PRODUCT SHEET Signaling Solutions
Tieto DSC -
Diameter Signaling Controller
Tieto Signaling Solutions has an established portfolio of signaling products and
services that are used throughout the world. Our broad range of high-quality
signaling products are matched with our extensive service offerings to secure
your network connectivity.
Product overview
The Diameter Signaling Controller product provides a complete system solution to intelligent routing of Diameter
traffic in 4G/LTE networks. It is predicted that mobile data traffic will grow in the region of 4000% until year 2020
and this will put severe pressure on the telecom network operators core network to handle the corresponding
growth in Diameter signaling traffic.
Key benefits
The Tieto Diameter Signaling Controller provides the
following benefits to the 4G/LTE network operator:
» Reduced overall signaling load (Removal of full
mesh signaling)
» Simplified network configuration scenarios at roll
out and upgrade
» Multi-vendor network node interworking
» Secure and efficient intra network connectivity
(e.g. topology hiding)
» Allows easy scalability of network resources
» Intelligent and adaptable routing functionality
» Can optionally support interworking with legacy
protocols such as SS7, RADIUS, LDAP and
SOAP via co-location with the Tieto Diameter
Mediation Gateway (DMG)
» Runs on standard COTS Linux servers and ATCA
Linux systems
» Can be used both as an embedded Diameter
routing/loadsharing engine and as a stand-alone
DSC node
Features
» The Tieto Diameter Signaling Controller consolidates
several Diameter applications into one
solution:
• Diameter Routing Agent (DRA)
3GPP TS 29.213
• Diameter Edge Agent (DEA) GSMA IR-88
• Diameter Load Balancer
• Diameter Proxy Agent RFC 3588
• Diameter Relay Agent RFC 3588
• Diameter Redirect Agent RFC 3588
» Flexible source and destination based routing
• Route on Realms, Host ID, Application ID
and AVP Content or combinations thereof
• Destination groups with load sharing (roundrobin)
or priority based within/among groups
• Forking of messages to multiple destinations
• Stateless and stateful (session aware)
routing
» Configurable modification of message AVP
content
• Content can be added, modified or removed
» High Availability and Scalability using Tieto
Horizontal Distribution Architecture:
• Built for multi-core server platforms
• Horizontal distribution over multiple servers
» Configurable Dictionary for proprietary Vendors,
Commands and AVPs implementations
» Can also act as a Diameter end node (server or
client) serving co-located application
• C/C++ and Java J2SE API’s for application
integration
» Transport protocols:
• SCTP (IETF RFC 2960)
• TCP
• IPv4 & IPv6
» Transport security:
• Diameter over TLS
» Capacity:
• More than 120.000 Diameter routing transactions/second
using quad-core Intel Xeon
2,4GHz processor
» Congestion and overload protection
» Operation & Maintenance:
• Built-in web server for remote GUI management
• Local/Remote Command Line Interface
• SNMP Alarm Management
» Portable software architecture
• Easy to embed in customer application

» 3GPP TS 29.211 & TS 29.212, Rx interface
» 3GPP TS 29.209, Gq interface
» 3GPP TS 29.299, Gy interface
The DSC is compliant with 3GPP releases 7, 8, 9, 10
and 11.
The DSC is IMS ready, supports all 3GPP specific
identities, command codes and result codes defined
in TS 29.230.
Alarm interface
Alarms are normally sent as SNMP traps to an external
SNMP manager via Ethernet connection. Alarm
notifications can also be viewed locally. Alarms are
saved in an alarm log.
User Security
The Linux system is hardened to prevent remote
access and system manipulation
HW Configurations
The Diameter Signaling Controller is built for standard
Linux x86 server platforms
