Solution Overview
Problem
Current systems face challenges in managing bandwidth reservations effectively between LAN and WAN communication networks, particularly in residential gateways, where the rapid increase in LAN capacities outpaces WAN capacities, leading to inefficient throughput and latency constraints, and existing solutions consume excessive processing resources.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth reservation is increased to ensure flow and latency constraints for critical data flows, then service quality is improved, but processing resources are consumed excessively
Solution Approach 1:
The patent implements dynamic bandwidth reservation that adapts to actual network conditions. The system continuously monitors effective throughput of critical data flows and adjusts bandwidth reservations in real-time, transitioning from static to dynamic resource allocation. This resolves the contradiction by making the system flexible enough to maintain service quality while optimizing processing resource usage based on actual needs.
Solution Approach 2:
The patent changes the parameter of bandwidth reservation from fixed to variable based on measured effective throughput. By monitoring actual throughput values and adjusting reservation parameters dynamically, the system maintains flow and latency constraints while reducing unnecessary processing overhead associated with static over-provisioning.
2Productivity
If bandwidth reservation is optimized to match effective throughput, then processing resource consumption is reduced, but service quality may deteriorate
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors effective throughput of critical data flows and uses this information to adjust bandwidth reservations. The system measures actual throughput, compares it with current reservations, and dynamically adjusts reservations to match actual needs. This feedback loop ensures service quality is maintained while optimizing processing resource efficiency.
Solution Approach 2:
The system performs self-adjustment of bandwidth reservations based on its own monitoring of effective throughput. By autonomously adapting reservations to actual traffic patterns without external intervention, the system maintains service quality while improving processing resource efficiency through automated optimization.
3Device complexity
If static bandwidth reservation is used to simplify management, then device complexity is reduced, but network efficiency decreases due to unnecessary reservations
Solution Approach 1:
The patent transitions from static to dynamic bandwidth reservation management. The system automatically monitors effective throughput and adjusts reservations dynamically, eliminating the need for complex manual configuration while improving network efficiency by matching reservations to actual traffic patterns.
4Speed
If bandwidth reservation is increased to accommodate LAN capacity growth, then network capacity is improved, but WAN side efficiency decreases due to mismatched reservations
Solution Approach 1:
The patent implements dynamic bandwidth reservation that adapts to the asymmetry between LAN and WAN capacity evolution. By continuously monitoring effective throughput on the WAN side and adjusting reservations accordingly, the system accommodates LAN capacity growth while maintaining efficient WAN utilization, resolving the mismatch between reservation policies and actual network conditions.

AI summary
The invention relates to a device for interconnecting first and second networks, through which streams of critical data pass, wherein said data streams require that bandwidth be reserved in order to comply with speed and latency constraints, the interconnection device performing the following steps for each stream of critical data: measuring (409) an actual speed of said stream of critical data; verifying (410) whether said actual measured speed is greater than the sum of a previously reserved bandwidth and a tolerance bandwidth; verifying (410) whether said actual measured speed is lower than the previously reserved bandwidth, from which the sum of a margin bandwidth and a tolerance bandwidth is subtracted; and if the verification is positive, adjusting (411) the reserved bandwidth for said stream of critical data to a value equal to the sum of the actual measured speed for said stream of critical data and the margin bandwidth.
