Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of centralized control over network devices with multiple WAN interfaces leads to inefficiencies in managing and optimizing network resources, making it difficult to monitor performance, identify bottlenecks, and utilize bandwidth effectively.
Innovation Solution
A primary network device manages and controls secondary network devices by establishing virtual connections and data tunnels, allowing it to coordinate the use of WAN interfaces for data transmission and configuration, using bijective relationships between WAN interfaces and data tunnels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If separate management of network devices is used, then device complexity is reduced, but network performance and resource utilization deteriorate
Solution Approach 1:
The patent merges multiple network devices into a unified managed system where a primary network device coordinates secondary network devices. This consolidation allows centralized control of WAN interfaces while maintaining individual device functionality, thereby improving resource utilization without excessively increasing management complexity.
Solution Approach 2:
The primary network device performs multiple functions including managing secondary devices, coordinating WAN interfaces, and optimizing network resources. This multi-functionality allows a single device to handle diverse network management tasks, improving overall system efficiency while avoiding the need for multiple specialized management devices.
2Productivity
If centralized control is implemented, then network performance improves, but device complexity increases
Solution Approach 1:
The patent segments network management functions between primary and secondary network devices. The primary device handles centralized coordination and control, while secondary devices focus on executing specific WAN interface operations. This segmentation allows centralized control to improve performance without concentrating all complexity in a single device.
Solution Approach 2:
The primary network device acts as an intermediary between multiple secondary network devices and the central management system. It translates high-level management policies into specific device operations, thereby implementing centralized control while shielding individual devices from excessive complexity.
3Adaptability or versatility
If hardware replacement is performed, then network functionality improves, but cost increases
Solution Approach 1:
Instead of replacing physical hardware, the patent creates a virtualized management structure where a primary network device controls and coordinates secondary network devices. This virtual copying of management functionality allows enhanced network capabilities without the cost of purchasing and deploying entirely new hardware infrastructure.
Solution Approach 2:
The primary network device provides multi-functional capabilities including device management, WAN interface coordination, and network optimization. This consolidates the functionality that would otherwise require multiple specialized hardware devices, reducing overall hardware costs while maintaining versatile network capabilities.
Data Source
AI summary
This present invention discloses methods and systems for transmitting data packets over a wide area network (WAN) through secondary network devices connected to a primary network device. The primary network device first takes control of the secondary network devices' network settings. Then, it creates two separate connections: one for managing the secondary network devices (using management interfaces) and another for transmitting data (using transmission interfaces). The data packets transmit through the WAN connection on the secondary network devices using a special tunnel created within the data connection, following rules set by a policy.
