Networking and business groups worldwide are rapidly adopting the convergence of voice, data and video over a single network for the simple reason that it saves money, administrative time and energy, and keeps infrastructure flexible and simple to manage. In particular, technologies like VoIP, video, and Web services are targeted to deliver greater productivity, improved customer response, streamlined business processes, and much greater efficiencies.

However, as many companies seeking to deploy this new panacea are discovering, the path to convergence has many challenges. The issue facing the enterprise is the growing gap between application performance requirements and what the network is able to deliver.

Yet it is the end users - including employees, customers, partners, who drive the expected level of performance. This might be dictated by productivity metrics, business customer needs, or competitive threats. The objective is simple. Each application must perform consistently against a well-understood set of quality metrics. This is true no matter how many data, VoIP, and video applications are sharing the network.

Achieving this requires a solution enabling the IP network to become "application aware." Unfortunately, the underlying IP network - which has always been optimized for "better, faster and cheaper," forwarding of packets - does not provide the accuracy and control needed to assure application performance at the end user level.

Applying Intelligent Application Performance Control to Manage the Application Performance Gap
