Solution Overview
Problem
Current Internet communication systems face inefficiencies due to network congestion, traffic load balancing, and unpredictable network behavior, leading to issues like packet loss, duplication, and misordering, which affect data delivery and reliability.
Innovation Solution
Implementing a system that utilizes intermediate nodes capable of functioning as both end-users and intermediate nodes, leveraging advanced protocols like TCP/IP and HTTP to enhance data routing, error correction, and connection management, thereby improving communication efficiency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for reliable data delivery, then data reliability is improved, but network congestion and latency increase
Solution Approach 1:
The system performs preliminary actions by establishing multiple communication paths and pre-positioning intermediate nodes before data transmission begins. This allows data to be routed through alternative paths proactively when congestion is detected, rather than reacting after latency occurs, thus maintaining reliability without excessive delay
Solution Approach 2:
Intermediate nodes are introduced as mediators between end-user devices. These nodes cache data, perform local routing decisions, and manage connection states, thereby reducing the burden on end-to-end TCP protocols and decreasing latency while maintaining data delivery reliability through localized error correction and retransmission
2Productivity
If intermediate nodes are added to improve routing efficiency, then network efficiency is improved, but system complexity increases
Solution Approach 1:
Intermediate nodes are designed to perform multiple functions simultaneously: they act as data relays, local caches, routing decision-makers, and error correction points. This multi-functionality reduces the need for specialized components and simplifies the overall system architecture while improving network efficiency
Solution Approach 2:
Intermediate nodes autonomously make routing decisions based on local network conditions without requiring centralized control. They self-manage connection states, perform local error correction, and dynamically adjust data flow, thereby improving efficiency while minimizing the complexity of network management infrastructure
3Reliability
If error correction mechanisms are implemented, then data reliability is improved, but processing time increases
Solution Approach 1:
Data is segmented into smaller units at intermediate nodes, allowing parallel error checking and correction processing. This segmentation enables multiple error correction operations to occur simultaneously rather than sequentially, maintaining high reliability while reducing overall processing time
Solution Approach 2:
Error detection codes are preliminarily embedded in data packets before transmission. Intermediate nodes perform preliminary error checking upon receipt, identifying and correcting errors immediately rather than waiting for end-to-end acknowledgment, thus maintaining reliability while minimizing delay
Data Source
AI summary
A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The client device accesses an acceleration server to receive a list of available tunnel devices. The requested content is partitioned into slices, and the client device sends a request for the slices to the available tunnel devices. The tunnel devices in turn fetch the slices from the data server, and send the slices to the client device, where the content is reconstructed from the received slices. A client device may also serve as a tunnel device, serving as an intermediate device to other client devices. Similarly, a tunnel device may also serve as a client device for fetching content from a data server. The selection of tunnel devices to be used by a client device may be in the acceleration server, in the client device, or in both. The partition into slices may be overlapping or non-overlapping, and the same slice (or the whole content) may be fetched via multiple tunnel devices.
