Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ring network implementations are limited by static bandwidth assumptions, leading to inefficiencies in bandwidth allocation and congestion management, as they do not dynamically adjust communication rates based on changing network conditions.
Innovation Solution
A communication node with a control module that dynamically adjusts communication rates between adjacent nodes by determining congestion conditions and reallocating bandwidth, allowing for asymmetric link bandwidth ratios and optimizing bandwidth efficiency in real-time.

1Productivity
If traditional ring network implementations use static bandwidth assumptions, then network configuration is simple, but bandwidth allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic bandwidth adjustment by allowing each communication node to independently determine its own communication rate based on local congestion conditions. The control module continuously monitors traffic queues and adjusts transmission rates in real-time, transforming the static bandwidth configuration into a dynamic adaptive system that responds to changing network conditions.
Solution Approach 2:
The invention changes the bandwidth parameter from a fixed value to a variable that can be adjusted at each node. Each node can operate at different communication rates (e.g., 155 Mb/s, 622 Mb/s, 1 Gb/s) depending on its congestion state, allowing the system to optimize bandwidth allocation by changing the rate parameter dynamically rather than using a uniform static configuration.
2Productivity
If traditional ring networks assume equal bandwidth in all directions, then control is simplified, but congestion management capability worsens
Solution Approach 1:
The patent segments the ring network into individual communication nodes, each independently managing its own bandwidth and congestion conditions. Instead of treating the entire ring as a uniform system, each node is segmented to make independent congestion control decisions based on its local traffic queue status, enabling differentiated bandwidth allocation in different directions.
Solution Approach 2:
Each communication node is assigned local quality parameters including its own communication rate and congestion state. The control module at each node monitors local conditions (traffic queue depth, priority levels) and adjusts transmission rates accordingly, allowing different nodes to have different bandwidth characteristics based on their specific local conditions rather than applying uniform control throughout the ring.
3Adaptability or versatility
If communication nodes use fixed communication rates, then device operation is simple, but network adaptability worsens
Solution Approach 1:
The patent implements feedback mechanisms where each communication node continuously monitors its own traffic queue conditions and uses this information to adjust its communication rate. The control module receives feedback about congestion levels and automatically modulates transmission rates, creating a closed-loop system that adapts to changing conditions without requiring complex manual intervention.
Solution Approach 2:
Each communication node is designed to self-regulate its own bandwidth based on local congestion conditions. The control module autonomously determines when to increase or decrease communication rates by monitoring its own traffic queue status, eliminating the need for centralized control or complex coordination between nodes while maintaining network adaptability.
4Productivity
If ring networks allocate bandwidth uniformly, then distribution is simple, but throughput optimization deteriorates
Solution Approach 1:
The patent transforms uniform static bandwidth allocation into dynamic adaptive allocation where each node can adjust its transmission rate based on real-time congestion conditions. This allows the system to dynamically redistribute bandwidth to nodes that need it most, optimizing overall throughput by directing more traffic to less congested paths and nodes.
Solution Approach 2:
The invention changes the bandwidth parameter from a uniform fixed value to variable node-specific rates. By allowing each node to operate at different communication rates based on its congestion state, the system can optimize throughput by changing the rate parameter locally at each node rather than maintaining uniform allocation throughout the entire ring.

AI summary
Dynamic, asymmetric rings and related communication equipment and methods are disclosed. Various features may be implemented to provide any or all of several degrees of freedom for managing resources in a communication network. Communication rates may be optimized on a node-to-node basis or overall on a network level. Different rates may be configured and possibly dynamically adjusted between different nodes, and/or for different directions of traffic transfer. Bandwidth can be dynamically allocated along a string of the communication nodes in a ring or linear topology in some embodiments. Direction of traffic transfer represents an additional possible degree of freedom in a ring topology, in that traffic can be transferred in either direction in a ring, such as the direction of least delay.
