Multi-Layer SDN Orchestrator for Network Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software defined networks (SDNs) lack multi-layer orchestration capabilities, leading to inefficient resource utilization and high energy consumption, as orchestrators typically operate on a single layer and do not automate decisions across all network resources.
Innovation Solution
A method and system for multi-layer orchestration in SDNs, where an orchestrator receives orchestration-related data, determines configuration information based on protocol layer capabilities, and provides optimized configuration to network resources across multiple layers to automate connectivity and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-layer orchestration is used, then device complexity is reduced, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent segments the network orchestration into multiple protocol layers (Layer 1, Layer 2, Layer 3, etc.), with each layer having its own orchestrator that handles specific protocol-level resources. This segmentation allows each orchestrator to focus on optimizing resources at its specific layer while collectively achieving comprehensive multi-layer resource optimization, thus resolving the contradiction between system complexity and resource utilization efficiency.
2Extent of automation
If manual configuration methods are used, then automation extent is reduced, but implementation reliability is improved
Solution Approach 1:
The patent implements feedback mechanisms where each layer orchestrator monitors the state of network resources at its layer and automatically adjusts configurations based on real-time conditions. This automated feedback loop ensures reliable resource allocation and connectivity management while maintaining high automation levels, resolving the contradiction between automation extent and implementation reliability.
3Productivity
If comprehensive resource orchestration is implemented, then productivity is improved, but use of energy deteriorates
Solution Approach 1:
The patent implements partial orchestration by dividing the network into multiple protocol layers, where each layer orchestrator only manages resources at its specific layer rather than orchestrating all network resources comprehensively. This partial action approach maintains adequate orchestration capability for each layer while significantly reducing overall energy consumption compared to a single comprehensive orchestrator, thus resolving the contradiction between productivity and energy usage.

AI summary
Methods, systems, and computer readable media for multi-layer orchestration in software defined networks (SDNs) are disclosed. In one example, the method includes receiving orchestration related data for implementing a network service using the network resources within the SDN, determining configuration information for the network resources based on the orchestration related data and protocol layer capability of the network resources, wherein determining the configuration information includes identifying the network resources having the protocol layer capability to provide network services, and providing the configuration information to the network resources.
