BGP / routing paper recommendations?
by Casey Callendrello 02 Feb '21

02 Feb '21

Hi all, I'm part of a paper reading club, and the group's interest has turned to BGP and Internet routing in general. As the only person in the group who even knows what an AS is, I've been tasked with finding interesting papers on the subject. Any papers or presentations that you found valuable or interesting? My list, so far: - ARTEMIS: Neutralizing BGP Hijacking Within a Minute (https://www.inspire.edu.gr/wp-content/pdfs/artemis_TON2018.pdf) - Securing BGP - A Literature Survey (https://ieeexplore.ieee.org/document/5473881) - Stable Internet routing without global coordination (https://ieeexplore.ieee.org/document/974523) - A Survey on Approaches to Reduce BGP Interdomain Routing Convergence Delay on the Internet (https://ieeexplore.ieee.org/document/7964680) I would particularly appreciate papers that focus on the distributed-systems aspect of routing, such as convergence times, stability, and security. Happy to take responses off-list, will summarize in due time. TIA, -- Casey Callendrello

01 Feb '21

Does anybody know if there's an alternative to Any2 Los Angeles with predictable uptime and enough members in LA? It's the second outage this month and we've observed at least 7 outages in the past year and we didn't even receive any maintenance notice or RFO. -- Siyuan
