I don't believe reordering is tracked on the receiver side but on the sender, there are SNMB_MIB items. They can be tracked and can be viewed using nstat/netstat # nstat -az | grep -i reorder TcpExtTCPFACKReorder 0 0.0 TcpExtTCPSACKReorder 0 0.0 TcpExtTCPRenoReorder 0 0.0 TcpExtTCPTSReorder 0 0.0
Thanks. For me after a 64MiB download, I have an increase of one FACK, one SACK and one TS reorder. So my connection probably does even less reordering than I thought, and thus isn't particularly relevant to this conversation. I'll shut up now and go back to playing with ATM. -- dwmw2
