Find Innovative SolutionsGenerate Solutions
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 out-of-order delivery, which existing protocols struggle to address effectively.
Innovation Solution
The implementation of intermediate nodes that function both as end-users and intermediate nodes, utilizing advanced protocols like TCP/IP and HTTP to enhance communication by optimizing packet routing, error detection, and retransmission mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for reliable data delivery, then data integrity is improved, but network congestion and packet loss occur due to retransmission requests
Solution Approach 1:
The patent introduces intermediate nodes (relay devices) between end devices to handle packet routing and retransmission. These intermediaries buffer and forward packets, reducing the burden on end-to-end TCP retransmission mechanisms and decreasing network congestion caused by repeated retransmission requests across the entire network path.
Solution Approach 2:
The network communication is segmented into multiple hops through intermediate nodes. Instead of direct end-to-end communication where lost packets trigger network-wide retransmission, the path is divided into smaller segments managed by individual relay devices, localizing the impact of packet loss and reducing overall network congestion.
2Productivity
If intermediate nodes are used to improve routing efficiency, then network efficiency is improved, but device complexity increases due to dual functionality requirements
Solution Approach 1:
The patent designs intermediate nodes with dual functionality: they can operate as end devices for local communication and as relay nodes for forwarding packets. This multi-functionality allows the same hardware to serve multiple purposes, improving network efficiency without requiring separate dedicated relay infrastructure, thereby managing device complexity through versatile design.
3Reliability
If packet retransmission is implemented for lost packets, then data reliability is improved, but transmission time increases due to retransmission delays
Solution Approach 1:
Intermediate nodes perform preliminary actions by buffering packets and proactively managing retransmission before packets are completely lost or timing out. The relay devices can retransmit packets locally without waiting for end-to-end acknowledgment failures, reducing the overall transmission delay while maintaining data reliability.
Solution Approach 2:
The system implements feedback mechanisms where intermediate nodes monitor packet delivery status and dynamically adjust retransmission behavior. This feedback allows the network to respond to actual delivery conditions, retransmitting only when necessary and reducing unnecessary delays from blanket retransmission protocols.
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.
