Solution Overview

Problem

The existing Internet structure does not align with actual network utilization patterns, leading to inefficient data routing and reduced network throughput.

Innovation Solution

A terminal device and method that generate and transmit block queries based on content names, using a routing table to search for content segments with matching transmission directions, adjusting block ranges, and setting flags and states to optimize data routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data routing is performed based on traditional Internet host-to-host connection structure, then network infrastructure compatibility is maintained, but network throughput deteriorates due to redundant procedures

Engineering Contradiction:

Improvenetwork throughputVSAvoidrouting procedure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a name resolution system as an intermediary layer between the traditional Internet routing infrastructure and the content-based routing需求. This mediator translates content names into routable addresses, enabling content-based routing without disrupting existing network infrastructure while eliminating redundant routing procedures and improving throughput

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If content segments are transmitted through different routing paths, then routing flexibility is improved, but transmission consistency deteriorates

Engineering Contradiction:

Improverouting path flexibilityVSAvoidtransmission direction consistency

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent performs preliminary routing determination by resolving content names to specific routing paths before transmission begins. This preliminary action establishes consistent transmission directions for all segments of a content block, ensuring stability while still allowing flexibility in the underlying network path selection

Inventive Principle:

Principle #10Preliminary action

AI summary

In a network system based on a content name, a terminal device may generate and transmit a block query requesting a plurality of segments, and may receive segments corresponding to the block query based on a transmission direction of the block query.
