Solution Overview
Problem
Current communication technologies over the Internet face challenges in efficiently managing network congestion, traffic load balancing, and unpredictable network behavior, leading to issues such as packet loss, duplication, and out-of-order delivery.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If intermediate nodes are used to manage and optimize data transmission, then communication efficiency and data delivery reliability are improved, but device complexity and network management complexity increase
Solution Approach 1:
The patent applies multi-functionality by enabling devices to serve dual roles as both end-users and intermediate nodes. This allows a single device to perform multiple functions: consuming data as an end-user while simultaneously relaying and optimizing data transmission for other nodes, thereby improving reliability without proportionally increasing overall system complexity
Solution Approach 2:
The patent introduces intermediate nodes as mediators between end-users and the core network. These nodes buffer, cache, and forward data packets, improving data delivery reliability by reducing direct network dependencies and providing local redundancy, while distributing complexity across multiple nodes rather than concentrating it in a single controller
2Productivity
If intermediate nodes buffer and cache data packets, then network congestion is reduced and traffic flow is optimized, but memory usage and energy consumption increase
Solution Approach 1:
The patent implements partial buffering by caching only frequently accessed or critical data packets at intermediate nodes rather than buffering all traffic. This selective caching approach optimizes traffic flow for high-demand data while limiting memory usage and energy consumption to only the necessary portions
Solution Approach 2:
The patent dynamically adjusts buffering parameters such as cache size, retention time, and prioritization criteria based on network conditions, traffic patterns, and energy availability. This allows the system to optimize traffic flow efficiency while adapting energy consumption to actual operational needs rather than maintaining fixed high-resource allocation
3Productivity
If devices function as both end-users and intermediate nodes, then network resource utilization is improved and communication efficiency increases, but device operational complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where devices automatically discover their dual roles, configure their buffering and relaying parameters, and manage their own data packets without manual intervention. This automation reduces the perceived operational complexity for users while maintaining high communication efficiency through intelligent local decision-making
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.
