rcvwnd: TCP window size of the local host.
delrcvwnd: Delayed receive window—data the local host has read from the
c
onnection, but has not yet subtracted from the receive window
the host has advertised to the remote host. The value in this field
gradually increases until it is larger than a full-sized packet, at
which point it is applied to the rcvwnd field.
SRTT: A calculated smoothed round-trip timeout.
RTTO: Round-trip timeout.
RTV: Variance of the round-trip time.
KRTT: New round-trip timeout (using the Karn algorithm). This field
se
parately tracks the round-trip time of packets that have been
re-sent.
minRTT: Smallest recorded round-trip timeout (hard-wire value used for
c
alculation).
maxRTT: Largest recorded round-trip timeout.
ACK hold: Length of time the local host will delay an acknowledgment to
ca
rry (piggyback) additional data.
IP Precedence value: IP precedence of the BGP packets.
Datagrams Number of update packets received from a neighbor.
Rcvd: Number of received packets.
with data Number of update packets sent with data.
total data bytes Total amount of data received, in bytes.
Sent Number of update packets sent.
Second Congestion Number of update packets with data sent.
Datagrams: Rcvd Number of update packets received from a neighbor.
out of order: Number of packets received out of sequence.
with data Number of update packets received with data.
Last reset Elapsed time since this peering session was last reset.
unread input bytes Number of bytes of packets still to be processed.
retransmit Number of packets retransmitted.
fastretransmit Number of duplicate acknowledgments retransmitted for an out
of ord
er segment before the retransmission timer expires.
partialack Number of retransmissions for partial acknowledgements
(t
ransmissions before or without subsequent
acknowledgements).
Second Congestion Number of second retransmissions sent due to congestion.
