pmacct, a new accounting and aggregation tool for IPv4/IPv6 traffic
pmacct is a small set of tools to account and aggregate IPv4 and IPv6 traffic; aggregation revolves around the key concept of communication primitives which may be arbitrarily combined to form complex aggregation methods; data is collected either using libpcap or through Cisco NetFlow v1/v5/v9. Aggregates can be stored into memory tables and SQL databases.
