Command Reference Guide PPP Interface Command Set
The first packet in a flow that is forwarded through the unit will build a flow entry. When a flow entry is
looked up but no entry is found, a RapidRouteBuilder object is allocated and attached to the packet. As the
packet passes through the various processing layers, each subsystem will add processing to the
RapidRouteBuilder. When packet is about to be forwarded out of the egress interface, the
RapidRouteBuilder will be finalized. That is, the flow entry being built will be checked for completeness and
committed to the flow table on the ingress interface. Subsequent flow matches can then bypass the normal
processing layers.
