It uses 3 CPU cores connected in a chain through SW rings (NICs --> Core A --> Core B --> Core C --> NICs) 1. Core A: reads packets from NIC ports and writes them to SW queues; 2. Core B: instantiates a Packet Framework pipeline that uses ring reader input ports, a table whose type is selected trhough command line arguments (--none, --stub, --lpm, --acl, --hash[-spec]-KEYSZ-TYPE, whith KEYSZ as 8, 16 or 32 bytes and TYPE as ext (Extendible bucket) or lru (LRU)) and ring writers output ports; 3. Core C: reads packets from SW rings and writes them to NIC ports. Please check the Intel DPDK Sample App Guide for full description.
