Changes
2.1
DTS – Per-LSS User module_id’s
When using DTS between SCCP and the Local Sub-System (ie. DTS Mode A),
this release enhances operation of the SCCP_LSS command to allow Local
Sub-Systems using DTS to make use of different USER_ID (module_id)
values (rather than having to use the fixed DTC module_id).
This facilitates additional flexibility in designing systems with multiple hosts
and multiple Local Sub-Systems (including the ability for traffic to bypass DTC
as it passes up the stack). By default incoming SCCP traffic is shared across
all available hosts, however use of the DTS_ROUTE command allows the user
to create specific host assignments.
2.2
SCTP – Enhanced internal architecture
This release includes an updated SCTP implementation which has been
enhanced to spread the processing load over multiple CPU cores to provide
improved utilization of available CPU bandwidth.
The updates to SCTP also address a number of protocol issues and errors
including correcting an issue that could result in SCTP locking up and causing
a restart of the unit.
2.3
M3UA – Failure to Restore Link
This release corrects an issue within M3UA that potentially could result in a
failure to correctly restore an Association following failure of an active link.
2.4
Diagnostics
This release introduces some additional diagnostic capabilities and measures
to guard against excessively large system logs in the snapshot file.
