IP Quality of Service (IPQoS) is a new feature in the Solaris Operating System. IPQoS enables system administrators to provide different levels of network service to customers and to critical applications. By using IPQoS, the administrator can set up service-level agreements. These agreements provide an Internet service provider's (ISP) clients with varying levels of service that are based on a price structure. A company could also use IPQoS to prioritize among applications so that critical applications get a higher quality of service than less critical applications.
For further information, see the System Administration Guide: IP Services.
