Discover how Megaport and Wasabi are expanding cloud object storage to support AI workloads, enterprise data growth, and predictable costs.

Learn how DDoS attacks work, how threats are evolving, and how modern network-integrated protection can help defend your infrastructure. Network connectivity is the frontline of revenue generation and customer trust for almost every modern enterprise. But as digital footprints expand across hybrid and multicloud environments, Distributed Denial of Service (DDoS) attacks continue to grow in volume, frequency, and sophistication.

Your dashboard shows every interface green, the counters look clean, and the application owner still insists the network is dropping their transactions. Where do you look next? Availability data tells you a link is up. It cannot tell you what crossed that link or how long the server took to answer. Only the packets carry that, and port mirroring is how most engineers get a copy without cutting into a live cable.

The Optical Transport Network (OTN) is a widely deployed industry-standard protocol that provides a comprehensive framework for multiplexing, switching, and transporting diverse digital payloads over optical fiber. Modern service providers face growing pressure to consolidate diverse traffic types. OTN acts as a universal digital wrapper, encapsulating Ethernet, IP, SONET/SDH, and storage (Fibre Channel) traffic into a single, highly efficient transport layer.

"This is the third slowdown at the regional offices this quarter. What is actually causing it, and what will it cost us to stop?" Questions phrased like that come from a business head rather than an engineer, and a dashboard screenshot will not answer them. Most network operations groups can produce evidence that something happened. Producing an explanation of why it happened, in language a finance director will accept, takes hours of manual correlation across separate consoles.

For years, IT teams had a fairly contained job: keep the office network running. Every device, router, and switch that mattered was inside a building they controlled. That job doesn't exist anymore. Remote and hybrid work moved the "network" into hundreds of living rooms, home offices, and coffee shops, none of which IT can see, configure, or troubleshoot directly. So when a help desk ticket comes in saying "the app is slow" or "my calls keep dropping," IT is left guessing. Is it the company's network?

What do you do when the switch carrying most of your traffic is the one device that cannot tell you what is on it? On high-speed core and data centre links, full flow export pushes device CPU past a comfortable line, so the export gets switched off and the busiest segment quietly becomes the least visible one. sFlow was built for that exact situation.
