Talking Points

Recent interactions between the hosts and their guests.

The Erik protocol: improving RPKI data fetch
Q: What makes Erik different from RRDP and R-Sync in terms of data delivery?
Erik delivers deltas using a Merkle-tree-based three-phase model and fetches objects by hash, not by name, which reduces unnecessary data transfer and allows incremental, targeted updates with strong integrity guarantees.
The Erik protocol: improving RPKI data fetch
Q: So tell me, Job, did you come up with a better way of doing this?
Yes, I developed Erik synchronization, which combines the best parts of R-Sync and RRDP, uses a hash-based fetch model, and introduces intermediaries to avoid data monopolies while keeping final state accurate and efficiently verifiable.
What ‘name-based routing’ really means
Q: Why do open DNS resolvers raise privacy concerns in the context of geolocation-based routing?
Open resolvers can reveal a user's location indirectly through the source of the DNS query, enabling geo-targeted content delivery that leaks subnet information. This reduces privacy and can be exploited for geofencing or other controls, prompting the industry to consider attaching client address data, which itself raises further privacy issues.
What ‘name-based routing’ really means
Q: What are the main limitations or pitfalls of Anycast when used for content delivery at scale?
Anycast can deliver the closest instance in a coarse-grained way, but it often struggles with long, thin networks and large geographic spans, leading to suboptimal paths. It can also complicate operations if a single anycast address represents many servers, requiring additional mechanisms to reach a specific box for management or debugging.
What ‘name-based routing’ really means
Q: Geoff, how does name-based routing change the role of traditional IP routing in moving content closer to users?
Name-based routing replaces some of the purely location-based decisions with content and identity-driven steering, using DNS and application-level logic to pick a server near the user, while still relying on the network for transport. This allows faster, more efficient delivery but introduces trade-offs in caching, privacy, and interoperability across different providers.
