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 wrap up the HFC Advanced Upstream discussion, […]
Every network and application brings unique characteristics and vulnerability to network impairments. Having a deep understanding of how apps behave in a range of expected scenarios is a critical step in assuring performance. Read how pre-deployment testing and verification will help relieve doubts and reveal the unknown. A perfect storm of tech readiness, big data […]
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 Hz” approach – or […]
Speed and security requirements now go hand in hand. Can your tools and testbeds keep up? The pace of tech advancement has officially reached breakneck speeds. 5G, IoT, SD-WAN, SASE and 800 Gigabit Ethernet are just a few of the technologies ushering in not just new possibilities, but new demands. Standards bodies are racing to […]
The demand for data is growing exponentially and the datacenters need to keep pace. RoCEv2 has proven its usefulness over TCP/IP by providing the lowest latency by far in a legacy Ethernet datacenter. Optimization will be key to achieving the best results in large scale deployments. In today’s world, a speedy transfer of data is […]
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 […]
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 […]
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 […]
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 […]
