Basic traffic engineering for maximising peering traffic

Hello world from Gujarat! This is my 3rd visit to Gujarat. :)

Coming to today’s post: I have noticed ISPs doing really crazy things to maximise traffic on peerings and IXPs. Some of those are bad and some are very bad. Additionally I came across this comment and thought to put this quick post.

 

Example of some bad ways to increase IXP traffic:

  • Using upstream’s ASN to keep AS path shorter (yes, believe me I have seen that!)
