TCP Acknowledgment Aggregation for Redundant Signal Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies due to the transmission of redundant TCP acknowledgment signals, which waste resources and reduce data throughput, especially in high-speed communication mediums.
Innovation Solution
The system detects and deletes redundant TCP acknowledgment signals before transmission, keeping only the most recent relevant ACK, thereby optimizing the transmission process and reducing the number of ACKs in the stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP acknowledgment signals are transmitted for each received packet, then reliability of data transmission is improved, but resource consumption increases and data throughput decreases
Solution Approach 1:
Multiple TCP acknowledgment signals are merged into a single aggregated acknowledgment packet. The receiver accumulates multiple ACK signals in a queue and transmits them together as one consolidated packet, reducing the total number of transmission events while maintaining acknowledgment coverage for all received data packets.
Solution Approach 2:
The system performs preliminary aggregation of acknowledgment signals before transmission. By pre-processing and consolidating multiple ACKs into a single packet before sending, the system reduces subsequent transmission overhead and improves overall throughput without compromising reliability.
2Reliability
If TCP acknowledgment signals are transmitted for each received packet, then data transmission reliability is improved, but resource wastage increases
Solution Approach 1:
Multiple individual acknowledgment signals are combined into a single aggregated acknowledgment packet, reducing the total number of transmission events. This consolidation decreases energy consumption associated with repeated transmission operations while maintaining complete acknowledgment coverage.
Solution Approach 2:
Redundant individual acknowledgment signals are discarded in favor of a single aggregated acknowledgment packet. The system recovers the essential function of acknowledgment by transmitting consolidated information that covers all received packets, eliminating wasted energy on duplicate transmissions.
3Reliability
If multiple TCP acknowledgment signals are transmitted in high-speed communication, then reliability is improved, but the inefficiency of redundant transmission becomes more significant
Solution Approach 1:
In high-speed communication environments where multiple ACKs may be generated, the system merges these into a single aggregated packet. This approach maintains the reliability benefits of multiple acknowledgments while eliminating the inefficiency of transmitting redundant information across the communication medium.
Solution Approach 2:
The system performs preliminary aggregation of multiple acknowledgment signals before transmission occurs. By consolidating ACKs in advance, the system prevents the loss of transmission efficiency that would otherwise occur in high-speed environments where redundant packets would be transmitted.

AI summary
A method and apparatus according to one embodiment of the invention are operable to detect the accumulation of redundant ACKs (acknowledgment signals) in a queue for streaming data packet units, and to delete a portion of the redundant ACKs to improve transmission efficiencies. In one embodiment, only the most relevant ACK is kept before the ACKs are processed for transmission. In an alternate embodiment, a ratio of defined that limits the maximum number of redundant ACKs that may be deleted. This ratio is based upon a transmission window size. The teachings of the present disclosure may also be applied to flow control in a more general sense in which a plurality of redundant signals responses are being transmitted after being aggregated.
