Unified Cloud SDN Traffic Slicing and Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional communication networks face limitations in scalability and bandwidth management, leading to packet drops during traffic bursts, which negatively impact user experience and are costly to maintain due to reliance on expensive hardware and multiple infrastructure layers.
Innovation Solution
Implementing a software-defined networking (SDN) system using White Boxes and centralized control to manage traffic across a unified cloud, enabling traffic slicing and buffering, and reducing the need for multiple infrastructure layers, while maintaining quality of service (QoS).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hierarchical network architecture with multiple infrastructure layers is used, then network reliability and service differentiation are improved, but device complexity and operational costs increase
Solution Approach 1:
The patent merges multiple separate network infrastructures (mobile network, broadband network, enterprise network) into a single unified cloud infrastructure. This consolidation reduces the number of separate network layers while maintaining service differentiation through software-based traffic slicing and routing, thereby reducing device complexity while preserving network reliability.
Solution Approach 2:
The unified cloud infrastructure provides multi-functional capability to handle diverse traffic types (mobile, broadband, enterprise) through a single platform. The system uses universal routing and buffering mechanisms that can serve multiple service types simultaneously, eliminating the need for separate specialized infrastructure layers for each service type.
2Productivity
If expensive hardware and multiple infrastructure layers are deployed, then network capacity and service quality are improved, but capital expenses and operational costs increase
Solution Approach 1:
The patent replaces traditional hardware-based network capacity management with software-defined networking mechanisms. Instead of relying on expensive physical infrastructure layers for each service type, the system uses software-based traffic slicing, buffering, and routing to manage network capacity, thereby reducing hardware investment while maintaining or improving network capacity.
Solution Approach 2:
The system dynamically adjusts network parameters such as buffering capacity, routing paths, and traffic shaping policies to optimize network capacity utilization. By changing these parameters dynamically rather than relying on static hardware capacity, the system can provide high network capacity with reduced infrastructure investment.
3Stability of the object's composition
If static network architecture is used, then infrastructure stability is maintained, but adaptability to dynamic computing and storage needs deteriorates
Solution Approach 1:
The patent implements a dynamic network architecture where traffic routing, buffering, and slicing decisions are made in real-time based on current network conditions and service requirements. The unified cloud platform can dynamically adjust its behavior to adapt to changing computing and storage needs while maintaining infrastructure stability through centralized control and coordinated management.
