SCTP <strong>Tunable</strong> <strong>Parameters</strong><br />
sctp_max_init_retr<br />
Description<br />
Default 8<br />
Range 0 to 128<br />
Dynamic?<br />
When to Change<br />
Commitment Level<br />
Controls the maximum number of attempts an SCTP endpoint<br />
should make at resending an INIT chunk. The SCTP endpoint<br />
can use the SCTP initiation structure to override this value.<br />
Yes<br />
The number of INIT retransmissions depend on<br />
“sctp_pa_max_retr” on page 161. Ideally,<br />
sctp_max_init_retr should be less than or equal to<br />
sctp_pa_max_retr.<br />

sctp_pa_max_retr<br />
Description<br />
Default 10<br />
Range 1 to 128<br />
Dynamic?<br />
When to Change<br />
Commitment Level<br />
Controls the maximum number of retransmissions (over all<br />
paths) for an SCTP association. The SCTP association is<br />
aborted when this number is exceeded.<br />
Yes<br />
The maximum number of retransmissions over all paths<br />
depend on the number of paths and the maximum number of<br />
retransmission over each path. Ideally, sctp_pa_max_retr<br />
should be set to the sum of “sctp_pp_max_retr” on page<br />
162 over all available paths. For example, if there are 3 paths to<br />
the destination and the maximum number of retransmissions<br />
over each of the 3 paths is 5, then sctp_pa_max_retr should<br />
be set to less than or equal to 15. (See the Note in Section 8.2,<br />
RFC 2960.)<br />
