Ring Network Node Embedding Interrupt Packets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems using ring networks, data with high priority cannot be transmitted promptly without compromising transmission efficiency, as existing methods either delay low-priority data packets or increase the number of data packets, leading to increased processing loads and reduced efficiency.
Innovation Solution
A communication system where each node includes a software-operated data generator for generating ordinary and interrupt transmission data, with an output switching unit that embeds interrupt packets into ordinary packets, ensuring interrupt packets are output preferentially and processed immediately, without reducing the size of ordinary packets, thus maintaining transmission efficiency.

Engineering Contradiction Analysis
1Speed
If data is divided into smaller data segments to form data packets with smaller size for priority transmission, then high-priority data can be transmitted more promptly, but the number of data packets increases, leading to increased header and trailer data and reduced transmission efficiency
Solution Approach 1:
The patent embeds interrupt packets (high-priority data packets) within ordinary packets (low-priority data packets) that are already being transmitted. This nesting approach allows high-priority data to be transmitted without waiting for separate packet transmission, while utilizing the existing packet structure to avoid increasing the total number of packets and their associated overhead.
2Stability of the object's composition
If the transmission of data packet with low priority is started, then transmission continuity is maintained, but it is necessary to wait for completion of low-priority packet transmission before starting high-priority data transmission
Solution Approach 1:
The patent prepares ordinary packets for transmission in advance and embeds interrupt packets within them before transmission begins. This preliminary embedding of high-priority data within the structure of low-priority packets allows both transmission types to proceed simultaneously without waiting for completion of one before starting the other.
3Ease of operation
If data packets are sorted and processed at each node, then proper transmission order is maintained, but processing load for sorting and processing incoming data packets increases
Solution Approach 1:
The patent combines interrupt packet transmission with ordinary packet transmission by embedding the interrupt packet within the ordinary packet structure. This merging eliminates the need for separate transmission channels and reduces the processing load at each node, as nodes only need to handle a single packet stream rather than separately managing and sorting multiple priority queues.

AI summary
In a communication system having multiple nodes communicably connected via a ring network, at least two of the nodes each includes: a packet distributor that receives an ordinary packet and an interrupt packet from another node and distributes the received packets; and an output switching unit that outputs the ordinary packet and the interrupt packet that are not addressed to the own node such that the interrupt packet is output more preferentially than the ordinary packet. When the output switching unit receives the interrupt packet while outputting the ordinary packet, the output switching unit outputs the interrupt packet by embedding it into the ordinary packet that is being output at a position between the header and trailer of the ordinary packet. When the ordinary packet transmitted from the other node contains an interrupt packet embedded therein, the packet distributor extracts the interrupt packet and distributes the extracted interrupt packet.
