FROM THE INDUSTRY
the subscriber’s application — whether gaming, video messaging or virtual reality headset — through the CMTS and the operator’s network, all the way to the gaming server. This approach provides a genuinely differentiated subscriber experience with consistent low lag service performance.
Intelligent Networks Through Edge and Cloud Integration The transition to a unified and virtualised broadband platform brings further benefits, such as integration with edge computing and cloud-native management and operational tools. Artificial intelligence and machine learning enhance real-time monitoring, allowing networks to self-adjust to traffic variations or address emerging issues before they affect end users. Predictive analytics support proactive maintenance, reducing the likelihood of outages and limiting operational interruptions. Centralised web-based management tools facilitate oversight of both DOCSIS and fibre assets. Operators can analyse network health, adjust configurations and implement changes from a single interface. This consolidation streamlines operations and reduces the need for specialised training or multiple systems. Ultimately, AI-based monitoring and centralised management tools enable operators to maintain high-quality subscriber experiences. This leads to improved subscriber satisfaction and reduced churn. Efficient and Sustainable Network Transformation A Unified DOCSIS 4.0 approach emphasises incremental upgrades that leverage existing infrastructure, reducing both capital and operational costs. By adopting a software-defined architecture,
the need for frequent hardware replacements is minimised. Resource optimisation translates to decreased demands for space, power and cooling in network facilities. From an environmental perspective, fewer hardware changes and energy-efficient components help reduce electronic waste and the carbon footprint of ongoing operations. Virtualised network elements allow for faster deployment cycles, enabling upgrades to roll out over weeks instead of months and supporting business goals with greater agility. Focus on Low Latency to Provide Low Lag Services for Optimal Subscriber Experience The capabilities of advanced cloud-native infrastructure allow operators to build on the introduction of Low Latency DOCSIS (LLD) capabilities to truly provide end-to- end network connectivity with techniques such as L4S (Low Latency, Low Loss, Scalable Throughput). L4S allows for packet marking within subscriber applications to ensure priority for low-latency data, thereby enabling premium quality of experience. This is done by ensuring that data packets are marked for low-latency treatment not just between the cable modem and vCMTS (as LLD allows). But this treatment extends from
Pathways to Practical Implementation
The process of modernising broadband networks involves several practical steps. Operators have the option of deploying distributed access architecture (DAA) nodes that house one or multiple Remote- PHY devices or adapting existing DOCSIS nodes using retrofit solutions. Ensuring Remote-PHY devices can support both FDX and FDD is essential for a unified approach, providing operators with maximum flexibility. Transitioning to virtualised broadband platforms supports more scalable network management. Maintaining backward compatibility with prior DOCSIS versions protects previous investments and allows for smoother operational transitions. Many operators benefit from phased deployment strategies, prioritising high-traffic areas and refining configurations as new segments come online.
