Test box is treated with mirrored traffic that is routed by production linux router (with non-smp kernel). It's usual traffic generated by broadband clients. Some of the characteristics: bandwidth used: ~40/40 Mbit (up/down) pps: ~15k number of clients: ~550 dump of packet sizes: Packet size | Count 1 to 75: 186501 76 to 150: 14145 151 to 225: 3285 226 to 300: 2088 301 to 375: 3632 376 to 450: 2097 451 to 525: 1513 526 to 600: 3069 601 to 675: 20081 676 to 750: 1294 751 to 825: 1189 826 to 900: 885 901 to 975: 2207 976 to 1050: 1333 1051 to 1125: 1192 1201 to 1275: 3036 1276 to 1350: 3709 1351 to 1425: 3453 1426 to 1500+: 185318 protocol breakdown: most of the traffic is IPv4, some UDP and a little bit of ICMP Don't know if it's important, but box is connected to switch by a 802.1q trunk. Each of vlan interfaces has egress shaping on it + dedicated ifb device attached to ingress qdisc and ingress shaping on ifb device. Is any additional information needed? --=20 Marek Kierdelewicz Kierownik Dzia=B3u System=F3w Sieciowych, KoBa Manager of Network Systems Department, KoBa tel. (85) 7406466; fax.
