Intermediate Tunnel Nodes for Congestion-Resilient Content Fetching
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 struggle to address effectively.
Innovation Solution
The implementation of intermediate nodes that 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 TCP/IP protocols are used for reliable delivery, then data integrity is improved, but network congestion and packet loss occur due to retransmission requests
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple communication paths and intermediate nodes before data transmission begins. This allows the system to proactively prepare alternative routes, so when congestion or packet loss occurs, retransmission can happen through pre-configured paths rather than waiting for failure detection and route recalculation, thereby maintaining data integrity while improving network efficiency
2Productivity
If intermediate nodes are added to optimize routing, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by designing intermediate nodes that perform multiple functions simultaneously: they act as regular end-user devices for normal communication while also serving as routing intermediaries for optimizing data paths. This multi-functionality allows the system to gain routing optimization benefits without adding dedicated infrastructure, thereby improving network efficiency while minimizing the increase in system complexity
3Reliability
If packet retransmission is implemented for lost data, then data completeness is improved, but transmission time increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple communication paths and intermediate nodes before data transmission begins. This allows the system to proactively prepare alternative routes, so when congestion or packet loss occurs, retransmission can happen through pre-configured paths rather than waiting for failure detection and route recalculation, thereby maintaining data integrity while improving network efficiency
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.
