DSCP-to-IEEE 802.1p Priority Mapping
DiffServ is a class of service (CoS) model that marks packets with DiffServ Code Points (DSCPs) so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route. DSCP-to-IEEE 802.1p mappings allow a device to prioritize all incoming traffic based on the DSCP value according to the mapping table.
