The capabilities of your internal equipment and other equipment outside your network have enormous effects on quality of service (QoS) results.
Integrated service policies require applications that are enabled by ReSerVation Protocol (RSVP). Because the i5/OS® applications are not initially RSVP-enabled, enable them to use RSVP. To enable your applications, you need to write special programs using the RSVP APIs or qtoq QoS socket APIs. These programs allow your applications to use RSVP.
The routers, switches, and even your own operating systems must have the capability to use QoS. To use differentiated services policies, your equipment must be enabled for Differentiated Services. This means that the network node must be able to classify, meter, mark, shape, and drop IP packets (traffic conditioners).
To use integrated services policies, your equipment must be RSVP-enabled. This means that the network nodes must also be able to support RSVP.
