Adaptive ACK Packet Processing with Dynamic Trigger Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing acknowledgement (ACK) mechanism in TCP packets results in a high ACK sending frequency, leading to low data transmission efficiency, particularly in wireless local area networks, due to inefficient resource utilization and adaptation to diverse data transmission scenarios.
Innovation Solution
Implement a flexible ACK packet processing method that supports multiple ACK types, trigger conditions, and feedback information, allowing for dynamic adjustment of ACK packet generation based on specific network conditions and requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the traditional TCP ACK mechanism is used where each data packet triggers an ACK packet, then the receiver can confirm receipt of each packet, but the ACK sending frequency becomes high and data transmission efficiency decreases
Solution Approach 1:
The patent combines multiple ACK packets into a single aggregated ACK packet that confirms receipt of multiple data packets simultaneously. Instead of sending one ACK per data packet, the receiver accumulates acknowledgments for multiple packets and sends them together, reducing the total number of ACK packets while maintaining reliable confirmation of packet receipt.
Solution Approach 2:
The patent implements periodic ACK sending where the receiver sends ACK packets at predetermined time intervals or after receiving a predetermined number of data packets, rather than immediately after each packet. This periodic approach reduces ACK frequency while ensuring timely confirmation of packet receipt through structured intervals.
2Reliability
If ACK packets are sent frequently to ensure reliable transmission, then packet receipt is confirmed, but transmission resources are consumed and overhead increases
Solution Approach 1:
Multiple individual ACK packets are merged into a single aggregated ACK packet that carries acknowledgment information for multiple data packets. This consolidation reduces the total number of packets transmitted, lowering resource consumption and overhead while maintaining the same level of transmission reliability through comprehensive packet confirmation.
Solution Approach 2:
The aggregated ACK packet serves multiple functions simultaneously: it acknowledges receipt of multiple data packets, provides feedback on packet sequence, and maintains transmission reliability all in a single packet. This multi-functionality reduces the need for multiple separate ACK packets, thereby reducing resource consumption while preserving reliability.
3Reliability
If the traditional ACK mechanism is used, then each packet can be acknowledged individually, but the system cannot adapt to diversified data transmission scenarios such as wireless networks
Solution Approach 1:
The patent introduces dynamic ACK mechanisms that can adjust acknowledgment behavior based on transmission conditions. The system can dynamically switch between individual packet acknowledgment and aggregated acknowledgment modes, adapting to different network scenarios such as wireless networks where resource constraints differ from wired environments. This dynamic adaptability allows the system to maintain reliability while optimizing for diverse transmission scenarios.
Solution Approach 2:
The patent changes key parameters of the ACK mechanism including aggregation level, time intervals, and triggering conditions based on network conditions and transmission requirements. By dynamically adjusting these parameters, the system adapts to diversified scenarios such as wireless networks, maintaining individual packet acknowledgment capability when needed while using aggregated ACKs for efficiency in other scenarios.
