Today's highly competitive telecommunications environment allows for very few errors. In most markets, consumers and businesses can choose from multiple service providers and can compare the quality of service (QoS) each offers. Additionally, the rapid technological development of a wide variety of applications over recent years translates into "something for everyone." The widespread business and consumer acceptance of services like VoIP, BlackBerry®, and Mobile TV means that many people carry their homes and offices in their pockets and briefcases utilizing a broad range of applications. Increasingly they require the ability to transmit voice, text data, and even videos on these devices at any time and from any place, and without any service degradation or interruptions. And, as these devices proliferate and service levels generally improve, consumer expectations rise, raising the bar for more complex QoS. Network performance management is no longer a convenience, but has become a necessary tool to keep pace with market demand to attract new customers as well as to retain existing ones.
The Quest to Reduce CAPEX and OPEX
Consider the fast pace of an application "life cycle." Many end users pride themselves on their early adoption of the latest technologies, and service providers are eager to accommodate them. Yet this is often easier said than done. Different applications have different requirements and are

which applications are currently running (perhaps even unauthorized applications), as well as indicating routine and predictable usage trends per consumer or business group. Such accurate, real time network assessment capabilities provide a high level of visibility for applications and network performance, paving the way for a sound CAPEX strategy by allowing for effective capacity planning and the quick and successful ramp-up of new applications. Without this, network operators have no other way of "seeing" network traffic in order to prepare for it and to respond to it appropriately.

becoming increasingly complex and sophisticated. For example, data is elastic and can bounce back from network delays and congestion, whereas mobile voice and video applications are rigid and suffer quality degradation if information packets are delayed or lost.
As new applications are added, effective network performance management solutions can support establishing a baseline for network utilization. This includes identifying

Robust network performance management tools can help reduce OPEX with real time tracking that alerts operators to service degradations like latency, jitter, or packet loss. Any problems that might arise are instantly visible to operators, who literally can see where and when something is going wrong on the network and correct it before it affects the quality of the user experience or the performance of other applications. Network operators can then quickly troubleshoot the underlying network to figure
