IP Service—Functional Overview
Qbins
Qbins store cells and serve them to an interface based on bandwidth availability and CoS priority (see
Figure 10-5. For example, if CBR and ABR cells must exit the switch from the same interface, but the
interface is already transmitting CBR cells from another source, the newly-arrived CBR and ABR cells
are held in the Qbin associated with that interface. As the interface becomes accessible, the Qbin passes
CBR cells to the interface for transmission. After the CBR cells have been transmitted, the ABR cells
are passed to the interface and transmitted to their destination.
