Quality of Service provisioning
...................................................................................................................................................................................................................................
QoS provisioning concept
A 3-stage provisioning concept is used for QoS provisioning. This concept can easily
be adapted to different provisioning needs in different network applications.
The basic QoS provisioning concept consists of the following stages:
1. For each port one or more customized flow identification tables (FIT) can be
assigned.
A flow identification table can be assigned either to an entire physical port, or to a
fraction of a physical port, i.e. to a so-called “virtual port”. Only E-NNI trunk
ports can be split into virtual ports each having a flow identification table assigned.
A virtual port can be defined by means of a virtual port descriptor (VPD).
