Remote Physical Device Configuration in Distributed Access Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed access architectures face challenges in configuring legacy video networks for video delivery, particularly in identifying connected video services at remote physical devices and scaling across multiple devices, due to the removal of digital to analog conversion from the headend.
Innovation Solution
A system using anchor points and attribute labels to automate the configuration of remote physical devices, allowing a management system to drive both manual and automated configuration changes by defining video configurations for video delivery, aligning anchor points with geographic locations or physical distribution paths and applying labels to represent video characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distributed access architecture removes digital to analog conversion from headend to remote device, then video delivery independence is improved, but configuration complexity of remote physical devices increases
Solution Approach 1:
The system performs preliminary actions by automatically generating remote physical device configurations before deployment. The configuration generation system creates device-specific configurations based on network topology information, video service requirements, and remote device capabilities, eliminating the need for manual configuration after deployment.
Solution Approach 2:
The configuration generation system enables self-service by automatically configuring remote physical devices without manual intervention. The system retrieves network topology data, identifies video services for each remote device, and generates appropriate configurations autonomously, reducing operational complexity.
2Manufacturing precision
If manual configuration is performed for each remote physical device, then configuration accuracy is improved, but deployment time and scalability worsen
Solution Approach 1:
The system uses copying by generating configurations for multiple remote physical devices based on templates and network topology patterns. Instead of manually configuring each device individually, the system creates standardized configuration templates and automatically instantiates them across multiple devices, ensuring consistency while dramatically reducing deployment time.
Solution Approach 2:
The configuration generation system applies parameter changes by dynamically adjusting configuration parameters based on specific network conditions, video service requirements, and remote device capabilities. The system automatically modifies configuration parameters such as frequency allocations, service mappings, and device identifiers to match each deployment scenario while maintaining accuracy.
3Productivity
If automated configuration system is implemented, then deployment efficiency is improved, but system complexity increases
Solution Approach 1:
The configuration generation system achieves universality by designing a multi-functional platform that handles multiple tasks: retrieving network topology information, identifying video services, generating device configurations, and deploying configurations across various remote physical devices. This unified system approach manages complexity through consolidation rather than proliferation of separate tools.

AI summary
In one embodiment, a method receives a network topology of a distributed access architecture and a legacy video network. Video streams include characteristics that are associated with delivery via the legacy video network. The method selects a set of anchor points for a remote physical device in the distributed access architecture where the set of anchor points are associated with a geographic location of the remote physical device. A set of attribute labels are selected for the set of anchor points where the set of attribute labels associated with characteristics of the video streams. The method then generates a definition of video streams based on the anchor points and the attribute labels for a remote physical device configuration and generates the remote physical device configuration for video. The remote physical device configuration is used to provide the video streams to the remote physical device.
