NetFlow, sFlow, and Flow Extensibility, Part 1

By Avi Freedman, Co-founder & CEO | Mar 28, 2016
Network Management, Technology

NetFlow and its variants like IPFIX and sFlow seem similar overall, but beneath the surface there are significant differences in the way the protocols are structured, how they operate, and the types of information they can provide. In this series we’ll look at the advantages and disadvantages of each, and see what clues we can uncover about where the future of flow protocols might lead.

Maximizing Network Metadata Value

By Jim Meehan, Director of Solutions Engineering | Mar 21, 2016
NetFlow Analysis, Network Management, Technology

The plummeting cost of storage and CPU allows us to apply distributed computing technology to network visibility, enabling long-term retention and fast ad hoc querying of metadata. In this post we look at what network metadata actually is and how its applications for everyday network operations — and its benefits for business — are distinct from the national security uses that make the news.

NetFlow Analysis, Network Management

In part 2 of this series, we look at how Big Data in the cloud enables network visibility solutions to finally take full advantage of NetFlow and BGP. Without the constraints of legacy architectures, network data (flow, path, and geo) can be unified and queries covering billions of records can return results in seconds. Meanwhile the centrality of networks to nearly all operations makes state-of-the-art visibility essential for businesses to thrive.

The Evolution of BGP NetFlow Analysis, Part 1

By Jim Meehan, Director of Solutions Engineering | Mar 7, 2016
NetFlow Analysis, Network Management

Clear, comprehensive, and timely information is essential for effective network operations. For Internet-related traffic, there’s no better source of that information than NetFlow and BGP. In this series we’ll look at how we got from the first iterations of NetFlow and BGP to the fully realized network visibility systems that can be built around these protocols today.
