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, utilizing advanced protocols like TCP/IP and HTTP to enhance communication by optimizing packet routing, error correction, and connection management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional TCP/IP protocols are used for internet communication, then basic data transmission is achieved, but network congestion and unpredictable network behavior cause packet loss, duplication, and misordering
Solution Approach 1:
The patent introduces an intermediary system that sits between the application layer and the TCP/IP stack, acting as a mediator to manage packet transmission. This intermediary tracks packet states, coordinates retransmissions, and ensures proper ordering, thereby resolving the reliability issues caused by network congestion and unpredictable behavior without requiring changes to the underlying TCP/IP protocols.
Solution Approach 2:
The patent implements a feedback mechanism where the intermediary continuously monitors packet transmission status, receives acknowledgments, and adjusts retransmission decisions based on real-time network conditions. This feedback loop enables dynamic adaptation to network congestion, preventing packet loss and duplication by making informed retransmission decisions based on actual network state rather than relying solely on standard TCP protocols.
2Productivity
If standard internet protocols are used, then communication is maintained, but network congestion reduces communication efficiency and speed
Solution Approach 1:
The patent employs preliminary action by pre-establishing communication channels and pre-coordinating packet transmission schedules before actual data transfer begins. The intermediary prepares transmission paths, allocates resources, and sets up error correction mechanisms in advance, enabling faster and more efficient data transmission during actual communication without being constrained by network congestion that would affect standard protocols.
3Reliability
If intermediate nodes are introduced to improve reliability, then packet loss is reduced, but system complexity increases
Solution Approach 1:
The patent applies universality by designing the intermediary to perform multiple functions within a single system component. The intermediary simultaneously handles packet tracking, error correction, retransmission management, and ordering, thereby improving communication reliability without proportionally increasing system complexity. This multi-functional approach consolidates what would otherwise require multiple separate components into a single integrated solution.
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.
