network vulnerability scan

The high-level network vulnerability scan of QoS technologies in a converged network is to abstract the fact that there is only one network and to make voice, video, and data convergence appear transparent to the end users. To achieve this goal, QoS technologies allow different types of traffic to contend inequitably for network resources. Real-time applications, such as voice or interactive video, can be given priority or preferential services over generic data applicationsbut not to the point that data applications are starving for bandwidth.

QoS is defined as the measure of a system's service availability and transmission quality. Service availability is a crucial foundation element of QoS. Before any QoS can be implemented successfully, the network infrastructure should be designed to be highly available. The target for high availability is 99.999 percent uptime, with only 5 minutes of downtime permitted per year. The transmission quality of the network vulnerability scan is determined by the following factors
