Abstract:

One of the applications that has driven IT organizations to focus on performance is Voice over IP (VoIP). Voice is, by its very nature, a mission-critical application. Based on their experience over the last century of experience with circuit-switched public telephony, users have come to expect nearly 100% voice availability, fast call set-up and excellent quality. However, when run over a packet network, voice does not always perform as well as it does when run on a circuit-switched network. The resulting user frustration with VoIP issues can have a major impact on how the rest of the company views the IT organization. As will be described in this brief, because of the sensitivity of voice to a range of network parameters, adding bandwidth is even less likely to guarantee acceptable VoIP quality than it is to guarantee the successful performance of other key applications. As a result, IT organizations need an application performance management solution that will specifically monitor voice performance.
