Dynamic Heartbeat Frequency Regulation in Cluster Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heartbeat frequency regulation systems in Cluster Systems are not capable of real-time adjustment according to changing operational conditions, leading to delayed response times for backup hosts when taking over malfunctioning hosts, resulting in incomplete service request responses.
Innovation Solution
A method and system that dynamically adjusts the heartbeat frequency of a host based on user-requested service signal frequencies by establishing a frequency correspondence table, recording and calculating service request signal frequencies, and synchronizing heartbeat frequencies between the host and backup host to match the current service request demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the heartbeat frequency is set manually and kept fixed, then the system operation is simple and stable, but the response time of the backup host is delayed when the service request frequency increases
Solution Approach 1:
The heartbeat frequency is changed from a fixed manual setting to a dynamic parameter that automatically adjusts according to the service request frequency. The host monitors incoming service requests and modifies the heartbeat interval accordingly, allowing the backup host to detect host failures faster when service demand is high, thus resolving the contradiction between simple operation and fast response.
Solution Approach 2:
A feedback mechanism is implemented where the host monitors the frequency of service requests and uses this information to adjust the heartbeat frequency. The system continuously measures service request rates and modifies heartbeat intervals in response, creating a closed-loop control that optimizes failover response time based on actual system conditions.
2Speed
If the heartbeat frequency is increased to reduce response time, then the backup host can take over faster, but the system consumes more energy and generates more network traffic
Solution Approach 1:
The heartbeat frequency dynamically adapts to service request patterns rather than maintaining a constant high frequency. When service demand is low, the heartbeat interval increases, reducing energy consumption and network traffic. When service demand rises, the heartbeat frequency automatically increases to ensure fast failover detection, thus balancing energy efficiency with response speed.
Solution Approach 2:
The system changes the heartbeat frequency parameter based on measured service request frequencies. By adjusting this critical parameter in response to system conditions, the system optimizes the trade-off between energy consumption and failover response time, consuming more energy only when necessary for fast response.
3Adaptability or versatility
If the heartbeat frequency is adjusted manually, then the regulation process is simple, but the system cannot adapt to changing service demands in real-time
Solution Approach 1:
The system performs self-adjustment of the heartbeat frequency without requiring manual intervention. The host automatically monitors service request patterns and modifies its own heartbeat intervals based on observed conditions, enabling the system to adapt to changing service demands autonomously while maintaining operational simplicity.
Solution Approach 2:
An automatic feedback loop is established where the system monitors service request frequencies and uses this information to self-regulate the heartbeat frequency. This automated adaptation mechanism eliminates the need for manual configuration while ensuring the heartbeat frequency always matches current service demands.

AI summary
A system and method for regulating real-time the heartbeat frequency of the host according to the user-requested frequency, wherein the heartbeat frequency of the host is regulated through the service request signal sent from the user's end to the host by making use of a cluster system comprising a host and a backup host. Firstly, a frequency correspondence table is established. The host and the backup host transmit signals to each other at a predetermined frequency, which is set to the most recent heartbeat frequency of the host. Then the transmitting times of a plurality of service request signals are recorded to calculate the frequency of the most recent service request signal. Finally, the most recent heartbeat frequency of the host and the frequency of the most recent service request signal are compared to determine if the heartbeat frequency of the host needs to be regulated.
