Quality of service
The IBM® i quality of service (QoS) solution enables the policies to request network priority and bandwidth for TCP/IP applications throughout the network.
All traffic in your network receives equal priority. Noncritical browser traffic is considered as important as critical business applications. If your chief executive officer (CEO) is giving a presentation using an audio/video application, IP packet priority becomes a concern. It is critical that, during the presentation, this application receives greater performance than other applications.
Packet priority is important to you if you send applications that need predictable and reliable results, such as multimedia. QoS policies can manage packet priority and can also limit data leaving your system, manage connection requests, and control system load. The QoS server must be running to activate the intrusion detection policy.
