From 3a087e951d96f509c75344ad6791591e10e4f1cd Mon Sep 17 00:00:00 2001 From: Ivan Nardi <12729895+IvanNardi@users.noreply.github.com> Date: Tue, 11 Jan 2022 15:23:39 +0100 Subject: Add a "confidence" field about the reliability of the classification. (#1395) As a general rule, the higher the confidence value, the higher the "reliability/precision" of the classification. In other words, this new field provides an hint about "how" the flow classification has been obtained. For example, the application may want to ignore classification "by-port" (they are not real DPI classifications, after all) or give a second glance at flows classified via LRU caches (because of false positives). Setting only one value for the confidence field is a bit tricky: more work is probably needed in the next future to tweak/fix/improve the logic. --- tests/result/upnp.pcap.out | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'tests/result/upnp.pcap.out') diff --git a/tests/result/upnp.pcap.out b/tests/result/upnp.pcap.out index e2809ce8f..f320f01e4 100644 --- a/tests/result/upnp.pcap.out +++ b/tests/result/upnp.pcap.out @@ -1,8 +1,9 @@ Guessed flow protos: 2 DPI Packets (UDP): 14 (7.00 pkts/flow) +Confidence Match by port : 2 (flows) WSD 14 9912 2 - 1 UDP [fe80::3441:3d24:6d30:a807]:58932 -> [ff02::c]:3702 [proto: 153/WSD][ClearText][cat: Network/14][7 pkts/5026 bytes -> 0 pkts/0 bytes][Goodput ratio: 91/0][5.63 sec][bytes ratio: 1.000 (Upload)][IAT c2s/s2c min/avg/max/stddev: 118/0 938/0 2000/0 752/0][Pkt Len c2s/s2c min/avg/max/stddev: 718/0 718/0 718/0 0/0][PLAIN TEXT (xml version)][Plen Bins: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,100,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] - 2 UDP 192.168.61.66:58931 -> 239.255.255.250:3702 [proto: 153/WSD][ClearText][cat: Network/14][7 pkts/4886 bytes -> 0 pkts/0 bytes][Goodput ratio: 94/0][6.64 sec][bytes ratio: 1.000 (Upload)][IAT c2s/s2c min/avg/max/stddev: 179/0 1107/0 2004/0 740/0][Pkt Len c2s/s2c min/avg/max/stddev: 698/0 698/0 698/0 0/0][PLAIN TEXT (xml version)][Plen Bins: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,100,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] + 1 UDP [fe80::3441:3d24:6d30:a807]:58932 -> [ff02::c]:3702 [proto: 153/WSD][ClearText][Confidence: Match by port][cat: Network/14][7 pkts/5026 bytes -> 0 pkts/0 bytes][Goodput ratio: 91/0][5.63 sec][bytes ratio: 1.000 (Upload)][IAT c2s/s2c min/avg/max/stddev: 118/0 938/0 2000/0 752/0][Pkt Len c2s/s2c min/avg/max/stddev: 718/0 718/0 718/0 0/0][PLAIN TEXT (xml version)][Plen Bins: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,100,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] + 2 UDP 192.168.61.66:58931 -> 239.255.255.250:3702 [proto: 153/WSD][ClearText][Confidence: Match by port][cat: Network/14][7 pkts/4886 bytes -> 0 pkts/0 bytes][Goodput ratio: 94/0][6.64 sec][bytes ratio: 1.000 (Upload)][IAT c2s/s2c min/avg/max/stddev: 179/0 1107/0 2004/0 740/0][Pkt Len c2s/s2c min/avg/max/stddev: 698/0 698/0 698/0 0/0][PLAIN TEXT (xml version)][Plen Bins: 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,100,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] -- cgit v1.2.3
