These technologies include Voice-over-IP (VoIP), the packet-switched alternative to old-fashioned circuit-switched telephony. To enable VoIP traffic, application servers must provide carrier-grade reliability that guarantees high service availability (99.999% uptime or better). These systems must also scale to handle hundreds of thousands of calls and provide predictable performance and high speech quality. The telecommunications industry is undergoing enormous changes as equipment providers migrate from proprietary platform architectures to open software environments and commercial off-the-shelf (COTS) platform architectures.

They require 24 hours a day and 365 days a year service availability and their downtime should not exceed five minutes per year and that includes hardware and software upgrades. These systems require carrier-grade reliability that guarantees high service availability, 99.999% up... (more)
