Packet Wash Intermediary Nodes Reduce Network Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face inefficiencies due to retransmissions of corrupted or congested data packets, which waste network resources and increase latency.
Innovation Solution
The implementation of a packet wash operation, where intermediary network nodes modify the size of data packets by removing or adding data payload portions based on attributes and network conditions, allowing for reduced packet size and latency without the need for retransmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If packet retransmission is performed when confirmation of successful receipt is not received, then data reliability is improved, but network resource usage increases and communication latency increases
Solution Approach 1:
The patent applies preliminary action by performing packet washing at intermediary network nodes before packets are discarded due to congestion or errors. The washing operation proactively removes or modifies payload portions that are likely to cause transmission failures, thereby preventing retransmissions and conserving network resources while maintaining delivery reliability.
2Reliability
If packet retransmission is performed when confirmation of successful receipt is not received, then data reliability is improved, but communication latency increases

The washing operation proactively removes or modifies payload portions that are likely to cause transmission failures, thereby preventing retransmissions and conserving network resources while maintaining delivery reliability.
3Loss of energy
If packet wash operation is performed to modify packet size, then network resource usage is reduced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the packet payload into multiple portions and applying different washing operations to different segments based on their importance and network conditions. This allows the intermediary node to perform selective modification rather than processing the entire packet uniformly, reducing overall complexity while maintaining resource efficiency.
Solution Approach 2:
The patent applies local quality by applying different washing strategies to different portions of the packet payload based on their characteristics and importance. Critical payload portions receive different treatment than non-critical portions, allowing the intermediary node to optimize resource usage without requiring complex global processing of the entire packet.
4Loss of time
If packet wash operation is performed to reduce packet size, then communication latency is reduced, but data completeness may be compromised
Solution Approach 1:
The patent applies local quality by applying different washing strategies to different portions of the packet payload based on their characteristics and importance. Critical payload portions receive different treatment than non-critical portions, allowing the intermediary node to optimize resource usage without requiring complex global processing of the entire packet.
Solution Approach 2:
The patent applies discarding and recovering by selectively removing non-critical payload portions during packet washing while maintaining the ability to recover or reconstruct the original data if needed. The intermediary node identifies and discards redundant or less important data portions, reducing latency while preserving essential information for potential recovery.
Data Source
AI summary
A method for communicating a data packet, the method includes receiving a data packet that supports a packet wash operation. The method determines whether the data packet can be forwarded along a network path towards a destination node without any modification. If the data packet cannot be forwarded along the network path towards the destination node without modification, the method determines whether conditions are met for performing the packet wash operation on the data packet. If the conditions are met, the packet wash operation is performed to generate a washed data packet. The packet wash operation generates the washed data packet by modifying a size of a payload of the data packet based on a packet wash specification that associates attributes to a plurality of data payload portions of the payload of the data packet. The washed data packet is forwarded along the network path towards the destination node.
