Intermediate Tunnel Nodes for Reliable Internet Content Slicing
Find Innovative SolutionsGenerate Solutions
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 effectively 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 traffic, utilizing advanced protocols to improve data transmission reliability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for Internet communication, then data transmission is achieved, but network congestion and unpredictable network behavior cause packet loss, duplication, and out-of-order delivery
Solution Approach 1:
The patent introduces a mediator layer between the application layer and TCP/IP protocol stack that implements selective acknowledgments (SACK) and manages packet retransmission. This intermediary component processes incoming packets, tracks acknowledged data, and coordinates retransmission requests, thereby resolving the reliability issue caused by packet loss and duplication in TCP/IP networks
2Productivity
If intermediate nodes are added to optimize routing and manage traffic, then data transmission efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements an intermediary component that performs multiple functions within a single module: it manages selective acknowledgments, coordinates retransmissions, tracks packet states, and optimizes routing decisions. By consolidating these functions into one multi-functional component, the system achieves improved data transmission efficiency without proportionally increasing system 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.
