Asymmetric Communication Paths for Distributed Database Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current big data processing systems face challenges in managing installation, setting, and control for distributed databases on a single PC server, particularly in transmitting state information and prioritizing instructions based on processing importance.
Innovation Solution
A management system and method that employs a system management master node and agent node with asymmetric communication paths to transmit state information and prioritize instructions, allowing for the integration of installation, setting, and control of distributed databases, including the use of rank codes to determine instruction importance and queue positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single PC server is used to manage distributed databases, then device complexity is reduced, but management capability for installation and control becomes insufficient
Solution Approach 1:
The management system is segmented into a master node and multiple agent nodes, where the master node handles high-level management decisions and agent nodes execute specific installation and control tasks on individual database servers. This segmentation allows a single PC server to effectively manage distributed databases by distributing management functions across multiple specialized components.
2Ease of operation
If state information is transmitted without prioritization, then communication simplicity is maintained, but instruction processing efficiency deteriorates
Solution Approach 1:
The system performs preliminary action by assigning priority levels to instructions before they are transmitted through the communication channel. The master node tags instructions with priority information, and agent nodes use these pre-assigned priorities to queue and process instructions appropriately, ensuring critical instructions are handled first without requiring complex real-time communication protocols.
3Adaptability or versatility
If installation and control are managed separately, then functional specialization is achieved, but system integration complexity increases
Solution Approach 1:
The agent nodes are designed with multi-functionality, capable of performing both installation tasks and control operations on database servers. This universal design allows the system to maintain functional specialization between master and agent nodes while avoiding the complexity of separate specialized systems for installation and control, as each agent node can handle multiple types of operations.

AI summary
Provided is a management system for a big data processing device that includes a system management master node and at least one system management agent node communicatively coupled to the system management master node over a network. A first request-based communication path may be provided for transmitting data from a system management agent node to the system management master node and a second response-based communication path is provided for transmitting data from the system management master node to the system management agent node. The system management agent node may be configured to detect whether an instruction is included in a response received over the second communication path.
