Tunnel Node Content Slicing for Reliable Internet Fetching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Internet communication systems 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
Implementing intermediate nodes that function as both end-users and intermediate nodes to enhance communication by optimizing data routing and reducing network congestion through advanced data segmentation and reassembly techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for Internet communication, then reliable data delivery is achieved, but network congestion and unpredictable network behavior cause packet loss, duplication, and out-of-order delivery
Solution Approach 1:
The patent introduces intermediate nodes (content delivery network elements) as mediators between end users and content sources. These intermediaries cache, segment, and manage data delivery, reducing direct traffic on core network paths and improving overall communication efficiency while maintaining reliability through coordinated data transfer protocols
2Productivity
If intermediate nodes are introduced to optimize routing and reduce congestion, then communication efficiency improves, but system complexity increases
Solution Approach 1:
The patent designs intermediate nodes with multiple functions: they act as content cache, data segmenter, reassembly point, and routing optimizer. By consolidating these functions into unified intermediate nodes rather than separate specialized components, the system achieves improved communication efficiency without proportionally increasing overall system complexity
3Reliability
If advanced data segmentation and reassembly techniques are implemented, then packet loss and latency are minimized, but processing overhead increases
Solution Approach 1:
The patent performs data segmentation at the intermediate nodes before transmission, organizing data into pre-defined segments with metadata. This preliminary organization enables more efficient routing and reduces the need for complex real-time processing during transmission, minimizing packet loss and latency while controlling processing overhead through advance preparation
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.
