Protocol Stack Application-Layer Control for Low-Delay Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network communication methods fail to effectively utilize application layer information for data transmission, leading to increased delays and reduced user experience due to the need for additional communication links and hijacking of traffic for management, which is inefficient in managing application-oriented requirements.
Innovation Solution
A data transmission method that processes service packets based on application layer information within the protocol stack, allowing for application-oriented management and control without establishing additional communication links, using a control policy library to determine the appropriate actions for service packets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traffic is hijacked to standalone management software for application-oriented management, then application layer information can be utilized for data transmission, but additional communication links are established causing increased delay
Solution Approach 1:
The patent merges the management functionality directly into the protocol stack by adding an application layer module, eliminating the need for separate standalone management software. This integration allows application layer information to be accessed and processed within the existing communication path, thereby achieving application-oriented management without introducing additional communication links or delays.
Solution Approach 2:
The protocol stack is enhanced to perform multiple functions: it maintains its traditional networking capabilities while simultaneously incorporating application layer processing capabilities. The application layer module within the protocol stack can handle both standard protocol operations and application-specific management tasks, eliminating the need for separate management software and reducing communication overhead.
2Adaptability or versatility
If traffic is hijacked to standalone management software, then application layer information can be processed, but the original sidelink between services is changed to three communication links
Solution Approach 1:
The patent combines the application layer processing functionality directly within the protocol stack, merging what would otherwise be separate management software into the existing communication infrastructure. This integration maintains the original direct sidelink between services while enabling application layer information processing, thereby avoiding the complexity of three separate communication links.
3Productivity
If layer 4 management is used based on IP address and port information, then traffic management can be performed, but application information above the transport layer cannot be utilized
Solution Approach 1:
The patent segments the protocol stack by adding a distinct application layer module that operates above the transport layer. This segmentation allows the system to maintain efficient layer 4 traffic management based on IP addresses and ports while simultaneously enabling access to and processing of application layer information through the newly added module, thus achieving both objectives without conflict.

AI summary
Embodiments of this application provide a data transmission method and apparatus. The method is applied to a communication process between a first service and a second service, and a protocol stack invoked by the first service performs operations including: obtaining first application information of a service packet transmitted between the first service and the second service, where the first application information includes application layer information; and processing the service packet based on the first application information and a first control policy library, where the first control policy library indicates a manner for processing the service packet. According to solutions in embodiments of this application, application-oriented link-associated management and control can be implemented in a data transmission process. This ensures service access experience.
