After over a decade of research on Quality of Service (QoS) among @Anapaya Systems, @ETH Zürich, and @Mysten Labs, the SIBRA and Colibri systems have been designed. The new system, 𝗛𝘂𝗺𝗺𝗶𝗻𝗴𝗯𝗶𝗿𝗱, is the final step on this journey, offering 𝙜𝙡𝙤𝙗𝙖𝙡 𝙝𝙞𝙜𝙝-𝙥𝙚𝙧𝙛𝙤𝙧𝙢𝙖𝙣𝙘𝙚 𝙌𝙤𝙎 𝙤𝙣 𝙩𝙝𝙚 𝙎𝘾𝙄𝙊𝙉 𝙣𝙚𝙩𝙬𝙤𝙧𝙠. 📄 Read the paper: dl.acm.org/doi/10.1145/37189… 🎥 Watch the talk: youtube.com/watch?v=9unwqHEh… We anticipate to roll out Hummingbird on production networks in 2026, which is very exciting as this will be the first global availability of QoS after 30 years of effort in this area. Thanks to Hummingbird, we can achieve communication guarantees on a public Internet despite DDoS and routing attacks. Numerous applications will be enabled, such as telesurgery and critical infrastructure command-and-control: over a public Internet! #SCiON_Network #SCiON_Internet_Architecture #networksecurity #scioninternetarchitecture #scionnetwork #cybersecurity #nextgeneration #internet #QualityOfService #NetworkPerformance #PathAwareNetworking
