At what point do commercial ISPs upgrade links in their backbone as well as peering and transit links that are congested? At 80% capacity? 90%? 95%?
I've worked for employees where policy has been anywhere from 50% or 80%. And I know this isn't complete range. Most do not subscribe to any single simple rule but act more tactically. Personally if the link is in a growth market, you should upgrade really early, 50% seems late, cost is negligible if you anticipate growth to continue. If it's not a growth market cost may become less than negligible. Sometimes networks congest particularly their edge interfaces strategically due to poor incentives, where irrelevant revenue wholesale arm might see some benefit from strategic congestion while also significantly hurting their money printing mobile arm reducing company wide bottom line while improving wholesale arm bottom line. -- ++ytti
