Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-link VPN systems fail to optimize link selection based on Quality of Service (QoS) parameters and data traffic requirements, leading to inefficient data transmission.
Innovation Solution
An Information Handling System (IHS) with a multi-link VPN link selection engine that monitors network interfaces, identifies QoS parameters, and selects the most suitable link for data transmission based on specific requirements, ensuring efficient data traffic delivery.

Engineering Contradiction Analysis
1Reliability
If conventional multi-link VPN systems use multiple links for redundancy purposes, then system reliability is improved, but data transmission efficiency deteriorates because links are not selected based on QoS parameters and traffic requirements
Solution Approach 1:
The system dynamically selects network links based on real-time QoS parameters and data traffic requirements, transitioning from static redundancy to adaptive link selection. The link selection engine continuously monitors network conditions and adjusts link usage accordingly, making the system both reliable and efficient.
Solution Approach 2:
The system changes the selection criterion from simple availability (binary on/off) to multiple QoS parameters (bandwidth, latency, jitter, packet loss). By evaluating links based on these varying parameters and matching them with traffic requirements, the system achieves both reliability and transmission efficiency.
2Productivity
If multi-link VPN systems monitor and evaluate QoS parameters for each network interface, then data transmission efficiency is improved, but system complexity increases
Solution Approach 1:
The link selection engine serves multiple functions: monitoring QoS parameters, evaluating network interfaces, matching traffic requirements, and selecting optimal links. By consolidating these functions into a single multi-functional component, the system achieves efficiency improvement without proportional increases in overall complexity.
Solution Approach 2:
The system automatically monitors QoS parameters and performs link selection without manual intervention. The link selection engine self-manages the evaluation and decision-making process, reducing operational complexity while maintaining high transmission efficiency.

AI summary
A multi-link VPN link selection system includes a multi-link VPN server device that provides a VPN connection to application server device(s) for a computing device. The computing device monitors each of its network interfaces that each provide a respective link to the VPN connection and, in response, identifies one or more QoS parameters associated with each of those network interfaces. When the computing device receives data traffic from application(s) operating on the computing device, it identifies a network transmission requirement associated with that data traffic, determines one of the network interfaces that is associated with one or more QoS parameters that satisfy the network transmission requirements associated with that data traffic; and transmits that data traffic via that network interface and over the respective link provided by that network interface to the application server device(s) via the VPN connection provided by the multi-link VPN server device.
