Notes from discussions about ``A Passive Network Appliance for Real-Time Network Monitoring'' Page 241 (3), 2nd column: "our software must first decode the [...] headers to extract the flow 5-tuple". Later examples show a 6-tuple, adding the network-protocol, the software _extracts_ a 6-tuple, but _hashes_ on the 5-tuple described. Page 242 (4), Footnote 1: This number was derived using a packet trace from a previous version of the PNA kernel module in which there were only 131,072 entries. In the updated (> 8 million entries) version, the probe limit could be reduced even further without significant loss.
