Community dictionary

Dear Yuchen,

Could you please share the community dictionary used for validation? Thanks!

Best,

[yangtzeriverli]

Same need for this

[William394873]

@yangtzeriverli Caida has a public community dict, a bit obsolete tho

[yangtzeriverli]

@Guanlongwoo https://www.caida.org/catalog/datasets/bgp-communities/， Is this dataset you mentioned? This indicates the GEO location information but not business relationship, maybe I will check IRR record for business relationship community data.

[William394873]

@yangtzeriverli Yea, but imo bgp community itself does not record business relationships. You have to infer the relationship based on the community value (e.g., CAIDA AS-relationship serial 2), and the inferring algorithm itself is not accurate, to be honest.
I'm not sure why you need the community dictionary, but I would suggest directly visiting/crawling the public AS documents instead of IRR records. IRR is redundant and some of the records could be confusing.

[yangtzeriverli]

I want to use this for validation dataset in Problink paper. Visiting public AS websites or documents may be difficult, too much human labor as different website URLs.

@yangtzeriverli Then let's keep our fingers crossed and wait to hear from the author : ).

[yangtzeriverli]

OK, I have sent an e-mail to the author. Wait for reply, and I'll let you know as soon as I can

@yangtzeriverli Cool!

@yangtzeriverli Any updates? I'm curious about this community dictionary as well

[yangtzeriverli]

@jfuruness NO

Oof that's a shame. I emailed them as well just in case. I'd like to reproduce this paper, but without that dictionary it's pretty much impossible. Also - the code appears to hardcode in the tier 1 ASes in several places. Oh well, watcha gonna do lol
