1. In the traces I have, there exist several intervals with a huge, sudden increase of traffic on some links. The prediction model I use cannot predict those 'big spikes'. Do these 'big spikes' really happen in operational networks? Or are they merely measurement errors? If they really

Hi Deepak, Thanks a lot for your opinions! Especially, your idea that TE may be more appropriate to stub networks is very interesting. Is it a common practice of large transit ISPs to determine the pricing based on 'what the customer's traffic looks like and when'? And do the transit ISPs

Hi All, I'm a PhD student currently studying intra-domain traffic engineering, and I have two questions that I really wish to hear some opinions from you network operators. I'm experimenting with a prediction-based intra-domain traffic engineering technique. The technique uses traffic demand
