Darren Kerr of Cisco pointed out the fact that flows are not bi-directional, i.e. a TCP session is two flows, and that meaningful FTP data is FTPD, which stand for FTP Data, so it throws off some of the hypotheses discussed here. Some more itsy bitsy data until I have real stuff to play with: This is from a customer aggregation box. dgd#sh ip ca flow IP packet size distribution (3992M total packets): 1-32 64 96 128 160 192 224 256 288 320 352 384 416 448 480 .005 .489 .058 .016 .013 .008 .009 .012 .011 .015 .004 .005 .002 .002 .002 512 544 576 1024 1536 2048 2560 3072 3584 4096 4608 .005 .003 .142 .000 .114 .075 .000 .000 .000 .000 .000 IP Flow Switching Cache, 10539 active, 54997 inactive, 257164236 added 0 flows exported, 0 not exported, 0 export msgs sent 3 cur max hash, 257 worst max hash, 11801 valid buckets 0 flow alloc failures statistics cleared 1423044 seconds ago Protocol Total Flows Packets Bytes Packets Active(Sec) Idle(Sec) -------- Flows /Sec /Flow /Pkt /Sec /Flow /Flow TCP-Telnet 1566034 1.1 129 70 142.2 115.3 44.4 TCP-FTP 5836648 4.1 6 91 26.3 12.4 45.7 TCP-FTPD 3560889 2.5 86 464 216.5 49.2 45.7 TCP-WWW 139280025 97.8 11 319 1137.3 8.2 45.9 TCP-SMTP 22840124 16.0 10 160 166.6 9.8 45.9 TCP-X 58694 0.0 127 176 5.2 106.0 44.3 TCP-BGP 1339769 0.9 2 50 2.6 9.2 44.5 TCP-Frag 123389 0.0 9 306 0.7 17.6 45.3 TCP-other 20351999 14.3 70 354 1008.7 61.2 45.2 UDP-DNS 39827050 27.9 3 103 96.7 6.7 45.8 UDP-NTP 5321916 3.7 2 76 7.6 0.8 45.9 UDP-TFTP 106 0.0 4 94 0.0 22.2 44.2 UDP-Frag 1829 0.0 59 296 0.0 69.3 45.1 UDP-other 7809191 5.4 19 142 108.4 27.6 45.3 ICMP 9140968 6.4 3 154 24.5 7.7 45.8 IGMP 39621 0.0 37 422 1.0 44.5 44.9 IPINIP 44911 0.0 626 282 19.7 104.2 43.7 GRE 12545 0.0 2233 272 19.6 208.4 42.6 IP-other 587 0.0 34 525 0.0 18.2 46.2 Total: 257156295 180.7 16 302 2984.5 14.1 45.8 -dorian
