Cable operators globally recognize that tight networks simply work better, and signal leakage is the best way to detect, find, and fix the shielding weaknesses which let undesirable upstream ingress into networks. Leakage monitoring has adapted with the evolving HFC to remain feasible and maximize effectiveness, but the migration to a 204MHz upstream with high-split networks […]
As organizations seek to grow their business, the information they have access to grows as well. Meanwhile, increasing demands around data security put even more importance on having a proactive security solution in place. Organizations are striving to achieve revenue increases, accelerate digital transformations, and comply with regulatory mandates – all while keeping customer loyalties […]
Network observability is more than just the capture of wire data. True network observability means understanding the how and why of network performance in support of business goals – all while delivering the right data as actionable metrics. In the recent VIAVI Perspectives blog, 5 Steps to Network Observability Checklist, the critical and actionable network […]
Security frameworks such as MITRE ATT&CK™ are integrated with CyberFlood inherent capabilities, helping organizations assess the effectiveness of their security controls safely and continuously to gain insights into threat coverage across those policies. Proactive cybersecurity assessment may be one of the best defenses available against ever-growing cyber threats. One of the areas that has had […]
C-V2X introduces an entirely new dynamic with mission critical performance demanded from devices that are constantly moving, including between networks. Read how to design C-V2X testing strategies that will reduce time-to-market while delivering high-quality products. The promise of vehicle-to-everything (V2X) communications is to transform transportation. Improved safety? Better traffic efficiency? Cleaner environments? Expectations are high. […]
To keep up with the complex, hybrid networks of today, organizations must have a comprehensive network observability platform that embraces wire data, enriched and enhanced flow, and cloud sources to ensure optimal application delivery to stakeholders. That digital innovation requires a reliable and secure network foundation to deliver its promise – starting with basic observability. […]
Timing synchronization within and across datacenters is the lynchpin of 5G data integrity. Operators need to ensure the time difference between any two datacenter servers is accurate within 100 microseconds. Read about ways of avoiding inaccurate timestamps and meet regulatory requirements. We previously explored why this has been so difficult for datacenter operators, especially in comparison to […]
For mission-critical Industry 4.0 applications, even the smallest downtime is an absolute no-go. Learn how 5G and TSN systems work together to provide end-to-end seamless redundancy to increase the overall system availability and reliability. The new 5G system has been designed from the ground up, with many different verticals in mind, not just the enhanced […]
Synchronization testing of servers in a lab environment will not necessarily reflect the actual results in the field. Read why verifying synchronization in the live, working network is the only way to assure timing accuracy and performance. Obstacles to achieving 5G’s promised performance lurk around every corner. Let’s face it, distributed and disaggregated architectures that […]
Timing and synchronization is everything in 5G For a mobile network operator, timing is everything. Not just determining when to upgrade the network to bring new services to market, but in the literal sense as well. If the radio clock loses synchronization accuracy in a radio access network (RAN), or the radios are out of […]
