Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Internet communication systems face inefficiencies due to network congestion, traffic load balancing, and unpredictable network behavior, leading to issues like packet loss, duplication, and misordering, which affect data transmission reliability and speed.
Innovation Solution
Implementing intermediate nodes that can function both as end-users and intermediate nodes to optimize data routing and transmission, utilizing advanced protocols like TCP/IP and HTTP to enhance communication efficiency through improved packet handling and routing strategies.
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-user devices. These nodes receive data packets, process them through virtual machine instances, and forward them through optimized routing paths. This intermediary layer resolves the contradiction by providing both reliability (through error checking, retransmission, and multiple path options) and productivity (through efficient routing and reduced congestion) simultaneously.
2Productivity
If more routing paths are used to avoid congestion, then data transmission speed improves, but packet misordering and loss increase
Solution Approach 1:
The patent segments data transmission into multiple virtual channels through virtual machine instances. Each segment can be routed independently through different paths while maintaining proper sequencing and acknowledgment. This allows high-speed parallel transmission while ensuring reliability through segment tracking and reassembly at the destination.
Solution Approach 2:
The system implements feedback mechanisms where intermediate nodes and end devices send acknowledgment packets and status information back through the network. This feedback loop enables real-time monitoring of packet delivery, allowing the system to detect misordered or lost packets and trigger retransmission, thus maintaining high delivery accuracy even when using multiple routing paths for speed.
3Reliability
If intermediate nodes are added to optimize routing, then communication reliability improves, but network complexity increases
Solution Approach 1:
The patent designs intermediate nodes with multi-functionality, where virtual machine instances can perform multiple roles: routing decisions, error checking, data segmentation, and feedback generation. This universality reduces the need for separate specialized components, thereby improving communication reliability while limiting the increase in overall network complexity.
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.
