The current shipping release of Flextronics Software Systems SUA is Rel 5.0
and is uniquely positioned to meet the Functional and
Performance needs of Next Generation Networks.
Feature list includes
- Compliance to SUA IETF Draft version16
- Message routing based on Global Title Translation as per SCCP specifications is supported.
- Support for the following ITU-T, ANSI, CHINESE and JAPANESE SCCP standards (new ones can be added easily)
- Full Scale and Transparent Support of SCCP Protocol Services (Connectionless and Connection Oriented, all classes 0, 1, 2, 3)
- Supports all GTT functionality as per SS7 standards (e.g. ITU-T, ANSI)
- Pre-integrated with Flextronics Software Systems SCTP implementation (based
on Internet RFC 2960). Supports SCTP Socket APIs as
per IETF draft tsvwg-sctpsocket version 07
- Support for MTSafe, Traces, Statistics and Redundancy.
- Support for Ipv6 IP addresses
- SUA supports both Single & Double exchange modes in the IPSP-IPSP communication scenario
- Relay functionality support equivalent to that of SCCP
- Supports maintaining status of SS7 point codes from various Signaling Gateways
- Comprehensive statistics supported. Common statistics counters, as per IETF M3UA MIB supported (since no IETF SUA MIB available) & Q.752
- Congestion Control as per International/National MTP3 variants
Interoperability
To test the interoperability of its software stack
with other vendors, Flextronics Software Systems (formerly HSS) has actively
participated in all SUA interoperability events.
The last SUA interoperability Test Event (Plugtest)
was held at ETSI facilities at Sophia Antipolis, France
from 1 September - 5 September 2003. About 20 companies
participated in this event for testing their version
of SUA stack against other companies. Flextronics Software Systems SUA stack
in all SG/ASP and IPSP scenarios was successfully tested.
Redundancy
SUA Stack redundancy feature supports both HOT STANDBY
and COLD STANDBY redundancy Models. These models of
redundancy are called Transparent Update and Stable
State Update Model in Flextronics Software Systems terminology of redundancy
implementation. SUA redundancy features also support
mechanism to bring a new or recovered Node to be synchronized
with current Active Node.
Flexible Node
This unique feature allows a single SIGTRAN Node (single
instance of software stack) to act as a ASP, SGP and
IPSP Node at the same time and also connect to all types
(ASP, SGP and IPSP nodes) of Nodes at the same time.
This flexibility allows the Flextronics Software Systems SUA to be easily placed
in very complex Network configurations.
Distributed Application Server
To cater to scalability requirements of next generation
Products, Flextronics Software Systems SUA stack supports mechanisms to enable
distributed software architecture. In this distributed
architecture SUA Layer can run on multiple nodes. This
along with Redundancy Feature allows products to have
n + k redundancy scheme, where there are "n"
active Nodes and "k" standby Nodes. Also all
intricacies of internal architecture are hidden from
external world as all of these Nodes share the same
view of the network.
Ports Available
All Flextronics Software Systems (formerly HSS) stacks including SUA stack is
based on HSS AAPE™ Architecture, according
to which all platform (both operating system and hardware)
specific interactions are wrapped to a single module.
With this, effort to port core stack code to a different
platform is significantly reduced. On an average it
takes less than a couple of weeks to port and test stack
code on a new platform. SUA stack code is available
for following Operating Systems.
- Linux ( Tested with Red HATversion 7.2 )
- SunOs (Version 2.5 and over)
- VxWorks (Version 5.4.2)
Performance
A lot of consideration is given to optimization of software
stack for memory and processing power requirements,
during the design phase. This is done keeping in mind
field deployment of the stacks. The SUA stack has been
optimized for peak performance with practically no effect
on scaling the network. For performance statistics please
