VNF Scaling Conflict Resolution via EMS Control Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies face conflicts in controlling the scaling of virtualized network functions (VNFs) due to the simultaneous operation of automatic scaling function modules at different levels, leading to ineffective management.
Innovation Solution
A method and device for transmitting management instructions from the Element Management System (EMS) or Network Management System (NMS) to the Virtualized Network Function Manager (VNFM) or VNF instance, allowing direct management of the automatic scaling function, thereby avoiding conflicts and ensuring proper scaling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automatic scaling function modules are deployed at multiple levels (VNF, VNFM, EMS, NMS), then the system provides flexibility and multiple management perspectives, but conflicts occur in controlling scaling of the VNF
Solution Approach 1:
The patent segments the scaling control authority by introducing a configuration parameter that specifies which management level (VNF, VNFM, EMS, or NMS) has the authority to control scaling. This segmentation resolves the conflict by ensuring that only one level can initiate scaling operations at a time, while maintaining the ability to deploy scaling function modules at multiple levels for different management needs.
2Productivity
If multiple automatic scaling function modules operate simultaneously at different levels, then comprehensive monitoring and control capabilities are achieved, but conflicting scaling operations occur
Solution Approach 1:
The patent introduces an intermediary configuration parameter that mediates between multiple scaling function modules operating at different levels. This parameter acts as a coordination mechanism that prevents conflicting scaling operations by ensuring that scaling control is assigned to a single authoritative level, while allowing other levels to maintain monitoring and management capabilities.
3Speed
If automatic scaling is enabled at the VNF level, then rapid local response to performance changes is achieved, but conflicts arise with higher-level management control
Solution Approach 1:
The patent applies dynamics by making the scaling control authority configurable rather than fixed. The configuration parameter can be dynamically adjusted to assign scaling control to different levels (VNF, VNFM, EMS, or NMS) based on operational needs, allowing the system to switch between rapid local response and centralized control as required.

AI summary
A method and device for transmitting a management instruction and managing an automatic scaling function of a VNF is provided. The method for transmitting a management instruction includes: determining by an EMS that an automatic scaling function of the VNF on a VNFM is required to be managed, and transmitting a first management instruction to the VNFM by the EMS, where the first management instruction is used for instructing the VNFM to manage the automatic scaling function of the VNF on the VNFM; or, determining by the EMS that the automatic scaling function of the VNF on a VNF instance is required to be managed, and transmitting a second management instruction to the VNFM or the VNF by the EMS, where the second management instruction is used for instructing the VNFM or the VNF instance to manage the automatic scaling function of the VNF on the VNF instance. A problem of a conflict in controlling scaling of the VNF is solved.
