Solution Overview

Problem

Existing bandwidth distributors either use fixed bandwidth limiters or adjust based on historical usage, failing to dynamically optimize bandwidth distribution according to available input bandwidth, leading to excessive limitations on output ports when input bandwidth is available.

Innovation Solution

A bandwidth distributor that adjusts bandwidth limiters based on the relationship between available and used input bandwidth by using a bandwidth controller to compare measured or estimated passing bandwidth to a predetermined value, increasing or decreasing limiter settings accordingly.

Solution Approach 1:

The patent implements a feedback mechanism where the bandwidth controller continuously monitors the relationship between available input bandwidth and used input bandwidth, then dynamically adjusts bandwidth limiter settings accordingly. This closed-loop control system ensures optimal bandwidth distribution by comparing actual bandwidth usage against available capacity and automatically modifying limiter parameters to prevent both excessive limitation and overload conditions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent transitions from static fixed bandwidth limiters to dynamic bandwidth limiters that automatically adjust their settings based on real-time network conditions. The bandwidth controller modifies limiter parameters dynamically by comparing available input bandwidth with used input bandwidth, enabling the system to adapt to changing traffic patterns and maximize bandwidth utilization without manual intervention.

Solution Approach 1:

The patent dynamically changes bandwidth limiter parameters based on the measured relationship between available and used input bandwidth. The bandwidth controller adjusts limiter settings by comparing available bandwidth capacity against actual usage, modifying parameters such as bandwidth allocation ratios and threshold values to maintain network stability while maximizing utilization. This prevents both overload conditions and unnecessary limitations.

Solution Approach 2:

The bandwidth distribution system performs self-adjustment through automatic monitoring and control without external intervention. The bandwidth controller continuously measures bandwidth usage patterns, evaluates the relationship between available and used capacity, and autonomously modifies limiter settings to maintain optimal network performance and stability, enabling the system to self-optimize based on real-time conditions.
