Reliable time delay-constrained cluster computing

摘要

Apparatus and method of cluster computing are described. The present invention provides a useful compromise between the manageability, power, and ease of use of centralized systems and the reliability, fault-tolerance, upgradability, and scalability of distributed systems. Moreover, the present invention provides fault-tolerance and security while adhering to real-time to respond constraints or bounds. The invention is described in preferred embodiment examples in the context of two clustered applications: a telecommunication switch-controller and a Web servers, although many practical applications will benefit from the present invention.
