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 adequately 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 managing network congestion, utilizing advanced protocols to improve data transmission reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If TCP/IP protocols are used for Internet communication, then standardization and compatibility are improved, but network congestion and unpredictable behavior worsen
Solution Approach 1:
The patent introduces an intermediary communication system that operates between end devices and the TCP/IP network infrastructure. This intermediary layer provides enhanced reliability through mechanisms like selective acknowledgment, cumulative acknowledgment, and retransmission requests, while maintaining compatibility with standard TCP/IP protocols. The intermediary acts as a mediator that improves communication reliability without requiring changes to the underlying standardized protocol stack.
2Reliability
If intermediate nodes are added to optimize routing and manage congestion, then data transmission reliability is improved, but device complexity worsens
Solution Approach 1:
The patent describes intermediate nodes that can function both as regular end devices and as communication optimizers simultaneously. These nodes can operate in different modes depending on their configuration and the communication needs, providing multiple functions including routing optimization, congestion management, and reliability enhancement. This multi-functionality reduces the need for separate dedicated optimization infrastructure, thereby limiting the increase in overall system complexity.
3Productivity
If advanced protocols are implemented at intermediate nodes, then productivity is improved, but device complexity worsens
Solution Approach 1:
The patent divides the communication system into distinct functional layers: standard TCP/IP protocol handling at the base level, and optional advanced communication protocols operating at an intermediate layer. This segmentation allows intermediate nodes to implement productivity-enhancing features like selective acknowledgment and cumulative acknowledgment without requiring complete redesign of the entire protocol stack. The modular approach enables selective activation of advanced features based on network conditions and device capabilities.
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.
