Network System Intra-Network Loopback Bypasses ISP Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication speed instability occurs when a spoke base communicates with an external device via the Internet due to congestion in the network termination device in existing network systems.
Innovation Solution
A network system that includes a hub base with a first network device and a spoke base without a hub function, where communication between a computer at the spoke base and an external device is performed through intra-network loopback communication without an internet service provider, and the first network device communicates with the external device via an internet service provider, allowing for VPN connections based on address information issued by either the internet service provider or the information communication network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spoke base communicates with the external device via the hub base through the network termination device and ISP, then the communication can be established, but the communication speed becomes unstable due to congestion in the network termination device
Solution Approach 1:
The communication path is segmented into two independent routes: one for intra-network communication (bypassing the congested network termination device) and one for external Internet communication (through the network termination device and ISP). This segmentation allows traffic to be routed differently based on destination, preventing congestion from affecting all communications equally.
Solution Approach 2:
The invention introduces an intermediary routing mechanism that directs traffic through different paths. For spoke-base-to-spoke-base communication, traffic uses intra-network loopback communication bypassing the network termination device. For spoke-base-to-Internet communication, traffic goes through the network termination device and ISP. This intermediary routing resolves the congestion problem by providing alternative paths.
2Device complexity
If the network system uses a single communication path through the network termination device for all traffic, then the network structure is simple, but the communication speed becomes unstable when traffic increases
Solution Approach 1:
The network system dynamically selects communication paths based on traffic type and destination. The routing is not fixed but adapts to different communication scenarios: intra-network traffic uses loopback communication, while external traffic uses ISP routing. This dynamic path selection maintains simplicity in individual paths while providing complexity in overall routing strategy to handle congestion.
3Reliability
If the spoke base uses PPPoE method to connect to the Internet, then authentication is performed, but the communication speed is not stable when traffic increases due to congestion
Solution Approach 1:
The communication path is segmented into two independent routes: one for intra-network communication (bypassing the congested network termination device) and one for external Internet communication (through the network termination device and ISP). This segmentation allows traffic to be routed differently based on destination, preventing congestion from affecting all communications equally.
Solution Approach 2:
The system changes the communication parameter (routing path) based on the destination. For local network destinations, the path parameter is set to bypass the network termination device. For Internet destinations, the path parameter routes through the network termination device and ISP. This parameter change allows the system to maintain fast authentication while avoiding congestion during data transfer.

AI summary
A network system includes: a hub base that includes a first network device with a hub function, the first network device being connected to an information communication network; and a spoke base that includes a second network device without the hub function, the second network device being connected to the information communication network. Communication between a computer provided in the spoke base and an external device connected with the computer via Internet is performed such that intra-network loopback communication is performed between the first network device and the second network device in the information communication network without an internet service provider, and communication is performed between the first network device and the external device via the internet service provider.
