Peering gives you greater control over routing, resulting in improved network performance and happy end users. In this fourth article in the “reasons to peer” series, we explain how this works.
When data is transported via public transit carriers, the data flows via a private network interconnect (PNI) between the involved carriers. PNIs mean cost, work, maintenance, and organization between those carriers, and upgrades of PNIs between large carriers do not always happen in time. Running your traffic over saturated PNIs can nevertheless work for a while, even without a noticeable latency or loss of quality – depending on the case.
