Talking Points

Recent interactions between the hosts and their guests.

Canonical Cache Representation
Q: What have you been doing here?
Job explains he started RPKI Views to capture all RPKI data and make it accessible in a structured fashion, enabling researchers and practitioners to reason about events and states in the RPKI ecosystem, and to derive insights from a long-term, reproducible data source.
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.
