Definition
Communication service providers face the seemingly impossible challenge of maintaining service continuity while regularly making changes and upgrades to network equipment, computing platforms, and application software. To remain competitive in a world that operates 24 hours a day, seven days a week, service providers must protect against unexpected failures while managing the evolution of service logic, platform software, and system hardware. Thus, solutions such as the HP OpenCall computing platform have been designed to tolerate hardware failures and reduce the risk of service outage as a result of software failures.

Overview
This tutorial discusses the challenge of providing continuous service availability and presents an overview of the technologies that can be used in ensuring mission-critical service continuity for today’s computer-based communications network.
