Protocol Overhead Reduction via Static Data Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital broadband broadcast networks face inefficiencies due to significant protocol overhead in packet headers, which wastes bandwidth and resources, as static and inferable data are transmitted within packet headers, unnecessary for data delivery.
Innovation Solution
The solution involves removing static and inferable data from packet headers to generate protocol packets, encapsulating dynamic data with reduced headers, and generating signaling data for reconstructing original packets, thereby reducing protocol overhead and improving network throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static and inferable data are transmitted within packet headers, then data delivery reliability is maintained, but bandwidth efficiency deteriorates due to significant protocol overhead
Solution Approach 1:
The patent extracts static and inferable data from packet headers, separating them from the dynamic data that must be transmitted. This is achieved by identifying header fields that remain constant or can be inferred, removing them from the packet payload, and transmitting only the essential dynamic information, thereby reducing bandwidth consumption while preserving data delivery reliability
Solution Approach 2:
The patent performs preliminary actions by pre-establishing context information that allows the receiver to infer static header data without explicit transmission. The system prepares and transmits minimal signaling data in advance, enabling the receiver to reconstruct complete packet headers through inference, thus eliminating the need to transmit redundant static information
2Reliability
If protocol headers contain complete data, then data integrity is ensured, but network throughput deteriorates due to wasted resources
Solution Approach 1:
The patent uses copying by transmitting a compressed representation of packet headers that contains only essential dynamic information. The receiver creates a copy of the complete header by combining the transmitted dynamic data with pre-established static context, thereby ensuring data integrity while minimizing the amount of data that must be transmitted across the network
Solution Approach 2:
The patent changes the parameter representation by transforming complete packet headers into a compressed format that separates static and dynamic components. Instead of transmitting all header parameters, the system transmits only the dynamic parameters that change between packets, while static parameters are inferred from pre-established context, thus improving network throughput
