Application Maps consist of a list of applications and known IP/port mappings for those applications (if any). The information they contain is used by the Edge deep packet inspection (DPI) engine to inform how traffic flows are categorized for the purposes of traffic accounting (i.e. in “Flow Stats” records), and for matching traffic to firewall rules, business policies, etc. Each Edge is assigned an Application Map as part of its “Software Image”. Edges that are not specifically assigned a Software Image inherit theApplication Map assigned to the the Customer-default Operator Profile.
