Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scalable network interface systems face challenges in achieving isolation at scale, as current solutions require manual setup by network engineers and are not feasible for dynamically creating one-to-one port networks.
Innovation Solution
A scalable network interface system that dynamically creates one-to-one port networks using a VPN credentialing module and network address translation (NAT), enabling secure and isolated communication paths between networks while maintaining scalability.

Engineering Contradiction Analysis
1Extent of automation
If manual setup by network engineers is used for scalable network interface systems, then network security and isolation are maintained, but scalability and automation are severely limited
Solution Approach 1:
The system enables self-service automation through the credentialing module that automatically generates VPN credentials and establishes network interfaces without manual network engineer intervention. The credentialing module autonomously manages the creation, distribution, and revocation of access credentials, allowing the system to serve itself rather than requiring external manual configuration for each network interface.
Solution Approach 2:
The credentialing module acts as an intermediary between the network access request and the actual network interface creation. It mediates the authentication process by verifying credentials, generating VPN access information, and coordinating with network devices to establish isolated communication paths, thereby automating what previously required manual network engineer intervention.
2Productivity
If one-to-one port networks are created dynamically at scale, then network accessibility and scalability are improved, but maintaining isolation and security becomes more difficult
Solution Approach 1:
The system segments network communication into isolated one-to-one port networks, where each network interface operates in its own dedicated communication channel. This segmentation ensures that even as the number of interfaces scales dynamically, each interface maintains strict isolation from others through individual VPN tunnels, preventing cross-contamination and maintaining security boundaries at scale.
Solution Approach 2:
Each network interface is configured with local quality properties specific to its authentication credentials and access requirements. The credentialing module ensures that each interface has its own unique VPN credentials, routing rules, and security parameters, allowing rapid scaling while maintaining customized isolation and security characteristics for each individual interface.
3Ease of operation
If VPN credentials are automatically generated and distributed, then ease of operation is improved, but security risks from credential management increase
Solution Approach 1:
The credentialing module dynamically changes credential parameters including generating unique VPN usernames, passwords, and certificates for each authentication event. It modifies security parameters such as credential expiration times, access permissions, and encryption keys based on authentication results, thereby maintaining ease of automatic credential distribution while mitigating security risks through parameter variability and revocability.

AI summary
A computer readable medium having non-transitory memory for storing machine instructions that are to be executed by a computer. The machine instructions when executed by the computer implement the following function: establishing a network interface communication path between a first router on a first network and a second router on a second network. The first network including first and second network devices is in communication with the first router. A further function is establishing a first network interface between the second router and the first network device through the network interface communication path and a second network interface between the second router and the second network device through the network interface communication path. A further function includes permitting access to the first and second network devices through the first and second network interfaces, respectively, by a user application. The network interfaces may be virtual private networks (VPNs).
