CMTS Software Packaging for Dependency-Safe Driver Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of software drivers and programs in Cable Modem Termination Systems (CMTS) is often incomplete, leading to service outages due to incompatibilities, incorrect ordering, and missing dependencies, which affects the operation of remote physical devices in CATV networks.
Innovation Solution
A packaging system generates an archive file that includes software and hardware drivers, specifying extraction and deployment dependencies, ensuring compatibility and proper installation order, using encryption and compression to manage software updates and downgrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If software and hardware drivers are manually installed in distributed CMTS systems, then deployment flexibility is improved, but installation completeness and compatibility deteriorate due to incorrect driver selection, missing files, and improper installation order
Solution Approach 1:
The patent applies preliminary action by embedding extraction and deployment dependencies within archive files before distribution. The archive file is pre-configured with all necessary software programs, hardware drivers, and their interdependencies, so that when deployed, the system automatically knows the correct installation order and required files, eliminating manual configuration errors and ensuring complete installation.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of embedded dependencies within archive files that mediate between the distributed CMTS system and the software/hardware components. This intermediary structure automatically manages driver selection, file verification, and installation sequencing, resolving the contradiction between deployment flexibility and installation reliability.
2Productivity
If software updates and hardware changes are frequently deployed in distributed CMTS, then system functionality is improved, but service outages increase due to installation errors
Solution Approach 1:
The patent applies preliminary action by pre-packaging all necessary software and drivers with embedded dependencies before deployment. This ensures that frequent updates and hardware changes can be deployed rapidly without manual intervention, while the pre-configured dependency information prevents installation errors that would cause service outages, thus maintaining both high productivity and service continuity.
3Adaptability or versatility
If multiple software programs and drivers are deployed in distributed CMTS, then system capabilities are improved, but compatibility issues increase due to version conflicts and incorrect locations
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of embedded dependencies within archive files that automatically manage compatibility between multiple software programs and drivers. The dependency information specifies correct versions and installation locations, eliminating version conflicts and placement errors even as system capabilities expand through frequent deployments.
