Message Header Extraction for Network Protocol Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, messages often include unnecessary headers that can cause invalid responses, exceed message size limits, and expose sensitive information, leading to security breaches and inefficiencies.
Innovation Solution
A system and method that modify messages by adding and removing specific headers, such as SIP Via or record route headers, within a container environment, allowing proprietary information to be stored and inserted as needed, ensuring only necessary information is transmitted across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If protocols add additional headers to messages, then protocol-specific functionality is enabled, but message size increases and may exceed maximum limits
Solution Approach 1:
The patent extracts and removes unnecessary headers from messages before transmission. The message processor identifies and strips out headers that are not needed for the specific communication context, reducing message size while preserving essential protocol functionality.
Solution Approach 2:
The patent applies partial action by selectively adding or removing only the specific headers that are necessary for the given communication scenario, rather than processing all headers uniformly. This optimizes message size while maintaining required protocol capabilities.
2Adaptability or versatility
If local headers are added for specific protocol requirements, then local device functionality is improved, but remote devices may not know how to handle these headers
Solution Approach 1:
The message processor acts as an intermediary between local and remote devices. It adds necessary local headers for protocol functionality, then removes or modifies them before transmission to ensure compatibility with remote devices that may not recognize these headers.
Solution Approach 2:
The patent segments header processing into distinct stages: adding headers for local protocol requirements, processing the message body, then removing unnecessary headers before transmission. This segmentation allows local functionality to be maintained while ensuring remote compatibility.
3Productivity
If message size is reduced by removing headers, then transmission efficiency is improved, but necessary protocol information may be lost
Solution Approach 1:
The message processor uses feedback mechanisms to determine which headers to remove. It analyzes the message content, communication context, and protocol requirements to intelligently identify which headers can be safely removed without losing necessary protocol information, optimizing transmission efficiency while preserving essential data.

AI summary
A first message associated with a first communication session is received at a container. The first message is modified by adding a new header. The first message may be processed in the container. At least a portion of the new header is removed from the modified message. The removed portion of the new header is stored. The modified message without the removed portion is sent outside the container. A second message associated with the first communication message is received at the container. The stored portion of the new header is inserted into the second message. The second message with the inserted portion of the new header is processed in the container. The portion of the new header is removed from the second message and the second message is sent outside the container.
