Packet Boundary Detection Using Dual Placeholders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication protocols, such as TCP/IP, incur computational and complexity overheads, which can be beyond the capabilities of some systems and resources, making it difficult for them to effectively transmit and receive data without hardware or software resources like computational power and storage.
Innovation Solution
The method involves generating boundary identifiers using placeholders within packets, where a short placeholder is calculated over a fixed-sized window and a long placeholder is based on the entire packet, allowing the receiver to confirm packet boundaries and identify individual packets by matching check-values with placeholders, even in systems with limited resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication protocols like TCP/IP are used to ensure data integrity and proper transmission, then reliability of data transmission is improved, but computational overhead and device complexity increase significantly
Solution Approach 1:
The patent extracts the essential boundary detection functionality from complex communication protocols by implementing a standalone placeholder detection mechanism. The receiver independently verifies packet boundaries using placeholders embedded in the data stream, eliminating the need for full TCP/IP protocol stacks and reducing device complexity while maintaining transmission reliability.
Solution Approach 2:
The patent introduces placeholders as intermediary markers within the data stream to indicate packet boundaries. These placeholders serve as mediators that enable the receiver to identify packet boundaries without requiring complex protocol processing, thus reducing computational overhead while ensuring reliable data reception.
2Reliability
If full communication protocol stacks are implemented to handle error recovery and data integrity, then data transmission reliability is improved, but use of computational resources and power increases
Solution Approach 1:
The patent extracts only the necessary boundary detection functionality from full protocol stacks, implementing a lightweight placeholder verification mechanism. This approach maintains data integrity by reliably identifying packet boundaries while consuming minimal computational resources and power, making it suitable for resource-constrained devices.
Solution Approach 2:
The patent uses simple placeholder markers as disposable indicators for packet boundaries. These placeholders are lightweight computational objects that can be quickly generated and verified without requiring sustained computational resources, thereby reducing power consumption while ensuring reliable packet identification.
3Measurement precision
If complex protocol processing is used to identify packet boundaries and ensure proper reception, then measurement precision of packet boundaries is improved, but computational overhead increases
Solution Approach 1:
The patent introduces placeholders as intermediary markers that explicitly indicate packet boundaries within the data stream. The receiver detects these placeholders to precisely identify packet boundaries without requiring complex protocol processing, thereby maintaining high measurement precision while reducing processing complexity.
Solution Approach 2:
The patent embeds placeholder copies within the data stream that replicate boundary information in a simplified form. These placeholder copies enable the receiver to accurately detect packet boundaries through simple pattern matching rather than complex protocol analysis, preserving detection precision while minimizing computational overhead.
