Appended Management Information in Distributed Message Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed computing systems, the exchange of management information between machines consumes significant bandwidth due to the need for dedicated management messages, which can lead to inefficiencies in monitoring and data collection.
Innovation Solution
Management information is appended to existing messages flowing through the system, allowing each intermediate machine to add its statistics, reducing the need for additional messages and proportional to the number of machines the message passes through, thereby minimizing network traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If dedicated management messages are exchanged between machines, then management information can be collected comprehensively, but network bandwidth consumption increases significantly
Solution Approach 1:
The patent combines management information exchange with existing application messages. Instead of sending separate dedicated management messages, the system appends management information to messages that are already being transmitted for application purposes. This merging approach allows comprehensive management data collection while utilizing the bandwidth already allocated for application traffic, thereby reducing overall network bandwidth consumption.
Solution Approach 2:
The patent makes existing application messages serve dual purposes: delivering application data and carrying management information. By enabling messages to function both as application communications and as management data carriers, the system eliminates the need for separate dedicated management message channels, thus reducing total network traffic while maintaining comprehensive monitoring capabilities.
2Loss of information
If management information is appended to every message passing through intermediate machines, then comprehensive monitoring data is collected, but message size increases proportionally to the number of machines
Solution Approach 1:
The patent extracts management information from the main application message content and places it in a separate management information field or header. This extraction allows the core application message to remain compact while management data is collected independently. Intermediate machines can add their specific management information without significantly increasing the overall message size, as the management data is structured and efficiently packaged.
Solution Approach 2:
The patent segments management information into discrete, machine-specific components that are appended to messages. Each intermediate machine adds only its own management data segment rather than duplicating all management information from all machines. This segmentation prevents message size from growing proportionally to the total number of machines, as each machine contributes only a small, fixed-size segment.
Data Source
AI summary
A message addressed to an application operating on a destination machine is received at an intermediate machine. Management information is attached to the message, the management information including operating statistics of the intermediate machine. The message is forwarded to the destination machine.
