Virtual Service Time Domain Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient synchronization architectures in access networks lead to higher resource consumption and scalability issues as the number of virtual services and remote nodes increases, requiring additional resources for external master clocks and impeding system scalability.
Innovation Solution
Implementing individual time domains for remote nodes and virtual services, where virtual services synchronize to the clock of the remote node by maintaining a time differential based on their own server clock, reducing reliance on external master clocks and facilitating scaling.

Engineering Contradiction Analysis
1Measurement precision
If external master clocks are used for synchronization in access networks, then synchronization accuracy is improved, but resource consumption increases and scalability is impeded
Solution Approach 1:
The patent divides the centralized synchronization architecture into distributed time domains. Each virtual service maintains its own time domain with a local clock, independent from external master clocks. This segmentation allows each component to synchronize locally without requiring resources from a centralized master clock system, thereby reducing overall resource consumption while maintaining synchronization accuracy.
Solution Approach 2:
The virtual services perform self-synchronization by maintaining their own time domains and clocks. Each virtual service independently manages its time domain and synchronizes with remote nodes without requiring external master clock services. This self-service approach eliminates the need for resource-intensive external master clocks while preserving synchronization functionality.
2Reliability
If external master clocks are used for synchronization, then synchronization reliability is improved, but system scalability worsens
Solution Approach 1:
By segmenting the synchronization architecture into distributed time domains, the system can scale by adding more virtual services and remote nodes without affecting the master clock infrastructure. Each virtual service operates independently with its own time domain, allowing linear scalability while maintaining reliable synchronization through local clock management.
Solution Approach 2:
The self-service synchronization model enables the system to scale dynamically as virtual services are added or removed. Each virtual service independently manages its time domain, so the system can accommodate varying numbers of services without requiring changes to external master clock infrastructure, thereby improving scalability while maintaining reliability.
3Ease of operation
If centralized synchronization architecture is used, then synchronization control is improved, but device complexity increases
Solution Approach 1:
The patent segments the centralized control architecture into distributed time domain management. Each virtual service has its own time domain and clock, eliminating the need for complex centralized control mechanisms. This segmentation simplifies the overall architecture by removing external master clock components while maintaining effective synchronization control through local time domain management.
