ABSTRACT:
A multiport switch includes an action generator that creates action tags describing how data frames received by the switch are to be forwarded. A port filter generates policy equations and a differential services code point (DSCP) signal for the received packets. A decoder and an action memory in the action generator choose the highest priority policy equation and use the policy equation to look up priority information for the data frame. A state machine in the action generator receives the DSCP signal. A result tag interface receives a DSCP field from the state machine and the priority information from the action memory. Based on these signals, the result tag interface constructs the final action tag.
