Unified NFV Resource Model for Mixed VM and Container VNFs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of NFV infrastructure systems increases with the addition of mixed VM and container infrastructures due to differing resource models and the need for separate communication models, making it difficult to synchronize the MANO system and manage resources efficiently.
Innovation Solution
An NFV infrastructure system using a master node with a unified MANO system and worker nodes with extended container infrastructure, employing a unified resource model based on the NFV-SOL standard to distribute and manage VNFs across VM and container-based infrastructures, eliminating the need for separate communication modules and resource model conversions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple VM and container infrastructures are mixed and used, then resource flexibility and adaptability are improved, but system complexity and difficulty of synchronization increase
Solution Approach 1:
The patent implements a unified resource model that serves multiple infrastructure types (VM and container infrastructures) through a single interface. The MANO system uses a common resource model format that can represent both virtual machine resources and container resources, eliminating the need for separate communication models and reducing system complexity while maintaining support for diverse infrastructure types.
2Adaptability or versatility
If separate communication models are used for each infrastructure, then infrastructure-specific requirements are met, but the complexity of the whole NFV infrastructure system increases
Solution Approach 1:
The patent employs a universal resource model format that can represent resources from different infrastructure types (VM and container) using the same structure. This unified model allows the MANO system to communicate with multiple infrastructure types without requiring separate communication models, thereby reducing overall system complexity while maintaining infrastructure-specific capabilities.
3Adaptability or versatility
If resource model conversion is performed by the MANO system, then compatibility between different infrastructures is achieved, but synchronization difficulty and management overhead increase
Solution Approach 1:
The patent merges the resource model representation into a single unified format that can directly represent both VM and container resources. By combining the previously separate resource models into one unified model, the system eliminates the need for complex conversion processes and reduces management overhead, as administrators can manage all resources through a single consistent interface.

AI summary
An NFV infrastructure system based on a container infrastructure includes a master node configured to distribute and manage a virtual network function (VNF) which is an individual network function according to a request by an administrator; and a worker node of an extended container infrastructure structure which allocates the distributed VNF to a VM based infrastructure or a container based infrastructure, wherein a resource model between the master node and the worker node is a resource model which is the same as a resource model according to the request by the administrator.
