While one can infer when a link is saturated by mapping network topology onto latency sampling, it can have on the order of 30% error, given that there are multiple causes of increased latency beyond proximal congestion. A question I commonly ask network engineers or academics is "How can I accurately distinguish a constraint in supply from a reduction in demand?" -- -- Jeremy Austin Sr. Product Manager Preseem | Aterlo Networks preseem.com Book a Call: https://app.hubspot.com/meetings/jeremy548 Phone: 1-833-733-7336 x718 Email: jer...@preseem.com Stay Connected with Newsletters & More: *https://preseem.com/stay-connected/* <https://preseem.com/stay-connected/>
