Network Device Communication Aggregation via Synchronized Proxy Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In client environments where multiple devices are introduced and individual Internet connections are not permissible for security reasons, existing systems face challenges in synchronizing the switching of proxy information across devices, leading to potential security vulnerabilities and lack of communication aggregation state notification to management servers.
Innovation Solution
A network device with processors and memory that manages proxy information and communicates via a proxy server, enabling synchronized switching of proxy information and communication aggregation modes, ensuring secure communication paths and timely notification of aggregation states to management servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If proxy information is switched sequentially for each device, then each device can obtain proxy information individually, but communication paths cannot be synchronized and security is compromised
Solution Approach 1:
The management server provides a notification to the monitoring apparatus before proxy information switching occurs. The monitoring apparatus then notifies all devices simultaneously using this advance notification, ensuring all devices switch to the new proxy information at the same time, thereby synchronizing the switching process and maintaining communication security.
2Adaptability or versatility
If devices are connected individually to the Internet, then each device has direct access, but security operation and management becomes difficult
Solution Approach 1:
The patent introduces a monitoring apparatus as an intermediary (proxy server) between devices and the Internet. All devices route their communications through this monitoring apparatus, which aggregates their traffic. This intermediary structure enables centralized security management while maintaining device connectivity to the Internet.
3Reliability
If proxy information is switched all together at a specific timing, then communication security is maintained, but devices cannot obtain proxy information independently
Solution Approach 1:
The management server sends a notification to the monitoring apparatus about the upcoming proxy information switching. The monitoring apparatus uses this feedback information to coordinate and notify all devices simultaneously. This feedback mechanism enables synchronized switching while allowing devices to obtain proxy information through the monitoring apparatus rather than independently.
Data Source
AI summary
A network device includes one or more memories and one or more processors. The one or more processors and the one or more memories are configured to obtain proxy information set to the network device, and communicate with a management server via a proxy server using the proxy information in a case where an aggregation mode is enabled and the proxy information is information received from the proxy server or in a case where the aggregation mode is not enabled, and not to communicate with the management server in a case where the aggregation mode is enabled and the proxy information is not the information received from the proxy server.
