Multi-Slicing Orchestration for Dynamic Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slicing technologies face challenges in dynamically managing multiple logical network slices on demand, particularly in response to varying service requirements, user types, and network conditions, which limits flexibility and efficiency in delivering diverse services over 5G wireless networks.
Innovation Solution
The implementation of a multi-slicing orchestration system that allows for on-demand access to multiple logical network slices, either sequentially or in parallel, based on service types, quality of service (QoS), subscriber types, and real-time network conditions, using Software Defined Networking (SDN) controllers to dynamically instantiate and manage Virtual Network Functions (VNFs) across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network slicing is implemented to support multiple virtual networks, then service diversity and customization are improved, but device complexity and management overhead increase
Solution Approach 1:
A centralized network slice manager is introduced as an intermediary component that coordinates and manages multiple network slices. This manager handles slice instantiation, resource allocation, and traffic routing decisions, thereby reducing the complexity burden on individual network elements while enabling support for diverse services through multiple virtual networks.
2Productivity
If dynamic resource allocation is implemented to respond to varying network conditions, then service quality and efficiency are improved, but control complexity and processing requirements increase
Solution Approach 1:
The network slice manager implements dynamic resource allocation by continuously monitoring network conditions and adjusting slice configurations in real-time. Traffic flows are dynamically routed between different network slices based on current network state, service requirements, and resource availability, enabling the system to adapt to varying conditions without requiring complex manual control at each network element.
3Reliability
If multiple logical network slices are instantiated to meet varying service requirements, then service quality and user satisfaction are improved, but network resource consumption and overhead increase
Solution Approach 1:
The network slice manager enables multiple network slices to share common underlying network infrastructure and resources. By virtualizing network functions and allowing dynamic resource sharing between slices, the system can maintain high service quality across multiple virtual networks while reducing overall resource consumption through efficient resource utilization and avoiding duplication.
