Consider SD-WAN as another example of DoH causing problems. The SD-WAN controller grants permission to connections based on the top-level domain (e.g., If Google has their druthers, a lot of SD-WAN vendors are going to be in a tough spot and will have to figure out another way to enforce policy. facebook.com) being visited.

Synthetic testing is done by sending synthesized tests that are not from real users to check availability and performance metrics, such as latency, jitter and packet loss. internet, cloud, WAN, data centers, etc.) Site-to-site performance across traditional WAN and SD-WANs.

Ping and traceroute tests performed continuously with public and/or private agents generate key metrics (latency, jitter, and loss) that are evaluated for network health and performance. The Network Explorer combines flow, routing, performance, and device metrics to build the map and let you easily navigate.

We believe a data-driven approach to network operations is the key to maintaining the mechanism that delivers applications from data centers, public clouds, and containerized architectures to actual human beings. Ultimately, we’re solving a network operations problem using a data-driven approach. More data!

When evaluating solutions, whether to internal problems or those of our customers, I like to keep the core metrics fairly simple: will this reduce costs, increase performance, or improve the network’s reliability? It’s often taken for granted by network specialists that there is a trade-off among these three facets.

This could mean the users are saturating the internet connectivity or that they’ve saturated the LAN (or maybe WAN). We also collect interface details and metrics using SNMP. This data is useful for Kentik’s automated capacity planning workflows and building topological maps (layer 2 and layer 3 connectivity).

Using a synthetic test, we can capture the metrics for each component of that interaction from layer 3 to the application layer itself. This isn’t necessarily a bad thing, but it isn’t the same as collecting metrics on the application’s activity itself. This is common in service provider networks and for data center core devices.
