Interesting/Notable things happening on BitSwap

[mrd0ll4r]

Hello!

I'm Leo, currently doing my PhD in Berlin on a bunch of things P2P.
We've been running some infrastructure to monitor data requests on BitSwap, see this v1 preprint on arXiv which will soon be updated with a new version.

Unfortunately, the interactive dashboard-esque results are not public (yet) and I'm still in the process of setting up some stuff to generate at least static images for public use somewhere.
Nevertheless, I occasionally talk about interesting recent events on BitSwap during one of the Demo Days or in the Slack channel.
In order to make that a bit more public and accessible, I'm opening this issue/discussion in which I'll post noticeable events or other quirks I've observed :)

[yiannisbot]

Thanks a lot Leo! Looking forward to your findings! It would be great to update us on the issue of increased Bitswap requests that we were seeing a few months back. When you get some figures showing the situation, please post them here too.

High Request Activity from 2021-06-12 to 2021-07-24

We saw a drastic increase in number of messages and number of wantlist entries from 2021-06-12 to approx. 2021-07-24.
I'm attaching two Grafana snapshots to illustrate the situation:

Wantlist Entries Received/s:
https://snapshot.raintank.io/dashboard/snapshot/9mLS3lzTm5sjiu68yFAcZACU0CWXnUOL

Wantlist Messages Received/s:
https://snapshot.raintank.io/dashboard/snapshot/LkAWa8GcOYvCjMRq28TQJe2J1OKP7KQy

Notably, we received much larger messages than usual, i.e., they contain more entries than usual.
The number of peers stayed approximately the same during the first half of the elevated activity, but increased in the second half after a longer downtime of the monitoring node due to having ran out of disk space. It's unclear why the number of peers increased after that, but this did not affect the recorded request activity in a visible manner.

Analysis

I did some analyses on the traces collected for one weekend (I believe it was from 06-18 to 06-21, but not 100% sure anymore) due to the size of the traces.
This showed a few interesting things:

Daily Unique Requested CIDs

We're always calculating how many new unique CIDs we're seeing per monitor per day.
That number is usually 1M-2M
It went up over the weekend, but by far not as much as the increase in number of requests would cause:

2021-05-25: 2290908
2021-05-26: 2079976
2021-05-27: 2732208
2021-05-28: 2331505
2021-05-29: 1943922
2021-05-30: 1929157
2021-05-31: 1662226
2021-06-01: 2128908
2021-06-02: 1687188
2021-06-03: 1583134
2021-06-04: 1579809
2021-06-05: 1593040
2021-06-06: 1658002
2021-06-07: 1690743
2021-06-08: 2141701
2021-06-09: 2552882
2021-06-10: 1604839
2021-06-11: 1716114
2021-06-12: 1822630
2021-06-13: 2341337
2021-06-14: 2098134
2021-06-15: 2543423
2021-06-16: 2544900
2021-06-17: 4240623
2021-06-18: 3333499
2021-06-19: 3041743
2021-06-20: 2630747
2021-06-21: 3358324

=> They request old content? Maybe, or maybe 2M "new" CIDs, but.. meh. Unclear.

Number of Requests by Peer ID

Number of request entries (excluding CANCELs) by peer ID, top 100 or so.
Unfortunately I did not have the time to plot the distribution and compare that to a "normal" weekend.

Information about Top Requesting Peers

IP addresses and agent versions for top 25-ish requesting peers.
I checked these via MaxMind's GeoIP Database and they are, with one exception, all Chinese.
The one exception is a Russian IP.
This is very different from the usual distribution we're seeing, which comes mainly from NL, US, DE (see paper).

Requested CIDs

Number of requests per CID
It's possible this was not calculated over the entire weekend but rather just one day, I'm not sure anymore.
Either way, we don't see any specific CID being requested millions of times, but rather many CIDs being requested a few times.
Unfortunately I did not have the time to plot the entire distribution and compare that to a weekend of "normal" activity.
