Private Network Request Forwarding via Intermediary Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public network infrastructure exposes content providers to vulnerabilities, such as denial of service attacks, as illegitimate requests can directly reach content providers without filtering, disrupting services and causing potential financial and physical damages.
Innovation Solution
Implementing a private network infrastructure that analyzes requests through access profiles to determine legitimacy, filtering out illegitimate requests and forwarding only legitimate ones to content providers, thereby limiting user access and protecting against threats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If public network infrastructure is used to deliver requests to content providers, then service accessibility and ease of operation are improved, but security and reliability deteriorate due to exposure to illegitimate requests and denial of service attacks
Solution Approach 1:
The patent introduces a content delivery entity as an intermediary between users and content providers. This entity receives requests from users over the public network, analyzes them for legitimacy, and forwards only legitimate requests to content providers through a private network. The intermediary thus enables public access while protecting against security threats by filtering malicious requests before they reach the content provider infrastructure.
2Ease of operation
If direct access to content providers is allowed over public network, then ease of operation is improved, but harmful factors increase due to unfiltered illegitimate requests
Solution Approach 1:
The content delivery entity performs preliminary analysis of requests before they are forwarded to content providers. By analyzing access profiles and determining legitimacy in advance, the system prevents illegitimate requests from reaching content providers. This preliminary filtering action eliminates harmful factors while maintaining convenient access for legitimate users.
3Reliability
If private network infrastructure with request analysis is implemented, then security and reliability are improved, but device complexity and infrastructure requirements worsen
Solution Approach 1:
The patent segments the network infrastructure into distinct functional components: a public network interface for receiving requests, a content delivery entity with analysis capabilities, and a private network for forwarding legitimate requests. This segmentation allows the complex security functions to be isolated in a dedicated entity, making the overall system more manageable and the complexity localized rather than distributed throughout the entire network.

AI summary
Private network request forwarding can include receiving a request from a user for Internet services over a public network. Private network request forwarding can include analyzing the request and determining whether the request is legitimate. Private network request forwarding can include forwarding the request to an entity through a private network when it is determined that the request is legitimate, wherein the user has access to the entity through a proxy.
