Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for Internet communication, then data transmission reliability is improved through error checking and retransmission, but network congestion and packet loss increase due to the overhead of connection management and protocol processing
Solution Approach 1:
The patent introduces intermediate nodes (relay devices) that act as mediators between end-user devices. These intermediate nodes pre-establish TCP connections and buffer data, eliminating the need for direct TCP handshaking between all pairs of end devices. This reduces protocol overhead and connection management burden on the network, thereby improving transmission speed while maintaining reliability through the intermediary's buffer and error handling capabilities.
Solution Approach 2:
The patent implements pre-establishment of TCP connections at intermediate nodes before actual data transmission between end users. By performing connection setup, authentication, and buffer allocation in advance, the system eliminates real-time protocol negotiation overhead during data transfer, thus improving network productivity while maintaining the reliability benefits of TCP through pre-configured error handling and retransmission mechanisms.
2Productivity
If intermediate nodes are introduced to improve communication efficiency, then network congestion is reduced and data transmission speed is improved, but device complexity increases due to the need for dual functionality as both end-user and intermediate node
Solution Approach 1:
The patent designs intermediate nodes with multi-functionality, allowing them to operate both as end-user devices and as relay nodes. This universal design enables a single device type to perform multiple roles in the network, reducing the need for specialized hardware and simplifying deployment. The device can dynamically switch between consuming data (end-user mode) and forwarding data (intermediate node mode), thereby improving communication efficiency without requiring entirely separate complex infrastructure.
Solution Approach 2:
The patent combines the functions of end-user devices and intermediate relay nodes into a unified system architecture. By merging these previously separate functional roles into a single deployable device type, the system reduces overall network complexity while achieving improved communication efficiency. The combined device handles both data consumption and data forwarding, eliminating the need for separate specialized infrastructure and simplifying network management.
3Reliability
If TCP connections are established between all end-user devices, then communication reliability is improved, but the number of connections and routing complexity increases significantly
Solution Approach 1:
The patent introduces intermediate nodes as mediators that consolidate multiple TCP connections. Instead of establishing direct TCP connections between all pairs of end-user devices (which would create exponential connection complexity), the intermediate nodes serve as central connection points, maintaining TCP connections with end users and buffering data between them. This reduces the number of active TCP connections from O(n²) to O(n), significantly simplifying connection management while maintaining communication reliability through the intermediary's connection handling 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.
