Interest Segmentation in Information Centric Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information centric networks, existing methods face challenges in efficiently forwarding large amounts of data and managing communication between low-speed and high-speed lines, leading to communication delays and inefficiencies due to the combination of 1-to-N and one-to-one communication models.
Innovation Solution
The method involves separating interests into simple and complex interests, where the communication control apparatus sends request content data via a low-speed path and matching target data via a high-speed path, allowing content accumulating devices to match and respond efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If matching target data is added to the interest in information centric network, then the content matching accuracy is improved, but the communication delay increases and communication stability deteriorates due to large data volume on low-speed lines
Solution Approach 1:
The patent segments the interest message into two separate parts: simple interest (containing only request content data) and complex interest (containing matching target data). This segmentation allows the simple interest to be transmitted quickly on low-speed lines for content accumulation device identification, while the complex interest with large matching target data is transmitted separately to avoid blocking the main search process, thereby reducing communication delay while maintaining matching accuracy.
Solution Approach 2:
The patent introduces a communication control apparatus as an intermediary between the information collector and content accumulation devices. This intermediary receives the original interest, separates it into simple and complex interests, and manages their transmission on different communication paths. The intermediary coordinates the arrival of both interest types at the content accumulation device, ensuring proper association without requiring the entire interest to traverse the slow path, thus reducing communication delay.
2Measurement precision
If matching target data is added to the interest, then the content matching capability is improved, but the communication stability deteriorates on low-speed lines
Solution Approach 1:
By segmenting the interest into simple and complex parts, the patent ensures that the critical simple interest (which routes the search request) is transmitted on low-speed lines without being blocked by large matching target data. The complex interest with matching target data is transmitted separately, preventing communication disruption on low-speed lines while maintaining the ability to perform accurate matching at the content accumulation device upon receipt of both parts.
Solution Approach 2:
The communication control apparatus acts as a mediator that manages the separate transmission of simple and complex interests. It ensures that both parts reach the content accumulation device reliably and coordinates their association, thereby maintaining communication stability on low-speed lines while preserving the complete matching capability through proper reassembly at the destination.
3Device complexity
If the same communication line is used for both interest transmission and content delivery, then the system simplicity is maintained, but the communication efficiency deteriorates due to high-speed line requirement
Solution Approach 1:
The patent introduces a new dimension by separating the communication paths into at least two distinct channels: one for interest transmission and another for content delivery. This dimensional separation allows the interest (with small overhead) to traverse low-speed lines efficiently while the large-volume content can utilize high-speed lines, thereby improving communication efficiency without significantly increasing system complexity as the separation is managed through protocol design rather than physical infrastructure changes.
4Adaptability or versatility
If 1-to-N communication is used for content requests, then the search coverage is improved, but the communication efficiency deteriorates when combined with one-to-one content delivery
Solution Approach 1:
The patent segments the communication process into two phases: the interest transmission phase using 1-to-N communication for broad search coverage, and the content delivery phase using optimized 1-to-1 communication for efficient data transfer. By separating these phases and optimizing each independently, the system maintains wide search coverage while improving overall communication efficiency through appropriate protocol selection for each communication pattern.
Data Source
AI summary
A user terminal sends out an interest including text data and an image file for matching to an information centric network. When a server receives the interest from the user terminal, the server separates the image file for matching from the interest and sends out a simple interest that includes the text data and does not include the image file for matching and a complex interest that includes the image file for matching to the information centric network. A camera associates the text data included in the simple interest with the image file for matching included in the complex interest, executes a matching process for verifying whether any of the image files accumulated in the own device matches the image file for matching based on the criteria stipulated in the text data, and transmits a matching result report to the user terminal.
