NetFlow Protocols and Applications
"NetFlow Protocols and Applications" "NetFlow Protocols and Applications" offers a comprehensive and authoritative exploration of flow-based network monitoring, guiding readers through the evolution, operation, and powerful use cases of NetFlow and related protocols. Beginning with the foundational concepts—contrasting flow- and packet-based approaches, explaining the role of metadata, and mapping the architectural components of modern flow monitoring systems—the book provides a holistic view of the flow paradigm. Readers will gain a deep understanding of the technical distinctions between protocols such as NetFlow v5, v9, IPFIX, and sFlow, as well as how these are used for traffic engineering, forensic analysis, and anomaly detection in contemporary networks. Moving beyond the basics, the book delves into the design and deployment of flow systems, from exporter internals and sampling techniques to scalable collection architectures and advanced storage solutions. Practical guidance is provided for interpreting flow records, retaining data for compliance, and achieving high availability and disaster recovery. An extensive section on advanced analysis showcases how flow data can be enriched with contextual intelligence, modeled for traffic patterns and behaviors, processed at scale using modern data pipelines, and integrated with security event management platforms—empowering network professionals to visualize, automate, and secure today’s complex environments. Designed for both practitioners and architects, "NetFlow Protocols and Applications" addresses critical security and compliance challenges, including DDoS detection, forensics, and privacy in the era of encryption and regulatory mandates. The book concludes by surveying the future landscape: the application of machine learning to flows, the impact of IoT and edge computing, integration with SDN and NFV, and the promise of open-source innovation. Thorough, up-to-date, and rich in real-world insight, this volume is an indispensable resource for anyone responsible for monitoring, securing, and optimizing modern networks.

Despite the explosion of networking services and applications in the past decades, the basic technological underpinnings of the Internet have remained largely unchanged. At its heart are special-purpose appliances that connect us to the digital world, commonly known as switches and routers. Now, however, the traditional framework is being increasingly challenged by new methods that are jostling for a position in the “next-generation” Internet. The concept of a network that is becoming more programmable is one of the aspects that are taking center stage. This opens new possibilities to embed software applications inside the network itself and to manage networks and communications services with unprecedented ease and efficiency. In this edited volume, distinguished experts take the reader on a tour of different facets of programmable network infrastructure and applications that exploit it. Presenting the state of the art in network embedded management and applications and programmable network infrastructure, the book conveys fundamental concepts and provides a glimpse into various facets of the latest technology in the field.
The ntop/ipflow system
Ntop will tell you the truth about network traffic and it will draw it nicely. A description of Netflow mechanism implementation in the Linux system on the basis of the ntop program and the nProbe probe. The ntop program is an application doing the tasks of the network probe enabling visualization of using the network. The application work is similar to the work of the popular top application showing the work of processes in the system. Keywords: ntop, nProbe, probe NetFlow, flow statistics, network analysis
