Howdy,
Keep in mind I am basing this 'idea' off of fixed orbit's data which can so=
metimes be a bit out of date, etc.
(in theory, and based upon number of peers, data): If you have a network wi=
th these upstream connections to the Internet you should see inbound traffi=
c utilization in this order:
AS Name
---------=20
3356 Level3
7018 ATT
3549 Global Crossing
4323 Time Warner Telecom
10796 TimeWarnerCable/RR
I am trying to determine why I am seeing it in this order:
3356 Level3
4323 Time Warner Telecom
3549 Global Crossing
10796 TimeWarnerCable/RR
7018 ATT
I suppose there is a certain level of convergence where these providers int=
er-connect, and also the source network of the traffic plays a big part of =
it, i.e. if most of the sources are directly connected to Level3, etc.
I am mainly wondering why 7018 sends us such a little amount compared to ev=
en 10796.
Also, with the providers already connected, if we added a new one, which on=
e would (in your opinion) benefit us the most on spreading the inbound traf=
fic out better?
I realize that we can use communities, and prepends to control the inbound =
flow, I am just speaking from a purely natural standpoint.
thanks,
-Drew
