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 out-of-order delivery, which existing protocols like TCP/IP struggle to address effectively.
Innovation Solution
Implementing intermediate nodes that function both as end-users and intermediate nodes to enhance communication by optimizing TCP/IP protocols, specifically through improved packet routing and error handling mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If TCP/IP protocols are used for Internet communication, then reliable data delivery is achieved, but network congestion and unpredictable network behavior cause packet loss, duplication, and out-of-order delivery
Solution Approach 1:
The patent introduces intermediate nodes (relay devices) between end devices to mediate packet routing. These intermediate nodes receive packets from source end devices, process them (including error detection and correction), and forward them to destination end devices. This intermediary layer helps manage network congestion and improve reliability without requiring changes to the underlying TCP/IP protocol stack.
2Productivity
If traditional end-device architecture is used, then device simplicity is maintained, but communication efficiency and error handling capability are limited
Solution Approach 1:
The patent enables devices to function in multiple roles. End devices can operate as both endpoints and intermediate nodes, and intermediate nodes can also function as end devices. This multi-functionality allows the network to dynamically utilize available devices for packet forwarding, improving communication efficiency without requiring dedicated specialized hardware for each function.
Solution Approach 2:
The patent introduces intermediate nodes as mediating entities in the communication path. These nodes perform packet forwarding, error detection, and correction functions, thereby improving overall communication efficiency and reliability without requiring complex modifications to end devices themselves.
3Adaptability or versatility
If packets are routed through multiple intermediate routers, then network flexibility is improved, but packet loss and delivery errors increase
Solution Approach 1:
The patent introduces specialized intermediate nodes that act as mediating relay devices between traditional routers and end devices. These nodes perform error detection and correction on packets, thereby maintaining the routing flexibility provided by multiple intermediate routers while improving packet delivery accuracy through active error management at the intermediate node level.
Solution Approach 2:
The patent implements feedback mechanisms where intermediate nodes monitor packet conditions and can request retransmission of corrupted packets. This feedback loop allows the system to detect and correct errors that occur during routing through multiple intermediaries, maintaining both flexibility and reliability.
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.
