Ring Communication System Bandwidth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in achieving ultra-wideband and large capacity data transmission while maintaining high efficiency and reliability, particularly in scenarios like GPU data transfer and AI processor communication, due to limitations in signal transmission techniques and increased costs with numerous communication lines.
Innovation Solution
A communication system with a ring-connected configuration where devices monitor data transmission amounts and insert or remove packets from a communication frame based on bandwidth restrictions, ensuring uniform transmission authority and efficient use of bandwidth across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple communication lines are used for high-speed data transmission, then data transmission capacity is improved, but system cost and complexity increase
Solution Approach 1:
The communication system segments data into packets that are transmitted individually through the ring topology, allowing multiple data streams to share a single communication channel without requiring multiple dedicated lines for each device pair
Solution Approach 2:
The single ring-shaped communication channel serves multiple functions by allowing any device to transmit data to any other device in the network, replacing the need for dedicated point-to-point communication lines between each device pair
2Reliability
If bandwidth restriction is applied to ensure fair packet transfer, then transmission fairness is improved, but data transmission speed may be limited
Solution Approach 1:
The system applies periodic bandwidth restrictions by monitoring data transmission amounts over time intervals and comparing them against threshold values, allowing devices to transmit at high speeds when below thresholds while ensuring fair overall distribution
Solution Approach 2:
The bandwidth restriction mechanism dynamically adjusts transmission permissions based on real-time monitoring of data transmission amounts, allowing transmission speeds to vary adaptively rather than being fixed, thus maintaining both fairness and efficiency

AI summary
A communication system includes a controller, a plurality of devices, and a communication channel to which the controller and the plurality of devices are connected in a ring, and over which a communication frame including a plurality of packets is transmitted as differential signals. Each device monitors a data transmission amount per unit time, and is configured to determine whether or not the monitored data transmission amount exceeds a threshold value, and insert data into one of the packets in the communication frame when the monitored data transmission amount is equal to or less than the threshold value.
