Network Functions Virtualization Orchestration Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of network service orchestration and resource management orchestration functions in network functions virtualization networks is challenging due to their coupled nature, making it difficult to ensure hierarchical resource management and network service planning within the same logic entity, especially in large-scale architectures where resource management granularity is finer than network service orchestration.
Innovation Solution
A network functions virtualization system comprising a network service orchestration (NSO) node, a resource management orchestration (RO) node, a virtualized network function manager (VNFM) node, a virtualized infrastructure manager (VIM) node, and a network functions virtualization infrastructure (NFVI) resource, where the NSO node is connected to the RO node through specific interfaces, allowing for flexible deployment of network service orchestration and resource management orchestration functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If network service orchestration and resource management orchestration functions are coupled in the same NFVO entity, then the system structure is simplified, but deployment flexibility and hierarchical resource management capability deteriorate
Solution Approach 1:
The patent segments the NFVO into two independent functional entities: NSO (Network Service Orchestration) and RO (Resource Management Orchestration). This segmentation allows each entity to be deployed independently with appropriate granularity - NSO can be deployed at a coarser granularity aligned with network service planning, while RO can be deployed at a finer granularity to match hierarchical resource management requirements, thereby resolving the contradiction between system simplicity and deployment flexibility
2Ease of operation
If network service orchestration and resource management orchestration are deployed at the same granularity, then deployment is easier, but hierarchical resource management capability deteriorates
Solution Approach 1:
By separating NSO and RO into independent entities, the patent enables them to operate at different deployment granularities. RO can be deployed at a finer granularity to precisely manage hierarchical resources across multiple VIM nodes, while NSO operates at a coarser granularity suitable for network service orchestration. This resolves the contradiction by allowing each function to operate at its optimal granularity level
3Ease of operation
If NFVO is tightly coupled to OSS for network service orchestration, then service management is streamlined, but resource management independence deteriorates
Solution Approach 1:
The patent segments the orchestration functions by making RO independent from OSS while maintaining NSO's connection to OSS. This allows resource management to operate independently with its own policies and control mechanisms, while service management continues to be streamlined through OSS integration. The segmentation resolves the contradiction by allowing different coupling levels for different functional entities
