WAN and LAN-side statistics
WAN and LAN-side statistics include these items:
LAN Bytes
Displays the total LAN bytes transmitted.
WAN Bytes
Displays the total WAN bytes transmitted.
Retransmitted
Displays the total packets retransmitted.
Fast Retransmitted
Displays the total packets fast retransmitted. Fast retransmit reduces the time a sender waits before retransmitting a lost segment. If an acknowledgment is not received for a particular segment with a specified time (a function of the estimated round-trip delay time), the sender assumes the segment was lost in the network, and retransmits the segment.
Timeouts
Displays the number of packet transmissions that timed out because no ACK was received.
Congestion Window
Displays number of unACKed packets permitted, adjusted automatically by the SteelHead, depending on WAN congestion.
