Due to security and compliance concerns, some vendors handling such sensitive data cannot expose services to the public Internet and therefore host their own on-premise data centers. For other vendors hosting services in on-premise data centers, there was no existing solution to connect.

As a result, Internet devices usually use a single path and let the routers handle the path selection. Enter Multi-Path TCP (MPTCP), which exploits the presence of multiple interfaces on a device, such as a mobile phone that has both Wi-Fi and cellular antennas, to achieve multi-path connectivity. There is another way.

This was what Kentik was all about at Networking Field Day 31. 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. More data!

To quote: “Today’s typical NPMD vendors have their solutions geared toward traditional data center and branch office architecture, with the centralized hosting of applications.”. You’d put a few others — I emphasize “few” because these appliances were and are not cheap — at other major choke points in and out of the network.

On a network, configurations are constantly changing. Unfortunately, configuration change accidents can happen that bring down parts of the network. Interface dropping packets. Interface issues caused by misconfigurations, errors, or queue limits lead to network traffic failing to reach its destination.

Meta is deploying a timing protocol, Precision Time Protocol (PTP) , that will offer new levels of accuracy and precision to our networks and data centers. We believe PTP will become the global standard for keeping time in computer networks. After a successful pilot, we’ve started extending PTP into all our data centers.
