Solution Overview
Problem
Cable hubs face challenges in sustainable scaling and operational efficiency due to hardware-based approaches, which are labor-intensive and costly, struggling to meet growing consumer demands and compete with fiber-to-the-home services.
Innovation Solution
The implementation of a virtual cable hub using software-based solutions, such as virtualization, containerization, and cloud technologies, allows for the separation of software from hardware, enabling scalable, agile, and efficient deployment of services on commercial off-the-shelf x86 platforms, reducing physical space and power consumption while improving service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware-based approaches are used in cable hubs, then device stability and reliability are maintained, but scalability and operational efficiency deteriorate due to labor-intensive operations and high costs
Solution Approach 1:
The patent replaces hardware-based mechanical systems with software-based virtualization technologies. Specifically, it implements virtual cable hubs using software-defined networking (SDN) and network virtualization, where virtual network functions (VNFs) replace traditional hardware appliances. This substitution enables automated service deployment, dynamic resource allocation, and reduced manual configuration, thereby improving operational efficiency while maintaining system reliability through virtualized infrastructure management.
Solution Approach 2:
The patent changes the fundamental parameter of system implementation from hardware-centric to software-centric. By transitioning from physical hardware appliances to virtualized software instances running on commercial off-the-shelf (COTS) servers, the system achieves improved scalability and operational efficiency. The virtualization layer abstracts the underlying hardware, allowing dynamic provisioning and management of network services without physical hardware changes.
2Reliability
If hardware-based approaches are used in cable hubs, then device stability is maintained, but adaptability and service deployment speed deteriorate
Solution Approach 1:
The patent replaces hardware-based systems with software-defined networking and virtualization technologies. Virtual cable hubs implemented through software allow rapid service deployment and easy adaptation to new services without requiring physical hardware changes. The virtualized architecture enables dynamic service provisioning, automated configuration, and flexible resource allocation, significantly improving adaptability while maintaining stability through virtualized infrastructure management.
Solution Approach 2:
The patent implements a universal virtualized platform that can host multiple network services and functions on common hardware infrastructure. The virtual cable hub architecture allows a single physical platform to provide multiple services (DSL, cable, fiber, wireless access) through software instances, enabling rapid adaptation to different service requirements without dedicated hardware for each service type.
3Productivity
If virtualization and software-based solutions are implemented, then scalability and operational efficiency are improved, but system complexity increases
Solution Approach 1:
The patent introduces a virtualization layer as an intermediary between the physical hardware infrastructure and the network services. This virtualization layer abstracts the complex hardware management tasks, providing simplified service provisioning and management interfaces. The intermediary layer handles resource allocation, service deployment, and configuration automation, thereby improving operational efficiency while managing system complexity through abstraction.
Solution Approach 2:
The patent implements automated service deployment and management capabilities within the virtualized cable hub architecture. The system includes self-provisioning features, automated configuration, and dynamic resource allocation that reduce manual intervention requirements. Service instances can be automatically deployed, configured, and managed through software automation, improving operational efficiency while the self-service capabilities help manage complexity by eliminating manual configuration tasks.
Data Source
AI summary
A multi-tenant application that provides high speed data services to one or more subscriber devices. High speed data services may include one or more of Dynamic Host Configuration Protocol (DHCP) services, software upgrade services, and Profile Management Application (PMA) services. The multi-tenant application comprises one or more first servers that each perform packet switching and routing and one or more second servers that each perform FCAPS functions for the one or more subscriber devices. FCAPS functions comprise fault operations, configuration operations, accounting operations, performance operations, and security operations. Second servers may be implemented entirely within an application-specific logical host composed of one or more application containers and may optionally each further perform network functions and user plane functions for the one or more subscriber devices. The one or more second servers may optionally each further perform OLT control functions and OLT MAC/PHY functions for the one or more subscriber devices.
