Network-Programmable Operational Flow Profiling
Alexander Clemm, Uma Chunduri · IEEE Communications Magazine · 2019
A detailed understanding of networks and network flows is key for many important operational problems, such as optimizing network performance, identifying causes of degradations or service-level fluctuations, and detecting security threats. However, gaining such insights remains a highly challenging task. This article presents a new approach for obtaining detailed behavioral and performance-related insights at the level of individual packets and flows, based on the concept of network-programmable operational flow profiling. Our approach leverages BPP, a novel networking framework which allows operational flow profiles to be programmed from the network edge without requiring heavy analytics and data collection frameworks.
