Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing command line environments for system administration are inadequate for remote operations, particularly in complex network systems, as they do not efficiently support concurrent execution of commands across multiple remote nodes and lack features for persistent sessions and result aggregation.

Innovation Solution

A command line environment that establishes persistent sessions with multiple remote nodes, allowing concurrent execution of commands and aggregating results, while distributing the task of establishing sessions to improve performance and simplify large-scale administrative tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional command line environments are used for remote system administration, then basic administrative tasks can be performed, but concurrent execution of commands across multiple remote nodes is inefficient and lacks persistent session support

Engineering Contradiction:

Improveremote system administration efficiencyVSAvoidconcurrent command execution capability

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system segments the remote administration task by establishing separate persistent sessions with each remote node, allowing independent concurrent execution of commands across multiple nodes while maintaining individual session states

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Persistent sessions are established in advance before commands are executed, creating pre-configured communication channels that enable efficient concurrent command execution without repeated connection overhead

Inventive Principle:

Principle #10Preliminary action

2Productivity

If multiple remote sessions are established for concurrent command execution, then productivity improves, but system complexity and session management overhead increase

Engineering Contradiction:

Improveconcurrent command executionVSAvoidsession management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

Each persistent session autonomously manages its own state and execution context independently, allowing multiple sessions to operate concurrently without requiring complex centralized coordination or synchronization mechanisms

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If command results from multiple remote nodes are collected, then comprehensive administration capability is achieved, but result aggregation and processing becomes complex

Engineering Contradiction:

Improveremote node coverageVSAvoidresult aggregation complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Results from each remote node are collected and processed independently through separate session channels, then aggregated at a higher level, dividing the complex aggregation task into manageable independent units

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The persistent session mechanism provides a universal interface for both command execution and result collection across different remote nodes, handling diverse administration tasks through a unified approach

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A command line environment is configured to receive a command line that implicates a plurality of remote nodes. The command line environment is configured to establish a session, which may be persistent, to each implicated remote node, and to initiate execution of the remote command on those nodes. The session may be assigned to a variable, and the remote execution may be performed concurrently. Results of the remote execution are received and may be aggregated into an array. The command line environment may distribute the task of establishing sessions to other systems to improve performance.
