The cloud offers businesses a tantalizing vision of cheaper, faster, and more agile computing. However, the advent of global, hybrid, and multi-cloud environments has presented IT operations teams with a radically more complex infrastructure to manage. It has been ten years since Amazon first revealed that every 100 milliseconds of network latency cost them 1 […]
5G cloud, let’s demystify it What do we mean by the cloud? What are the different types of cloud environments? What parts of a telco business and network can be moved to the cloud today, and what are the possibilities for the future? VIAVI demystifies the cloud… In part I of our two-part blog, we […]
5G cloud, let’s demystify it: Part I What do we mean by the cloud? What are the different types of cloud environments? What parts of a telco business and network can be moved to the cloud today, and what are the possibilities for the future? VIAVI demystifies the cloud… Q: What links an online bookseller, […]
Advanced Upstream Blog Series Introduction In the Advanced Upstream blog series we will explore how cable operators have traditionally managed upstream bandwidth capacity planning, how market dynamics and technical innovation are driving changes, and where things are likely headed in the coming years. In this entry we will discuss the “More Bits/Hz” approach – or how […]
With the rollout of 5G, synchronization in carrier networks is becoming even more critical. Mobile cellular networks need to be synchronized to avoid base stations with shared coverage interfering and disrupting each other, leading to declining network quality for customers. Throughout the Third Generation (3G) cellular communications, the NodeBs relied on satellite communications for synchronization, […]
A global movement toward 800G has begun as operators and network vendors position to address new data demands. Read about how early test solutions are meeting an important need but must flexibly evolve with standards and overcome early complexity up and down the network stack. Though 400 Gigabit Ethernet (400G) is still working its way […]
VIAVI is honored to have received approval from the PCI Special Interest Group (PCI-SIG). The PCI-SIG® is a consortium of more than 800 member companies that owns and manages PCI specifications as open industry standards. This approval allows the VIAVI Xgig® Exerciser to be used for PCIe® Link and Transaction protocol compliance testing conducted by […]
By disguising the exploits at the point of delivery, malicious attackers can avoid detection, making security platforms and policies ineffective. Stay one step ahead of hackers with CyberFlood and CyberThreat Assessment. Malicious attackers are not necessarily all experts in malware manipulation, PowerShell, or other tools trying to constantly come up with new and innovative ways […]
Open Radio Access Network (O-RAN) is being adopted by service providers and equipment manufacturers to reduce infrastructure deployment costs and to lower the barrier of integrating innovative product developments. Read about the advantages and challenges emerging in that process, and how testing helps speed up O-RAN deployment. In O-RAN, the distributed unit (DU) is connected […]
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 […]
