Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 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
The use of intermediate nodes that function both as end-users and intermediate nodes to improve communication efficiency, potentially leveraging devices with enhanced capabilities to manage and reroute data packets more effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Internet routing is used, then network coverage is extensive, but network congestion and packet loss increase
Solution Approach 1:
The patent introduces intermediate nodes that act as mediators between end devices and the traditional Internet routing infrastructure. These intermediate nodes receive data from end devices, perform local routing decisions, and forward packets through alternative paths, thereby reducing congestion on traditional routes and improving both reliability and efficiency simultaneously
2Productivity
If more intermediate nodes are deployed, then traffic load balancing improves, but device complexity increases
Solution Approach 1:
The intermediate nodes are designed with multi-functionality, serving both as end devices and as routing intermediaries. This universal design allows the same device to perform multiple roles, reducing the need for dedicated complex infrastructure and lowering overall system complexity while maintaining traffic optimization capabilities
3Productivity
If intermediate nodes with enhanced capabilities are used, then communication efficiency improves, but loss of time for packet processing increases
Solution Approach 1:
The intermediate nodes perform preliminary routing decisions and packet preparation in advance, maintaining ready-state buffers and pre-computed routing tables. This preliminary action allows packets to be forwarded with minimal processing delay when they arrive, improving communication efficiency without significant time loss
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.
