[tor-dev] Relay diversity master thesis

[teor]

Hi Robin,

Sorry it's taken a while for someone to respond to your email.
Many of us have been on leave from the start of December until this week.

Please see my response below:

Have you considered relay bandwidth capacity, measured bandwidth,
consensus weight, or bandwidth authorities in your plan?

When using the Tor path selection algorithm, relay consensus weight has
a big impact on the paths selected by clients.

At the moment, relay consensus weight is a function of relay bandwidth
capacity, and geographic location. For a map of consensus weights, see
"Consensus Weight versus Bandwidth" on:

https://atlas.torproject.org/#map


Have you considered relay operators or relay families?
In particular, operators that could perform end-to-end correlation?

Have you considered the relay's Operating System?
Are you aware that the Tor network has historically been a Linux
monoculture, and 90% of relays still run Linux?

Have you considered the Tor version that the relay is running?

Recently, someone created a website that gave badges for different
kinds of relay diversity. But I can't remember what it was called.


I've also cc'd nusenu, who has done some work in this area.
