NaaS Device Automates SDN Service Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network management processes for configuring services in software-defined networking (SDN) are complex and inefficient, particularly when dealing with multiple types of upper-layer applications and enhanced functions, as they require manual selection and configuration of physical network devices, reducing work efficiency.
Innovation Solution
A method and apparatus using a Network as a Service (NaaS) device to automatically configure services by obtaining contracts with identifier information and communication requirements, selecting appropriate network device groups, generating forwarding rules, and sending them to a controller, thereby simplifying the configuration process and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection and configuration of physical network devices is performed, then service configuration can be completed, but work efficiency is reduced and complexity increases
Solution Approach 1:
The system enables self-service automation where the NaaS device automatically performs service configuration without manual intervention. The automated configuration system selects appropriate physical network devices and configures services based on user requirements, eliminating the need for manual device selection and configuration while improving work efficiency
Solution Approach 2:
The patent introduces a NaaS device as an intermediary between users and physical network devices. This intermediary automatically translates user service requirements into device configuration parameters, managing the complexity of device selection and configuration processes while improving ease of operation and productivity
2Adaptability or versatility
If more types of upper-layer applications and enhanced functions are added, then service functionality is improved, but service configuration complexity increases and work efficiency is reduced
Solution Approach 1:
The NaaS device serves as an intelligent intermediary that manages the complexity of configuring multiple application types and enhanced functions. It automatically maps diverse service requirements to appropriate physical network device capabilities, maintaining adaptability while reducing configuration complexity through automated device selection and parameter configuration
Solution Approach 2:
The system implements a universal configuration approach where the NaaS device handles multiple types of upper-layer applications and enhanced functions through a unified automated process. This multi-functional capability allows the system to manage diverse service requirements without proportionally increasing configuration complexity
