Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of HTML pages due to multimedia content leads to longer page loading times, as excessive data is written into the protocol stack buffer, causing memory and CPU workload issues.
Innovation Solution
A data writing method that determines whether to-be-transmitted data can be written into a protocol stack buffer based on a stream control parameter and a predetermined threshold value, adjusting the buffer size accordingly to avoid excessive data storage, using a congestion window size and empty area ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If excessive to-be-transmitted data is written into the protocol stack buffer, then the page loading content becomes more complete, but the memory and CPU workload increases, leading to longer page loading times
Solution Approach 1:
The patent implements dynamic buffer size adjustment by monitoring the congestion window size and dynamically changing the protocol stack buffer size accordingly. The buffer size is adjusted in real-time based on network conditions and receiving end capacity, avoiding both excessive data storage and insufficient buffering. This dynamic adaptation resolves the contradiction by making the buffer size flexible rather than fixed, allowing optimal performance across different network states.
Solution Approach 2:
The patent employs feedback mechanisms where the computing device receives congestion window size information from the receiving end and uses this feedback to adjust its buffer size. The system continuously monitors buffer usage, data transmission status, and receiving end capacity, then adjusts the buffer size based on this feedback. This closed-loop control ensures the buffer size remains optimal, preventing both overflow and underutilization, thus resolving the productivity contradiction.
2Reliability
If the protocol stack buffer size is increased to store more data, then data transmission completeness improves, but memory consumption and processing overhead increase
Solution Approach 1:
The patent changes the buffer size parameter dynamically based on the congestion window size and other monitoring parameters. Instead of using a fixed large buffer size, the system adjusts the buffer size parameter in real-time according to actual network conditions and receiving end capacity. This parameter adaptation ensures sufficient buffering for complete data transmission while avoiding the excessive memory allocation and processing overhead that would result from a permanently large buffer.
3Loss of energy
If the buffer size is dynamically adjusted based on congestion window size, then memory efficiency improves, but the control complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-establishing the relationship between congestion window size and buffer size, and by proactively adjusting the buffer size before data transmission issues occur. The system monitors key parameters and adjusts the buffer in advance based on predicted network conditions, rather than reacting to problems after they occur. This preliminary adjustment simplifies the control logic by following predetermined adjustment rules based on monitored parameters.

AI summary
Embodiments of the present application provide techniques for writing data into a buffer of a protocol stack. The disclosed techniques include determining whether to-be-transmitted data are detected; acquiring a stream control parameter from the protocol stack of a computing device in response to a determination that the to-be transmitted data are detected; and determining whether the to-be-transmitted data are able to be written into the buffer of the protocol stack based on the stream control parameter and a predetermined threshold value, wherein the stream control parameter is associated with a capability of receiving data by a data receiving terminal, and the predetermined threshold value is a predetermined ratio of a size value of an empty area of the buffer of the protocol stack to the stream control parameter.
