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 devices that can function as both end-users and intermediate nodes to optimize TCP/IP protocols, enhancing connection management and data routing through improved packet handling and error correction mechanisms.
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 intermediate nodes (proxy servers, caching servers, gateway servers) that act as mediators between end-user devices and destination servers. These intermediaries manage TCP connections, perform packet inspection, and handle error correction, thereby resolving the technical contradiction by providing an additional layer of control and reliability in the communication path.
Solution Approach 2:
The patent segments the Internet communication path into multiple independent segments managed by different intermediate nodes. Each node handles specific functions (caching, proxying, gateway services) and can independently manage packet flow, error correction, and retransmission for its segment, improving overall reliability without requiring changes to the entire network infrastructure.
2Reliability
If intermediate nodes are introduced to improve communication reliability, then packet handling and error correction are enhanced, but system complexity increases
Solution Approach 1:
The patent designs intermediate nodes with multiple functions integrated into single devices. Proxy servers can also act as caching servers; gateway servers can provide both routing and security functions. This multi-functionality reduces the total number of devices needed and simplifies system management while maintaining improved reliability.
Solution Approach 2:
The patent combines multiple intermediate node functions into unified server systems that can handle proxying, caching, gateway services, and error correction simultaneously. This merging approach reduces infrastructure complexity and makes the system more manageable while preserving the reliability benefits of having intermediate nodes.
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.
