VNF Instantiation Across CaaS Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current standards and solutions are not mature enough to support the deployment and management of multi-container service sites in NFV systems, particularly in scenarios requiring hybrid orchestration of virtual machines and containers, and existing tools like K8S have limitations in managing large numbers of nodes.
Innovation Solution
The proposed method involves a virtualized network function (VNF) instantiation system that obtains deployment information for container service instances, selects appropriate CaaS clusters, and manages resources by applying for additional physical or virtual machine resources when needed, enabling cross-site deployment and management of container services within a MANO system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If container technology is used for VNF deployment, then resource sharing and deployment flexibility are improved, but management complexity increases due to multi-container service site requirements
Solution Approach 1:
The patent introduces a VNF manager as an intermediary component that bridges the gap between the NFV orchestrator and multiple CaaS clusters. The VNF manager receives deployment requests, selects appropriate CaaS clusters based on resource availability and deployment information, and manages container service instances across clusters. This intermediary layer abstracts the complexity of multi-cluster management while preserving the flexibility benefits of container technology.
Solution Approach 2:
The patent segments the management architecture into distinct functional components: NFV orchestrator for high-level service management, VNF manager for container-specific orchestration, and CaaS cluster managers for individual cluster operations. This segmentation allows each component to focus on specific tasks, reducing overall system complexity while enabling flexible container deployment across multiple sites.
2Quantity of substance
If multi-CaaS cluster deployment is implemented, then resource pooling and scalability are improved, but resource coordination and consistency become more difficult
Solution Approach 1:
The patent implements feedback mechanisms where the VNF manager continuously monitors resource availability across multiple CaaS clusters and adjusts deployment decisions accordingly. The system receives resource status information from each cluster, evaluates deployment information against current resource availability, and dynamically selects appropriate clusters. This feedback loop ensures efficient resource pooling while maintaining coordination consistency across distributed clusters.
3Productivity
If container service instances are deployed across multiple CaaS clusters, then system capacity and redundancy are improved, but deployment and management procedures become more complex
Solution Approach 1:
The patent creates a universal deployment framework where the VNF manager handles multiple functions: receiving deployment requests, parsing deployment information, selecting CaaS clusters, managing container service instances, and coordinating across clusters. This multi-functional approach consolidates complex deployment procedures into a single manageable component, enabling system capacity expansion across multiple clusters without proportionally increasing procedural complexity.

AI summary
This application discloses a VNF service instantiation method and apparatus. The method is performed by a network functions virtualization orchestrator NFVO or a virtualized network function manager VNFM. The method includes: receiving a virtualized network function VNF instantiation request message; obtaining deployment information of a container service instance that needs to be invoked for VNF instantiation; determining one or more container as service sites CaaS clusters based on the deployment information of the container service instance, and sending a container service instance creation request to a container as service manager CaaS manager in each of the one or more CaaS clusters; and receiving a container service instance creation success message from the CaaS manager. According to the foregoing solution, problems of cross-site deployment and management of a container service in an NFV scenario are resolved.
