Table 1-1 SCTP Parameters Supported by the ndd Command (continued)
DescriptionParameter
Specifies the default number of times a DATA,
SHUTDOWN, or HEARTBEAT message is retransmitted
to a particular address of an association, before
SCTP considers that address inactive. If an address
is inactive, SCTP sends packets to an alternate active
address, if the peer has more than one address. If
there are no alternate active addresses, then the
primary address is used for n number of retries,
where n is the value specified in sctp_max_assoc_retr.
After that, the association is treated as aborted.
sctp_max_path_retr
Specifies the default value to advertise to the peer
at the receive window size (in bytes). This amount of
data can be either in-flight or waiting to send to a
user before the peer is flow-controlled.
sctp_a_rwnd
Specifies the maximum number of 'out' streams that
can be used by an association. The SCTP user cannot
use a higher value, even if the per-association option
is used.
sctp_max_out_streams
Specifies the default number of 'out' streams that
are requested for an association. The actual number
allocated depends on the number of ‘in’ streams
allowed by the peer. The SCTP user can override
this value using the per-association option.
sctp_default_out_streams
Specifies the maximum number of 'in' streams that
can be used by an association. If a peer specifies a
number that is greater than sctp_max_in_strms, then
the value specified in sctp_max_in_strms is used
instead. However, the SCTP user can override this
value using the per-association option.
sctp_max_in_streams
Specifies the default minimum time (in
milliseconds) for the retransmission timer.
sctp_rto_min
Specifies the default maximum time (in
milliseconds) for the retransmission timer.
sctp_rto_max
Specifies the default initial time (in milliseconds)
for the retransmission timer.
sctp_rto_initial
