternative to BGP”, Adrian started his presentation. “There are some principles which are quite different from the current Internet.” For example, the SCION architecture follows a stateless packet forwarding approach - i.e., there's no per-flow state in routers and thus no opportunity for inconsistent state. See an explanation of BGP here: https://www.cloudflare.com/learning/security/glossary/what-is-bgp/ https://www.cloudflare.com/learning/security/glossary/what-i.... So in my basic understanding of how the internet works, tl;dr SCION is a different way to transmit packets between computers, particularly over large distances.

In oversimplified terms, BGP is more like a routing mechanism between ISPs, rather than just computers. BGP has historically been problematic, as a misconfigured ISP could suddenly start broadcasting routes for eg YouTube which could bring that whole site down. (This isn’t a hypothetical example, this actually happened, see for example: https://news.ycombinator.com/item?id=122826 https://news.ycombinator.com/item?id=122826 )

  To expand a little more: BGP is a protocol for exchanging information about routes between routers, not a protocol for shipping non-routing data (e.g. your HTTP request is never carried by BGP).

    As a shitty analogy, I would say it's role is analogous to DHCP, except it's decentralized and for WANs instead of LANs.
