The use of converged IP networks for voice, data and video is an unmistakable trend that is growing stronger every day. Combining voice, video and data traffic on a single network can provide cost savings, operational efficiencies and innovative applications. However, if IP networks are not configured, engineered and managed for real-time, delay-sensitive voice and video traffic, then the result can be high latency, packet loss, jitter and network congestion that makes for garbled voice and freeze-frame video. Today's predominant QoS technologies, including Differentiated Services (DiffServ) and Integrated Services (IntServ/RSVP), require automated configuration, control and management tools to provide the guaranteed service quality that enterprise end-users expect. A good solution is needed to provide the critical enhancements/tools that truly enable "toll quality" voice and "business quality" video conferencing. In this talk we cover how such a solution configures, manages and enhances standard QoS technologies to provide guaranteed voice and video service quality
