This study introduces a novel circle quorum system to ensure non-stop Internet services for businesses. This high-availability solution addresses critical network failures, improving quality of service and reducing business risk.

Area of Science:

  • Computer Science
  • Network Engineering
  • Distributed Systems

Background:

  • Business services increasingly rely on distributed computing and "subscriber/push" architectures.
  • Frequent network failures cause significant downtime, impacting business risk and Quality of Service (QoS).
  • Existing cluster technologies effectively ensure high availability on Local Area Networks but struggle with non-stop Internet service over routers.

Purpose of the Study:

  • To develop a non-stop Internet service system addressing the limitations of current high-availability solutions.
  • To apply quorum systems, known for high availability and fault tolerance, to distributed business service networks.
  • To model and implement a novel "circle quorum system" for enhanced Internet service availability.

Main Methods:

Related Experiment Videos

  • Modeling and development of a new quorum system, termed the "circle quorum system."
  • Integration of five distinct protocols to support the quorum system's functionality.
  • Deployment of the system for a real-world business application at Boston Mutual Fund Broker, US.

Main Results:

  • Successful implementation of a non-stop Internet service system.
  • Demonstrated high availability and fault tolerance for Internet-based data services.
  • Provided continuous data services to clients over the Internet, mitigating downtime issues.

Conclusions:

  • The developed circle quorum system effectively ensures non-stop Internet service, a critical need for modern business.
  • Quorum systems are a viable and performant solution for achieving high availability in distributed Internet services.
  • The implemented system significantly improves QoS and reduces business risk by preventing prolonged network downtime.
