Computer - Engineering

Fault-tolerance technology has become an important branch in computer systems, and is widely used in many other fields. Fault-tolerance schemes can be used to increase the Availability and Reliability of network service systems. This thesis implemented a Fault-Tolerance Web server system that supports software and hardware failure bypassing, depending on the Dual-Server Hot-Standby principle, where an efficient transparent fail-over scheme is used to provide fault-tolerant network service.
