RFC3873 defined SCTP_MIB_CURRESTAB:
sctpCurrEstab OBJECT-TYPE
SYNTAX Gauge32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of associations for which the current state is
either ESTABLISHED, SHUTDOWN-RECEIVED or SHUTDOWN-PENDING."
REFERENCE
"Section 4 in RFC2960 covers the SCTP Association state
diagram."
If the T4 RTO timer expires many times(timeout), the association will enter
CLOSED state, so we should dec the number of SCTP_MIB_CURRESTAB, not inc the
number of SCTP_MIB_CURRESTAB.
