Bridges, tunnels, pipelines, telecom networks, electrical power transmission lines and other civil structures form the backbone of modern societies, facilitating essential services and connectivity. Ensuring the safety and integrity of these structures is of paramount importance. Thankfully, advancements in technology have led to innovative solutions for infrastructure monitoring, with fiber sensing technology emerging as a […]
Observability is all about leveraging diverse data sources, including flow, packet data, and metrics, to better understand what is happening inside the network, and what is likely to happen in the future. Therefore, it would not be surprising if more monitoring tools equated to more data and enhanced network observability, but that is not always […]
Observability is defined in mathematical terms as the ability to measure the internal state of a system based on only external information. On the other hand, monitoring is defined as a passive data collection process used to measure performance against predefined standards. In other words, network observability practices tend to be proactive, while monitoring tends […]

These PlugFests represent important, practical steps in developing the building blocks that will transform the network’s future. Radio testing is […]
Threat actors are leaning on Application Layer DDoS attacks to achieve their malicious goals. Learn how DDoS attack emulation can help validate cyber defenses and assess the performance and security posture strength of an organization’s networks and devices against these pervasive, destructive campaigns. DDoS Threat Landscape The latest DDoS threat landscape reports indicate that Application Layer […]
In the dynamic realm of data centers, AI is setting new benchmarks. A New Frontier for Data Centers AI models demand unprecedented bandwidth, driving data centers to transition from 400G to 800G, and eventually to 1.6T speeds. This rapid evolution is crucial for meeting the massive data demands. AI workloads differ significantly from traditional data […]
This is the third article in our three-part series on 5G synchronization. The first article focused on the transport layer’s crucial role in 5G synchronization, highlighting the importance of technologies such as GNSS, PTP and SyncE in ensuring precise timing and reducing latency across sprawling networks. It also discussed the implementation challenges and the need […]
In cybersecurity, quantum computing presents both exciting new possibilities and threats to data confidentiality, integrity and security. While it promises unparalleled computational power, it also poses a significant risk to current encryption methods, which rely on mathematical problems that could be solved on a quantum computer running Shor’s algorithm. As quantum computing advances, the urgency […]
As we continue our exploration of 5G synchronization in this second installment of our series, we shift our attention to the importance of synchronization in the radio access. The global rollout of 5G NR, predominantly employing TDD technology, underscores the necessity for all radios within a network to transmit in sync. This synchronization is crucial […]
VIAVI has spent decades testing Ethernet as a service, fueling its leadership position in testing modules, cables, and Ethernet ICs at the PHY layer. We also have products that cover the full stack to L7, offering breadth and depth of coverage. A few years ago, we determined current products on the market for high-scale Ethernet […]
