Energy Aware Network Slicing Power SLA Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network slicing technologies do not effectively enforce power Service Level Agreements (SLAs) for individual network slices, leading to inefficient power usage and potential performance issues across network nodes.
Innovation Solution
The implementation of energy-aware network slicing systems that select specific computing platforms and CPUs for energy-efficient operations, assign cores within power constraints, and utilize a power-aware controller and traffic manager to ensure power consumption does not exceed specified thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network slicing is implemented on shared physical infrastructure, then resource utilization and network capacity are improved, but power consumption and energy efficiency become difficult to control
Solution Approach 1:
The patent segments the shared physical infrastructure into multiple isolated network slices, each with dedicated hardware resources (CPU cores, memory, I/O devices). This segmentation allows independent power management for each slice while maintaining overall resource utilization efficiency.
Solution Approach 2:
The patent applies local quality by assigning different power management characteristics to different network slices based on their specific requirements. Each slice can have customized power budgets, performance profiles, and resource allocation strategies tailored to its service level agreement.
2Loss of energy
If power consumption is strictly enforced for each network slice, then energy efficiency is improved, but system complexity and difficulty of management increase
Solution Approach 1:
The patent introduces a network slice manager as an intermediary component that handles power management tasks. This manager abstracts the complexity of power enforcement from individual network operations, providing a centralized interface for power budget allocation and monitoring across all slices.
Solution Approach 2:
The network slice manager performs multiple functions including resource allocation, power monitoring, performance management, and isolation enforcement. This multi-functionality consolidates what would otherwise be separate complex systems into a single manageable component.
3Productivity
If hardware resources are shared among network slices, then resource utilization is improved, but performance isolation and service quality guarantee become difficult to maintain
Solution Approach 1:
The patent physically segments hardware resources (CPU cores, memory, I/O devices) and assigns them to specific network slices. This segmentation ensures that each slice has dedicated resources that cannot be accessed by other slices, providing strong performance isolation while maintaining high overall utilization through efficient resource assignment.
