Solution Overview
Problem
Current internet communication systems face challenges in efficiently managing network congestion and ensuring reliable data transfer due to unpredictable network behavior, leading to issues like packet loss, duplication, and out-of-order delivery, which affect the overall performance and reliability of data transmission.
Innovation Solution
The implementation of a system that utilizes intermediate nodes capable of functioning as both end-users and intermediate nodes, leveraging advanced protocols such as TCP/IP and HTTP, to enhance communication by optimizing network traffic management and error correction mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If intermediate nodes are used to manage network traffic, then network congestion is reduced and communication efficiency is improved, but device complexity increases as devices must function as both end-users and intermediate nodes
Solution Approach 1:
The patent enables devices to perform multiple functions by allowing them to operate as both end-users and intermediate nodes in the network. This multi-functionality is achieved through implementing protocol stacks and processing logic that can handle both data transmission for local applications and network traffic management for relayed communications, thereby improving communication efficiency without requiring separate dedicated infrastructure
2Reliability
If advanced error detection and correction mechanisms are implemented, then data transfer reliability is improved, but processing time and computational resources increase
Solution Approach 1:
The patent implements error detection and correction codes during the data transmission process itself, performing error checking proactively as data packets are transmitted through intermediate nodes. This preliminary action approach allows for real-time error detection and correction without requiring separate post-transmission verification steps, thereby maintaining high data transfer reliability while minimizing additional processing time
3Adaptability or versatility
If intermediate nodes relay data packets between end-users, then network coverage and connectivity are improved, but the risk of packet loss, duplication, and out-of-order delivery increases due to unpredictable network behavior
Solution Approach 1:
The patent implements feedback mechanisms where intermediate nodes and end-users exchange acknowledgment packets to confirm successful data reception. When data packets are transmitted through intermediate nodes, the receiving end sends feedback signals indicating whether packets were received correctly, and intermediate nodes use this feedback to retransmit lost or corrupted packets, thereby maintaining data delivery reliability while enabling extended network coverage
Solution Approach 2:
The patent introduces intermediate nodes as mediators that manage data packet transmission between end-users. These intermediate nodes perform functions such as packet routing, error detection, and coordination of retransmissions, acting as intelligent intermediaries that reduce the negative effects of unpredictable network behavior while extending network coverage to areas that would otherwise be unreachable
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 access 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.
