Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Internet communication technologies face inefficiencies due to network congestion, traffic load balancing, and unpredictable network behavior, leading to issues such as packet loss, duplication, and out-of-order delivery, which are not effectively addressed by current TCP/IP protocols.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for Internet communication, then standardization and compatibility are achieved, but network congestion and packet loss cannot be effectively addressed
Solution Approach 1:
The patent introduces intermediate nodes as mediators between end devices and the core network. These nodes perform functions including traffic optimization, error correction, and data reassembly, thereby improving reliability without requiring changes to the standard TCP/IP protocol stack. The intermediate nodes absorb the complexity of handling network issues, keeping the end-device implementation simple while achieving enhanced performance.
Solution Approach 2:
The patent segments the network architecture into distinct functional layers: end devices, intermediate nodes, and core network. By dividing the data transmission path into manageable segments with specialized functions, the system can address packet loss and congestion at specific points without redesigning the entire network. Each intermediate node independently handles optimization tasks, improving overall reliability through distributed functionality.
2Reliability
If data is transmitted through multiple intermediate nodes, then packet loss is reduced and delivery reliability is improved, but transmission latency increases
Solution Approach 1:
The patent implements preliminary actions at intermediate nodes by pre-establishing optimized transmission paths and performing proactive error correction. Data is prepared and optimized before potential loss points are encountered, allowing for faster recovery and reducing the need for retransmissions. This preliminary optimization minimizes the time penalty associated with multiple transmission hops.
Solution Approach 2:
The patent ensures continuous data flow through intermediate nodes by implementing parallel processing and pipelining techniques. Multiple data packets are processed simultaneously through different optimization stages, and error correction operates continuously rather than in discrete batches. This continuity maintains high throughput even as data passes through multiple nodes, reducing overall latency.
3Productivity
If intermediate nodes are introduced to optimize traffic, then network efficiency is improved, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent designs intermediate nodes with multi-functional capabilities that can be deployed in various network configurations without requiring custom implementations. Each node can perform multiple functions including routing, optimization, error correction, and caching, allowing a single standardized device type to address multiple network challenges. This universality simplifies deployment by reducing the variety of specialized hardware needed.
Solution Approach 2:
The patent implements self-service mechanisms in intermediate nodes that automatically optimize their configuration based on observed network conditions. Nodes can autonomously adjust transmission parameters, select optimal paths, and coordinate with other nodes without requiring manual configuration or centralized control. This self-configuration capability significantly reduces deployment complexity and allows the network to adapt to changing conditions automatically.
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.
