Communication Device Buffer Control for Chunk-Level Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face inefficiencies in data transmission due to the possibility of data loss when storing and discarding packets on a packet-by-packet basis, leading to incomplete data transmission.
Innovation Solution
Implementing a communication device with a packet identification unit that identifies data chunks and a buffer control unit that manages packet storage and discard operations based on these chunks, ensuring that packets are stored and discarded in units of data chunks rather than individual packets, thereby reducing data loss and enhancing transmission efficiency.

Engineering Contradiction Analysis
1Reliability
If packets are stored and discarded on a packet-by-packet basis in the buffer, then the buffer capacity is utilized efficiently, but data loss occurs leading to incomplete data transmission
Solution Approach 1:
The invention segments data into chunks at the upper layer before packetization. Each chunk is assigned a unique identifier, and packets belonging to the same chunk are tracked together. This segmentation allows the system to manage packets in logical groups rather than as individual units, ensuring that all packets required to reconstruct a complete data unit are either all stored or all discarded together, thereby preventing data loss while maintaining buffer efficiency.
2Reliability
If all packets belonging to the same chunk are stored together in the buffer, then data completeness is maintained, but buffer space is consumed more rapidly
Solution Approach 1:
The invention applies local quality by differentiating buffer management strategies based on chunk status. Instead of uniformly storing all packets, the system tracks which chunks are complete and which are still being received. Buffer space is allocated dynamically based on local needs - packets from chunks that are already complete or not yet fully received are discarded, while packets from chunks in progress are stored. This localized approach maintains data completeness for active chunks while optimizing buffer space utilization.
3Ease of operation
If packets are discarded from the buffer individually, then buffer management is simple, but data loss occurs affecting transmission reliability
Solution Approach 1:
The invention implements feedback mechanisms through chunk status tracking. The system continuously monitors which packets have been received and which chunks are complete. This feedback information guides buffer management decisions - when a chunk is determined to be complete or when packets are determined to be unrecoverable, the system feedbacks this information to the buffer control logic, which then discards all packets belonging to that chunk atomically. This feedback-driven approach maintains transmission reliability while keeping buffer management logic manageable through systematic tracking.

AI summary
The communication device has a receiver that receives packets from the first device, a packet identifier that identifies the chunk, which is a data unit in a higher layer, to which said packet belongs, a buffer that stores said packet, and a buffer control unit that reads the packet from the buffer and sends it to the second device as a unit of the chunk. The buffer control unit controls the storing of said packets in said buffer and the discarding of the packets from said buffer, and the transmitter reads the packets from the buffer and transmits them to the second device.
