The use of metadata is nothing new – ancient Egyptians deployed this concept over 2,000 years ago, using descriptive tags to organize and summarize voluminous, hand-written scrolls. In the digital age, metadata has taken on new meaning and significance, as NetOps and SecOps teams seek out more efficient ways to garner valuable insights from an […]
I’ve been in RF optimization long enough to see it evolve from something very manual and field-heavy into something that is now increasingly driven by data and AI. When I look back, the fundamentals haven’t changed, but the way we approach them has evolved in ways I wouldn’t have imagined back then. I started my […]
A New Chapter for Network Validation Network testing has always depended on expertise. Whether validating a new data center fabric, benchmarking network equipment, or verifying application performance and security, engineers have traditionally needed deep knowledge of test tools, APIs, and product-specific workflows. As networks become larger and more complex, especially in AI-driven environments, that expertise […]
Quantum computing poses a serious threat to current encryption standards, driving organizations to prepare for the post-quantum era. In this blog, we outline how rising risks are reshaping testing, performance planning, and cryptographic transition strategies. Why Today’s Encryption Isn’t Ready for Tomorrow Encryption has long safeguarded data privacy, with algorithms like RSA-2048 built to resist […]
It is rush hour in a busy city center. Thousands of smartphones are moving between cells as commuters leave offices and head home. Across the network, an AI-powered xApp is making real-time decisions about which radios can be powered down to save energy, and which need to remain fully active to handle demand. These decisions […]
VIAVI powered by NVIDIA accelerates the path to autonomous networks Ahead of DTW Ignite 2026, Copenhagen Transport and IP networks are the connective tissue of the entire service stack. The packets that move between a cell site and a datacenter, an enterprise and the cloud, a subscriber and a CDN node, traverse this layer. Think […]
Telecom operators already know the problem. Networks have grown too complex, too layered, and too interdependent to manage through observation and reaction alone. The window for human intervention, between a condition emerging and a service degrading, has narrowed to the point where manual operations are no longer a viable model at scale. The industry has […]
Avnu Alliance Spring Plugfest is a central event in the development of interoperable, low-latency, high-reliability networking standards. VIAVI is a key member of the Avnu Alliance, contributing to testing events, governance, and the ongoing evolution of Time-Sensitive Networking (TSN), including leading test plan development for standards such as IEEE 802.1CB and 802.1Qci. As TSN adoption […]
If there is one aspect of AI that challenges high-bandwidth networking more than any other, it is training. However, with the growth of applications that depend on inference performance, inference is quickly catching up and placing even greater strain on the network. Compounding this are rising usage volumes, test-time scaling, mixture-of-experts architectures, and the use […]
The lack of strength of GNSS signals at the end of their journey from a satellite makes them highly prone to interference. The RF power level of a GPS or Galileo signal, for instance, is below the thermal signal floor by the time it reaches the earth. Interference techniques are being used widely, especially around […]
