Solution Overview

Problem

Managing inbound and outbound network traffic for virtual machines is challenging due to the difficulty in configuring firewall and network management resources, especially when different applications are attached and made available based on current requirements.

Innovation Solution

A method is introduced to identify the attach process of applications to virtual machines, identify corresponding firewall rules, and provide them to a networking manager for implementation, enhancing network traffic management by dynamically applying firewall rules at the virtual network interface or other data paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If application volumes are attached to virtual machines to provide required applications to users, then application availability and user satisfaction are improved, but firewall and network traffic management complexity increases

Engineering Contradiction:

Improveapplication availabilityVSAvoidfirewall configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Firewall rules are pre-configured and associated with application volumes before they are attached to virtual machines. When an application volume is attached, the corresponding firewall rules are automatically applied. This preliminary preparation eliminates the need for complex manual firewall configuration when applications are dynamically attached, resolving the contradiction between application availability and firewall management complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables automatic application of firewall rules based on application volume attachment events. The networking manager automatically identifies when an application volume is attached and applies the corresponding pre-configured firewall rules without requiring manual intervention. This self-service mechanism resolves the technical contradiction by making the system adapt to changing application requirements while automatically managing the associated network security complexity.

Inventive Principle:

Principle #25Self-service

2Reliability

If manual firewall configuration is used for each application attached to virtual machines, then network security can be customized, but time consumption and operational overhead increase

Engineering Contradiction:

Improvenetwork securityVSAvoidfirewall configuration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Firewall rules are pre-configured and stored in association with application volumes before deployment. This preliminary action allows the system to have customized network security rules ready in advance, eliminating the need for time-consuming manual configuration when applications are attached. The pre-prepared rules ensure security reliability while dramatically reducing configuration time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The networking manager automatically detects application volume attachment events and applies the corresponding pre-configured firewall rules without manual intervention. This automation maintains customized network security for each application while eliminating the time consumption and operational overhead of manual firewall configuration, directly resolving the identified technical contradiction.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If dynamic application attachment is implemented to meet current user requirements, then system flexibility is improved, but network traffic management difficulty increases

Engineering Contradiction:

Improvesystem flexibilityVSAvoidnetwork traffic management

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Firewall rules are pre-configured and associated with application volumes before they are dynamically attached to virtual machines. This preliminary preparation ensures that when applications are dynamically attached to meet changing user requirements, the corresponding network traffic management rules are already in place and automatically applied, maintaining ease of operation while preserving system flexibility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The networking manager automatically responds to application volume attachment events by applying the corresponding pre-configured firewall rules. This self-service mechanism allows the system to remain flexible and adaptive to changing requirements while automatically managing network traffic, eliminating the need for manual intervention and maintaining ease of operation despite dynamic changes.

Inventive Principle:

Principle #25Self-service
