HTTP Header Compression via Preloaded Dictionary for Load Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HTTP protocols are not optimized for latency, leading to significant web page load times due to redundant and uncompressed request and response headers, especially in low-bandwidth connections, and replacing the transport protocol is difficult to deploy.
Innovation Solution
Implementing HTTP header compression by preloading HTTP header keywords into a compression dictionary and compressing relevant fields in the headers using algorithms like gzip or deflate, allowing for efficient transmission over networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If HTTP headers are transmitted without compression, then the protocol remains simple and compatible, but web page load time increases and bandwidth is wasted
Solution Approach 1:
The patent pre-loads HTTP header keywords into a compression dictionary before actual header compression occurs. This preliminary action enables rapid compression during runtime by having the dictionary ready in memory, thus reducing web page load time without adding significant processing complexity during the critical transmission phase.
Solution Approach 2:
The patent transforms HTTP headers from their original uncompressed format to a compressed format using dictionary-based compression algorithms. This parameter change (from uncompressed to compressed) directly reduces the size of transmitted data, decreasing both web page load time and bandwidth consumption while maintaining protocol compatibility through standardized compression methods.
2Loss of energy
If HTTP headers are compressed using a compression dictionary, then bandwidth usage decreases, but the complexity of header processing increases
Solution Approach 1:
The compression dictionary is pre-loaded and prepared in advance, containing frequently occurring HTTP header keywords. This preliminary preparation reduces the computational complexity during actual header compression by having reference data ready, thus minimizing bandwidth usage without proportionally increasing processing complexity.
Solution Approach 2:
The patent uses a compression dictionary that stores copies of common HTTP header keywords and their compressed representations. Instead of computing compression algorithms from scratch for each header, the system references pre-computed dictionary entries, significantly reducing both bandwidth usage and processing complexity.
3Loss of time
If transport protocol is replaced to address latency, then latency performance may improve, but deployment difficulty increases significantly
Solution Approach 1:
The patent introduces HTTP header compression as an intermediary solution between the application layer and transport layer. Rather than replacing the entire transport protocol, it applies compression specifically to HTTP headers, achieving latency reduction while maintaining compatibility with existing TCP transport infrastructure and avoiding complex deployment issues.
Solution Approach 2:
The patent applies compression selectively to HTTP headers rather than transforming the entire transport protocol. This localized approach targets the specific source of latency (header transmission) without requiring system-wide protocol changes, thus improving latency performance while maintaining ease of deployment through incremental implementation.
