Solution Overview

Problem

Current bandwidth management systems in networks are inefficient due to static configuration of network devices, leading to suboptimal utilization of bandwidth and potential congestion, as they fail to dynamically adjust to real-time traffic variations without manual administrator intervention.

Innovation Solution

Grouping multiple network devices into a single set allows for dynamic bandwidth management, where each device can adjust its bandwidth based on real-time traffic conditions, with a designated set master managing the distribution and updating peer tables and traffic status to optimize bandwidth allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If bandwidth management is configured statically on individual network devices, then device configuration is simple and stable, but network performance deteriorates due to inability to adapt to real-time traffic variations

Engineering Contradiction:

Improvebandwidth adaptation to traffic variationsVSAvoidbandwidth management configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent groups multiple network devices into a single bandwidth management set, merging their bandwidth control functions. A set master device manages the collective bandwidth allocation for all devices in the set, allowing dynamic adaptation to traffic variations while maintaining simplified individual device configurations. This resolves the contradiction by combining multiple devices to achieve adaptability without increasing individual device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The set master device acts as an intermediary that receives traffic status information from all devices in the set, calculates optimal bandwidth allocations, and distributes updated bandwidth assignments. This intermediary approach enables centralized adaptive bandwidth management while keeping individual network devices simple and stable, resolving the contradiction between adaptability and device complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If manual administrator intervention is used for bandwidth configuration, then configuration precision is high, but time consumption increases due to frequent manual adjustments

Engineering Contradiction:

Improvebandwidth management efficiencyVSAvoidmanual configuration time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The bandwidth management system performs self-service by automatically monitoring traffic status on each network device, calculating optimal bandwidth allocations, and updating configurations without administrator intervention. The set master device continuously adjusts bandwidth assignments based on real-time traffic conditions, eliminating the need for manual reconfiguration and significantly improving management efficiency while reducing time loss.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback loops where each network device reports its traffic status to the set master, which then adjusts bandwidth allocations based on this feedback. This automated feedback mechanism enables the system to adapt to changing traffic conditions in real-time without requiring manual administrator input, resolving the contradiction between management efficiency and time consumption.

Inventive Principle:

Principle #23Feedback

3Productivity

If bandwidth is allocated statically to network devices, then allocation stability is maintained, but network congestion occurs due to suboptimal utilization during traffic variations

Engineering Contradiction:

Improvebandwidth utilizationVSAvoidbandwidth allocation stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent transforms static bandwidth allocation into a dynamic system where the set master device continuously monitors traffic conditions and adjusts bandwidth assignments in real-time. Each network device's bandwidth allocation changes dynamically based on current network conditions, enabling optimal utilization during traffic variations while maintaining overall system stability through coordinated control. This resolves the contradiction by making bandwidth allocation dynamic rather than static.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system segments the bandwidth management function into two parts: stable group-level policy management by the set master and dynamic individual device allocation. This segmentation allows the overall bandwidth allocation strategy to remain stable while individual device allocations adapt dynamically to traffic conditions, resolving the contradiction between utilization efficiency and allocation stability.

Inventive Principle:

Principle #1Segmentation
