Find Innovative SolutionsGenerate Solutions
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 intermediate nodes that can function both as end-users and intermediate nodes, utilizing advanced protocols like TCP/IP and HTTP to enhance communication by optimizing network traffic management and error correction, enabling persistent connections for improved data transfer efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for reliable data delivery, then data transmission reliability is improved, but network congestion and latency increase
Solution Approach 1:
The patent establishes persistent TCP connections between intermediate nodes before data transfer is needed. By pre-establishing these connections during idle periods, the system avoids the time-consuming connection setup process (handshake) when actual data transfer occurs, thereby reducing latency while maintaining reliable TCP-based transmission
Solution Approach 2:
The patent introduces intermediate nodes that act as mediators in the data transmission path. These nodes pre-establish persistent connections with both clients and servers, buffering and forwarding data through these pre-configured reliable TCP channels. This intermediary approach distributes the connection management burden and reduces end-to-end latency while maintaining transmission reliability
2Productivity
If persistent connections are established for improved data transfer efficiency, then communication efficiency is improved, but network resource consumption increases
Solution Approach 1:
The patent makes intermediate nodes doubly functional by enabling them to act both as end-users (clients) and as intermediate relay points simultaneously. This multi-functionality allows a single node to maintain persistent connections with multiple partners, amortizing the connection overhead across multiple data transfers and reducing per-transfer resource consumption while maintaining high efficiency
Solution Approach 2:
The intermediate nodes autonomously manage their own persistent connections, including establishing, maintaining, and tearing down connections based on traffic patterns. This self-service capability eliminates the need for external connection management overhead and allows nodes to optimize their own resource usage, balancing efficiency gains against resource consumption
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.
