Network telemetry is far from new, but its importance is growing as data volume and network size relentlessly snowball. Streaming network telemetry gathers operational data from various network devices, combines the information, and then forwards it for inspection and study.
Growing scale and the increasing use of automation in next-generation enterprise networks require a modern, more efficient approach to network data capture and analytics, says Bo Lane, vice president of global engineering for Kudelski Security, a cybersecurity technology provider. “Streaming telemetry allows enterprises to track network state, identify network problems and optimize network performance,” Lane says. “In modern software-defined networks, problems or bottlenecks may be identified and autonomously remediated in near-real time.”
