DSI Development Package for Linux - Release Notes Release Notes for V6.04

3 Other Changes

3.1 SCTP Congestion Control

The congestion control mechanism in previous releases of the SCTP binary

(but not the SCTPN binary) limited maximum throughput to 1,800

messages/s per association. This restriction no longer exists.

3.2 SCTPN - Association Reconfiguration (IPY00081007)

It is possible to dynamically reconfigure SCTP association to add and remove

addresses. The association being modified should first be deactivated and

then reconfigured before being activated again. A potential problem causing

excess CPU utilization and association failure as a result of dynamic

reconfiguration has been corrected.

3.3 s7_log – PCAP Corruption (IPY00081077)

Previous releases of s7_log created corrupt PCAP log files when capturing

trace event messages (SS7_MSG_RX_IND, API_MSG_TX_REQ and

API_MSG_RX_IND) from a module. This resulted in WireShark displaying

corrupt packages and has now been corrected.

3.4 s7_mgt – Global Title Address Limitations

Previous releases of s7_mgt limited global title addresses to 8 octets or less.

This has been corrected.

3.5 s7_mgt – SCCP and TCAP Trace Module Id

This release supports setting the trace_id for SCCP and TCAP to the value

specified in the TRACE_MOD_ID command (subject to using a version of

SCCP and TCAP that supports the configurable trace_id). In previous releases

this command was not supported for SCCP or TCAP protocols so the default

value of 0xef was used.
