Network Interface Selection via Reliability Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Selecting an optimal source interface for establishing a connection is challenging due to multiple available options, including wired and wireless interfaces, as well as virtual interfaces, which can vary in reliability and availability across different network locations.
Innovation Solution
A profile is maintained for each network location, containing information about the available network interfaces, including their reliability, to prioritize and select the most suitable interface for connection establishment. If an interface fails, it is de-prioritized, and another interface is selected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple network interfaces are available for connection establishment, then connection options and adaptability are improved, but interface selection complexity increases
Solution Approach 1:
The system performs preliminary actions by maintaining profiles for each network location that contain pre-evaluated reliability information about available interfaces. When a connection is needed, the system queries these pre-prepared profiles to quickly determine the best interface, avoiding the complexity of real-time evaluation of multiple interfaces.
Solution Approach 2:
The system implements feedback mechanisms by monitoring connection success rates for each interface and updating the network location profiles accordingly. Interfaces that successfully establish connections have their reliability scores increased, while failed interfaces have their scores decreased, creating a self-learning system that reduces selection complexity over time.
2Reliability
If interface reliability is prioritized for connection establishment, then connection success rate is improved, but selection time increases due to evaluation requirements
Solution Approach 1:
The system performs reliability evaluations in advance and stores the results in network location profiles. When a connection needs to be established, the system simply queries the pre-evaluated profile data rather than performing new evaluations, significantly reducing selection time while maintaining reliable interface choices.
Solution Approach 2:
The system dynamically updates interface reliability scores based on actual connection outcomes. The profiles adapt to changing network conditions by incorporating feedback from recent connection attempts, allowing the system to maintain high reliability without requiring complete re-evaluation of all interfaces.
Data Source
AI summary
Aspects of the subject matter described herein relate to selecting a source interface with which to establish a connection. In aspects, a profile for each network location a host has seen is maintained in a data store. The profile includes information about the network interfaces available to a source host at the network location. This information indicates, among other things, the reliability of each interface of the source host. Based on the profile, an interface is selected with which to establish a connection. If the interface is unsuccessful in establishing the connection, the interface is de-prioritized and another interface may be selected.
