Part of the challenge of determining the routing resilience of the Internet is the difficulty in getting an accurate understanding of the actual routing infrastructure. Several groups have measurement efforts underway:
- BGPMon – monitors BGP updates and routing tables
- AS Rank from CAIDA – provides size rankings of networks (Autonomous Systems or “AS”s)
- CIDR Report – statistics related to size of routing table, changes to routes, bogons and more
- Route Views Project from the University of Oregon
- RPKI Deployment Monitor from NIST – provides a series of views into prefix/origin validation using RPKI both globally and for individual Regional Internet Registries (RIRs)
Additionally, there are several projects undertaking large-scale Internet measurement that are actively seeking additional participants:
- CAIDA’s Archipelago (Ark) Measurement Infrastructure
- RIPE NCC’s Atlas network
- Internet Society’s Routing Resiliency Survey (RRS) – for more information you can also see our posts on the Deploy360 blog and on the Internet Technology Matters blog.
