Resiliency Policy Framework for High-Resilience Network Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-resiliency networks, particularly those using 5G Ultra-Reliable and Low-Latency Communication (URLLC) and Time Sensitive Network (TSN) services, face challenges in deploying wireless technologies that meet stringent availability and scheduling requirements, and determining the best technology mix for specific use cases, such as manufacturing and autonomous vehicle control environments.
Innovation Solution
The implementation of a system that calculates intended resiliency for each access network based on resiliency characteristics, determines zone policies for connectivity zones, and communicates network and client access resiliency policies to ensure high-resiliency network deployments across wireless and cabled networks, using a combination of 3GPP, Wi-Fi, and other access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless technologies (3GPP, Wi-Fi) are deployed to provide high-resiliency services, then network coverage and accessibility are improved, but ensuring compliance with stringent availability and scheduling requirements becomes more difficult
Solution Approach 1:
The patent introduces a network access resiliency policy system that acts as an intermediary between wireless access networks and high-resiliency services. This policy framework mediates by calculating intended resiliency for each access network, determining zone policies for connectivity zones, and enforcing client access resiliency policies, thereby ensuring availability compliance while maintaining wireless deployment flexibility
Solution Approach 2:
The system dynamically adjusts resiliency parameters including intended resiliency calculations, zone policy configurations, and client access policies based on network conditions and service requirements. By changing these parameters adaptively, the system maintains reliability compliance across diverse wireless technologies without sacrificing coverage
2Reliability
If multiple access network technologies are combined to meet service criteria, then resiliency and availability are improved, but network complexity increases
Solution Approach 1:
The patent segments the network into connectivity zones with specific resiliency requirements and applies differentiated policies to each zone. By dividing the network management into zone-level and client-level policies, the system handles multiple access technologies through modular policy enforcement rather than monolithic complexity
Solution Approach 2:
The resiliency policy framework serves multiple functions simultaneously: it calculates intended resiliency for diverse access networks, determines zone policies for different connectivity zones, enforces client access policies, and provides assurance for high-resiliency services. This universal policy system manages complexity by providing a single multi-functional mechanism rather than separate systems for each function
3Manufacturing precision
If stringent resiliency metrics are enforced for URLLC and TSN services, then service quality is improved, but network deployment flexibility is reduced
Solution Approach 1:
The system implements dynamic resiliency policy enforcement that adapts to different deployment scenarios. By calculating intended resiliency based on actual network conditions and adjusting zone policies and client access policies dynamically, the system maintains scheduling accuracy for URLLC and TSN services while preserving deployment flexibility across varying environments
