Classification

Node classification:

• dangling - A peer that was seen going offline and online during the measurement period (potentially multiple times)
• online - A peer that was not seen offline at all during the measurement period (always online)
• offline - A peer that was not seen online but found in the DHT during the measurement period (always offline)
• entered - A peer that was offline at the beginning of the measurement period but appeared within and didn't go offline since then
• left - A peer that was online at the beginning of the measurement period, did go offline and didn't come back online

Crawl Time Series

The top graph shows the number of dialable and undialable peers for each individual crawl. Further it shows the sum of both as Total.

The bottom graph shows the percentage of dialable peers in each crawl (Dialable / Total)

Agent Version Analysis

Overall

These graphs show the agent version distribution that was observed during crawling the network. The number next to Total indicates the number of successful crawl visits that contribute to the distribution.

Dangling Nodes Only

These graphs show the agent version distribution that was observed during crawling the network of only the dangling nodes. The number next to Total indicates the number of successful crawl visits that contribute to the distribution.

Online Nodes Only

These graphs show the agent version distribution that was observed during crawling the network of the nodes that were online the whole measurement period (very stable peers). The number next to Total indicates the number of successful crawl visits that contribute to the distribution.

Latencies

Overall

Connect measures the time it takes for the libp2p host.Connect call to return. This involves several hand shakes under the hood (includes the dial duration as well).

Connect plus Crawl includes the time of dialing, connecting (as explained above) and crawling the peer. Crawling means the time it takes for the FIND_NODE RPCs to resolve. Nebula is sending 15 of those with increasing common prefix lengths (CPLs) to the remote peer in parallel.
