Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional Internet communication protocols are used, then basic data transmission is achieved, but network congestion and unpredictable network behavior occur leading to packet loss, duplication, and out-of-order delivery
Solution Approach 1:
The patent introduces intermediate nodes that act as mediators between end devices. These nodes perform functions including buffering data packets, reordering out-of-sequence packets, detecting and requesting retransmission of lost packets, and managing traffic flow to prevent congestion. This intermediary layer shields end devices from network instability while maintaining reliable communication.
Solution Approach 2:
The communication system is segmented into distinct functional components: end devices, intermediate nodes, and network infrastructure. Each intermediate node is further segmented into specialized modules for buffering, reordering, error detection, and traffic management. This segmentation allows each component to optimize its specific function while working together to solve the overall reliability problem.
2Reliability
If more intermediate nodes are deployed to improve communication reliability, then data delivery reliability improves, but device complexity increases
Solution Approach 1:
The intermediate nodes are designed with multi-functionality, serving as buffering devices, packet reorderers, error detectors, and traffic managers simultaneously. This universal design consolidates multiple functions into single nodes, reducing overall system complexity while maintaining high reliability. The nodes can operate autonomously using standardized protocols, further simplifying deployment and management.
3Stability of the object's composition
If intermediate nodes buffer and manage traffic to reduce congestion, then network stability improves, but communication delay increases
Solution Approach 1:
The intermediate nodes employ dynamic traffic management strategies, adjusting buffering rates, reordering thresholds, and retransmission timing based on real-time network conditions. This dynamic approach allows the system to maintain stability during congestion while minimizing delays during normal operation, adapting to changing network states rather than using fixed parameters.
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.
