Integrated Cloud-Network Switching for Continuous Communication Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems face delays and difficulties in continuous service provision due to the independent optimization of cloud resource and network redundancy configurations, requiring separate switching by cloud and network controllers, which can lead to increased delays and service disruptions.
Innovation Solution
A communication system with an integrated controller that collects and integrates cloud and network information to coordinate simultaneous switching of cloud resources and network paths, minimizing delays by optimizing the switching process based on both cloud and network information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cloud controller and network controller are used for independent optimization, then cloud resource configuration and network configuration can be optimized individually, but switching delays increase and continuous service provision becomes difficult
Solution Approach 1:
The patent combines the cloud controller and network controller into an integrated controller that manages both cloud resources and network paths simultaneously. This unified control mechanism enables coordinated switching of cloud resources and network paths, eliminating the sequential processing delays inherent in separate controller architectures and ensuring continuous service provision during failover events.
2Ease of operation
If separate controllers are used for cloud resources and network, then each controller can independently manage its domain, but coordination between controllers increases complexity and switching time
Solution Approach 1:
The patent merges the cloud controller and network controller into a single integrated controller that manages both cloud resources and network paths. This consolidation eliminates the coordination complexity between separate controllers while maintaining the ability to independently manage cloud and network domains through unified control logic within the integrated controller.
3Reliability
If separate switching of cloud resources and network paths is performed, then each switching operation can be optimized independently, but the overall switching process takes longer and may cause service disruption
Solution Approach 1:
The integrated controller performs preliminary assessment of both cloud resource status and network path status simultaneously before initiating switching operations. This allows the controller to prepare switching instructions for both cloud resources and network paths in advance, enabling coordinated execution that minimizes total switching time and prevents service disruption.
Solution Approach 2:
The patent combines the switching operations of cloud resources and network paths into a single coordinated process managed by the integrated controller. This unified switching mechanism executes both switching operations simultaneously or in optimized sequence, eliminating the cumulative delays of separate switching operations and ensuring service continuity.
