8.3 TRAFFIC SHAPING
You can set traffic parameters for a virtual channel by specifying a service category. A service category defines
bandwidth characteristics and delay guarantees. You can then apply a different service category to each virtual channel.
This gives you more control of your network resources, and more options to accommodate different user needs.
You can define the following service categories:
Unspecified Bit Rate (UBR) This service category is strictly best effort and runs at the available bandwidth.
Users may limit the bandwidth by specifying a PCR value. The SCR and MBS are
ignored. This service class is intended for applications that do not require specific
traffic guarantees. UBR is the default.
